The Future of India’s EV Industry a Shift Away from NMC Technology

Vikas Aggarwal, Founder & MD – Ipower Batteries Pvt Ltd

As we see the electric vehicle (EV) market growing in India, there’s a noticeable shift in the choice of battery technology. Until now, most EVs have used Nickel Manganese Cobalt (NMC) batteries. But we’re now seeing a strong movement toward Lithium Iron Phosphate (LFP) batteries. This shift is mainly driven by the need for more cost-effective, safer, and reliable battery options. Let me walk you through the current trends and why this transition is gaining momentum.

The Challenges with NMC Batteries

Now, NMC batteries have been the dominant technology for EVs, not just in India, but globally. They have a high energy density, which means they’re great for electric cars that need to go long distances. But they come with some serious challenges.

For one, NMC batteries rely on cobalt and nickel, two metals that are expensive and difficult to source. Most of the world’s cobalt comes from the Democratic Republic of Congo, and the mining conditions there are a big concern—things like child labor and unsafe practices make it ethically problematic. Nickel also has its issues, especially environmental ones. So, both of these metals are in short supply, and their prices can swing a lot, which drives up the cost of NMC batteries.

Secondly, they’re just expensive. Since India is a very price-sensitive market, the high cost of NMC batteries makes it harder for people to afford electric vehicles. The price of cobalt and nickel directly affects how much these batteries cost to make, and that cost gets passed on to the consumer.

Lastly, there’s the environmental and safety angle. Mining cobalt and nickel is tough on the environment, causing things like soil and water contamination. Plus, NMC batteries can sometimes overheat—especially in India’s hot climate—which can lead to thermal runaway, where the battery overheats and possibly catches fire. This isn’t ideal.

The Growing Market for LFP Batteries in India

In recent years, LFP batteries have started to take off in India. Globally, the LFP market is projected to reach over USD 50 billion by 2030, and India is a key player in that growth. In fact, in 2023, LFP batteries already made up more than 40% of India’s EV battery market, mostly in electric two-wheelers and buses.

Looking ahead to 2025, we expect that LFP batteries will account for around 55-60% of the total EV battery market in India. The demand for LFP batteries is projected to reach USD 4-5 billion by then. So, this is a technology that’s here to stay.

How Indian EV Manufacturers Are Adopting LFP Batteries

Most of the big names in the Indian EV market are making the switch to LFP batteries. The reasons are clear—LFP batteries are cheaper, safer, and have a longer lifespan, which is exactly what manufacturers are looking for in urban and short-range electric vehicles.

Let me give you a few examples:

Tata Motors, India’s largest EV maker, has been quick to adopt LFP batteries. Their popular models like the Tata Nexon EV and the Tiago EV now use LFP cells. When they made the switch from NMC to LFP, they were able to reduce the cost of the Nexon EV by about 20%, while also improving safety and extending the battery’s life cycle.

Ola Electric, which dominates the electric scooter market, uses LFP batteries in all their models, including the Ola S1 and S1 Pro. Their factory in Tamil Nadu, which is the largest two-wheeler EV factory in the world, is heavily invested in producing LFP battery packs for their entire scooter lineup.

Mahindra Electric has also announced plans to include LFP batteries in their upcoming electric SUVs and three-wheelers. For Mahindra, the main goal is to keep costs low while ensuring that their vehicles are reliable for Indian road conditions.

Hero Electric, a leader in the two-wheeler market, has adopted LFP batteries across its range of electric scooters. Their focus on affordability and durability makes LFP a natural fit.

Even Ather Energy, which is known for its premium electric scooters, has switched to LFP batteries for their Ather 450X model. For them, this shift aligns with what Indian consumers value most—safety and long-lasting performance.

Beyond personal vehicles, LFP batteries are also making their way into public transportation. Cities like Delhi, Mumbai, and Bangalore are using electric buses powered by LFP batteries. These buses, made by companies like Olectra Greentech and Ashok Leyland, benefit from the longer lifespan and better safety features of LFP technology.

Why LFP is Becoming the Preferred Choice for Indian EVs

So, why are Indian manufacturers moving toward LFP batteries? There are several reasons:

(i) Cost Efficiency: LFP batteries don’t rely on cobalt or nickel, which are both expensive and subject to supply chain disruptions. This makes LFP batteries cheaper to produce, which is a huge plus for a price-sensitive market like India. Tata Motors, for example, cut the price of their EVs by nearly 15% by switching to LFP.

(ii) Safety: LFP batteries are inherently safer. They’re less likely to overheat, which is a big concern in India’s hot climate. As EVs become more common, especially in public transportation, safety is becoming a top priority.

(iii) Longevity: While LFP batteries may have slightly less energy density than NMC batteries, they last longer. This is a huge benefit for fleet operators and public transport systems, where vehicles are used frequently. LFP batteries can handle up to 4,000 charge cycles, which is way more than the 1,500-2,000 cycles you get with NMC.

(iv) Sustainability: India has abundant reserves of iron and phosphate, which are the key materials used in LFP batteries. This makes LFP easier to produce locally, reducing the need for costly imports and supporting the government’s “Make in India” initiative.

Challenges and Opportunities for LFP in India

Of course, there are still some challenges with LFP batteries. Their energy density is lower than NMC batteries, which means vehicles using LFP might not have the same range. But for most Indian drivers, who don’t travel long distances daily, and with more charging stations coming up, this isn’t a huge issue.

India will also need to ramp up its battery production and charging infrastructure to fully support the widespread adoption of LFP. Thankfully, government initiatives like the Production-Linked Incentive (PLI) scheme are helping to boost local manufacturing.

On the flip side, the ongoing development of LFP technology—especially improvements in energy density and cost reduction—presents a huge opportunity. India could become a global hub for battery production, which would be a massive boost for our economy.

        Lithium Battery Pack: Type, Designing, Safety and Performance

        Lithium battery pack designing is a topic that involves many aspects, such as cell chemistry, cell configuration, battery management system, safety, and performance.

        In this blog, we will give you an overview of some of the key factors that you need to consider when designing a lithium battery pack for your electric vehicle or other applications.

        Type of Lithium Cells

        Lithium-ion batteries are made of cells that store and release energy by moving electrons and ions between two electrodes, an anode, and a cathode, through an electrolyte and a separator. The anode is the negative electrode that gives out electrons, while the cathode is the positive electrode that receives electrons. The electrolyte is a liquid or solid substance that enables the flow of ions between the electrodes. The separator is a thin membrane that keeps the electrodes from touching and causing a short circuit.

        The type of cells that you choose for your battery pack depends on your application and the characteristics that you want your battery pack to have.

        Different types of cells have different pros and cons in terms of energy density, power density, cycle life, safety, cost, and environmental impact.

        Lithium cobalt oxide (LCO): This is one of the most widely used types of cells for consumer electronics, such as laptops and smartphones. It has a high energy density, but a low power density and a short cycle life. It is also very sensitive to overcharging or damage and can cause thermal runaway and fire.

        Lithium manganese oxide (LMO): This is a safer and cheaper alternative to LCO but with a lower energy density and a higher self-discharge rate. It is often used for power tools and electric bikes.

        Lithium nickel manganese cobalt oxide (NMC): This is a popular type of cell for electric vehicles, as it offers a good balance of energy density, power density, cycle life, and safety. It is also more stable and less expensive than LCO.

        Lithium iron phosphate (LFP): This is a very safe and long-lasting type of cell but with a low energy density and a high weight. It is suitable for applications that require high power and long cycle life, such as stationary energy storage and electric buses.

        Lithium nickel cobalt aluminum oxide (NCA): This is a high-performance type of cell that has a high energy density and a high power density, but a low cycle life and a high cost. It is mainly used by Tesla for its electric vehicles.

        Lithium titanate (LTO): This is a unique type of cell that has a very high power density and a very long cycle life, but a very low energy density and a very high cost. It is ideal for applications that require fast charging and high power, such as electric buses and grid storage.

        Cell configuration

        Once you have chosen the cell chemistry, you need to decide how to arrange the cells in the battery pack. The cell configuration determines the voltage, capacity, and current of the battery pack. There are two ways to connect the cells: in series or parallel.

        Series connection: This means connecting the positive terminal of one cell to the negative terminal of another cell. This increases the voltage of the battery pack but keeps the capacity and current the same as a single cell. For example, if you connect four 3.6 V cells in series, you get a 14.4 V battery pack with the same capacity and current as one cell.

        Parallel connection: This means connecting the positive terminals of multiple cells, and the negative terminals of multiple cells. This increases the capacity and current of the battery pack but keeps the voltage the same as a single cell. For example, if you connect four 3.6 V cells in parallel, you get a 3.6 V battery pack with four times the capacity and current of one cell.

        You can also combine series and parallel connections to achieve the desired voltage, capacity, and current of the battery pack. For example, if you connect four 3.6 V cells in series, and then connect four of these series strings in parallel, you get a 14.4 V battery pack with four times the capacity and current as one cell.

        The cell configuration also affects the size, weight, and shape of the battery pack. You need to consider the available space, the mechanical strength, and the thermal management of the battery pack when designing the cell configuration.

        Safety among Lithium Batteries

        Safety is the most important aspect of lithium battery pack designing, as lithium-ion batteries can pose a fire and explosion hazard if not handled properly. Several factors can cause a lithium-ion battery to fail, such as:

        ·   Manufacturing defects, such as impurities, cracks, or metal particles in the cells

        ·   Mechanical damage, such as punctures, crushes, or drops

        ·   Electrical abuse, such as overcharging, over-discharging, short circuit, or reverse polarity

        ·   Thermal abuse, such as overheating, overcooling, or exposure to fire

        ·   Environmental factors, such as humidity, pressure, or vibration

        To prevent or mitigate these risks, you need to follow some best practices when designing a lithium battery pack, such as:

        ·   Choosing a suitable cell chemistry that matches the application and the safety requirements

        ·   Using high-quality cells from reputable manufacturers that have passed rigorous testing and certification

        ·   Designing a robust cell configuration that can withstand mechanical and thermal stress

        ·   Incorporating a reliable BMS that can monitor and protect the battery pack from electrical and thermal abuse

        ·   Adding safety features, such as fuses, circuit breakers, diodes, switches, vents, and flame retardants

        ·   Testing and validating the battery pack under various conditions and scenarios

        ·   Following the standards and regulations for lithium battery pack design, transportation, and disposal

        Performance of Lithium batteries

        Performance is another important aspect of lithium battery pack design, as it determines the functionality and efficiency of the battery pack. Several parameters measure the performance of a lithium battery pack, such as:

        ·   Energy density: This is the amount of energy stored per unit volume or weight of the battery pack. It affects the range and endurance of the battery pack. The higher the energy density, the longer the battery pack can run.

        ·   Power density: This is the amount of power delivered per unit volume or weight of the battery pack. It affects the speed and acceleration of the battery pack. The higher the power density, the faster the battery pack can operate.

        ·   Cycle life: This is the number of times the battery pack can be charged and discharged before its capacity drops below a certain threshold. It affects the lifespan and durability of the battery pack. The longer the cycle life, the more the battery pack can be used.

        ·   Charge and discharge rate: This is the speed at which the battery pack can be charged and discharged. It affects the convenience and flexibility of the battery pack. The faster the charge and discharge rate, the less time the battery pack needs to be plugged in or out.

        Phase change materials are substances that undergo a phase transition, typically from solid to liquid, in response to temperature changes. These materials have high latent heat capacities, meaning they can absorb and release a significant amount of heat during the phase transition without experiencing a substantial temperature change. PCMs are often integrated into battery packs as passive heat absorbers. When the temperature inside the battery pack increases, the PCM absorbs heat and undergoes a phase transition, effectively moderating the temperature rise within the battery.

        Advantages of Phase Change Materials:

        1. High Heat Absorption: PCMs can absorb and release large amounts of heat during phase transitions, helping to regulate battery temperature effectively.
        2. Passive Solution: PCMs do not require external power or control systems, making them simple and reliable solutions for thermal management.
        3. Uniform Temperature: PCMs distribute absorbed heat uniformly, preventing hotspots within the battery pack.

        Distinguishing Factors:

        While both potting materials and phase change materials offer unique benefits, their differences lie in their primary functions and applicability:

        1. Objective: Potting materials focus on insulation and protection, while PCMs primarily address heat absorption and temperature moderation.
        2. Active vs. Passive: Potting materials provide a barrier to heat transfer, requiring an external heat dissipation mechanism. In contrast, PCMs passively absorb and release heat through phase transitions.
        3. Complexity: Potting materials may involve complex encapsulation processes while integrating PCMs can be relatively straightforward.
        4. Environmental Factors: Potting materials offer better protection against environmental elements, such as moisture and dust. PCMs are more suitable for internal temperature regulation.

        In conclusion, potting and phase change materials contribute to efficient thermal management in lithium-ion batteries, but they serve distinct purposes. Potting materials are geared towards insulation and protection, making them suitable for extreme environmental conditions. On the other hand, phase change materials provide passive heat absorption, maintaining uniform temperatures within the battery pack. The choice between these methods depends on the specific requirements of the battery application, with a consideration of factors such as battery design, operating conditions, and the desired thermal management goals.

        Lithium-ion battery storage demand in India: New policies and challenges

        Lithium-ion battery storage demand in India: New policies and challenges

        Lithium-ion batteries (LiBs) are a very important technology for electrifying transportation and integrating renewable energy sources into the power system. In comparison to other battery technologies, LiBs feature a high energy density, a long cycle life, and minimal maintenance costs. However, they also pose environmental and societal concerns, including raw material extraction, used battery recycling, and the safety and security of battery storage systems.

        India is one of the fastest-growing LiB markets, owing to rising demand for portable devices, electric vehicles (EVs), and stationary energy storage applications. According to a report by McKinsey and the Global Battery Alliance (GBA), India’s LiB demand is predicted to rise from 3 GWh in 2020 to 20 GWh by 2026 and 70 GWh by 2030, with automotive applications accounting for 90% of overall LiB demand1. Annual capacity additions for LiBs for automotive applications are estimated to rise from 2.3 GWh in FY2021 to 104 GWh by FY2030.

        To address this rising demand, India must build a strong and sustainable LiB manufacturing ecosystem capable of competing with global firms while also ensuring energy security and self-sufficiency. However, India lacks adequate domestic production capacity, raw material supply, recycling infrastructure, and regulatory support for LiB manufacturing at the moment. 

        According to an IEEFA estimate, India’s domestic LiB production capacity in 2020 was only 1.5 GWh, meeting less than half of local demand. India also imported more than 90% of its LiB raw materials from China, Australia, Chile, and South Africa, including lithium, cobalt, nickel, and manganese. Furthermore, as of 2020, India had no established recycling policy or infrastructure for LiBs.

        To solve these issues and capitalize on the opportunities presented by LiB manufacturing, India must implement a comprehensive and proactive policy framework that spans the entire value chain, from mining to recycling. 

        Some of the key policy initiatives that India is planning or implementing are:

        • The NITI Aayog created the National Mission on Transformative Mobility and Battery Storage (NMTMBS) in 2019 to promote clean and sustainable mobility solutions and establish a phased manufacturing program for LiBs and EVs. The program aims to establish 50 GWh of LiB production capacity by 2025 via a network of gigafactories spread across India.
        • The Cabinet approved the Production Linked Incentive (PLI) scheme for advanced chemistry cell (ACC) battery manufacturing in May 2021, which provides incentives worth Rs 18,100 crore ($2.4 billion) over five years to domestic and foreign manufacturers who invest in setting up ACC battery plants in India. The plan aims to produce 50 GWh of ACC battery capacity by 2025-26.
        • The Draft National Energy Storage Mission (NESM), released by the Ministry of New and Renewable Energy (MNRE) in 2018, aims to create an enabling policy framework for energy storage deployment in India. The mission focuses on four key areas: research and development, manufacturing and supply chain development, deployment and end-use applications, and policy and regulatory support.
        • The Ministry of Environment, Forests, and Climate Change (MoEFCC) announced the Draught Battery Waste Management Rules (BWMR) in 2020, proposing to govern the collecting, transportation, storage, recycling, disposal, and import of used batteries in India. The laws require that every battery maker or importer collect at least 70% of their spent batteries for recycling or safe disposal.

        These policy initiatives are expected to boost the domestic LiB manufacturing industry and create a conducive environment for innovation and investment. However, there are still some challenges that need to be addressed to realize the full potential of LiB manufacturing in India. 

        Some of these are:

        Raw material availability and affordability:  India has limited deposits of crucial raw materials for LiBs, including lithium and cobalt, which are mostly concentrated in China, Australia, Chile, and South Africa. Although significant lithium reserves have recently been identified in Jammu & Kashmir, they are insufficient to supply domestic demand. India must establish long-term supply arrangements with foreign suppliers, diversify its import sources, and investigate other resources that can minimize its reliance on lithium and cobalt.

        Recycling technology development and adoption:  Recycling LiBs can help to lessen the environmental impact of battery waste while also recovering valuable elements that can be reused in the creation of new batteries. However, as of 20202, India lacks a clear recycling policy and infrastructure for LiBs. The Draught Battery Waste Management Rules (BWMR) intend to govern used battery collecting and recycling in India, but they must be finalized and properly enforced. India must also develop and implement cost-effective and efficient recycling systems capable of recovering high-purity materials from LiBs.

        Battery technology innovation and standardization: In terms of performance, safety, durability, and affordability, LiBs are always evolving. To keep up with global trends and fulfill the special needs of the Indian market, India must engage in research and development (R&D) and innovation. India must also develop quality standards and testing processes for LiBs to assure their dependability and interoperability across various applications and platforms.

        Battery storage system integration and management: By providing auxiliary services, peak shaving, load shifting, and renewable integration, LiBs can significantly improve the stability and flexibility of the electricity system. However, LiBs present grid operators with technical and operational hurdles, such as power quality issues, bidirectional power flows, cybersecurity hazards, and demand response management. India must develop and deploy smart grid technology and regulations that will allow for the most efficient integration and administration of battery storage systems in the power system.

        LiB production provides India with a strategic chance to speed up its renewable energy transition while also creating economic benefits. To address the numerous value chain concerns, however, a comprehensive and coordinated policy framework is required. India should use its capabilities in IT, engineering, and manufacturing to build a competitive and sustainable LiB business that can meet domestic demand while also tapping into the global market.

        Why companies are moving towards LFP batteries?

        Why companies are moving towards LFP batteries?

        A LFP battery is a type of lithium ion battery that has a cathode made of lithium iron phosphate (LiFePO4) and an anode made of carbon. The LiFePO4 battery has no nickel or cobalt, the raw material supply is more constant, and it has a greater cost advantage than ternary lithium batteries.

        LiFePO4 batteries have gained popularity in recent years due to their benefits of long cycle life, good safety performance, high stability, and inexpensive cost. Tesla, BYD, Volkswagen, Tesla, Ford, Toyota, and a slew of other automakers have stated that they have or are exploring using lithium iron phosphate batteries into new vehicles.

        In 2025, LiFePO4 batteries are expected to account for 36% of the batteries used in pure electric vehicles. However, in terms of cruising range, energy density, and low temperature tolerance, lithium iron phosphate batteries are marginally inferior to ternary batteries.

        Globally companies are focusing on LFP Batteries

        Globally, China’s LiFePO4 battery technology is at the forefront. China has made significant investments in the advancement of battery technology. Over the last decade, Chinese companies have aggressively promoted LiFePO4 batteries as an alternative to the more popular nickel-cobalt-manganese ternary batteries in the West.

        When European and American companies abandoned lithium iron phosphate technology, some Chinese battery companies spent ten years researching it, improving the energy density of batteries and systems, and making it the mainstream technology route for low-end and mid-range models.

        In comparison to other countries, China’s LiFePO4 battery technology has consistently achieved advancements and has greater benefits. China’s LiFePO4 battery technology has advanced significantly in the last two years. BYD, for example, introduced the blade battery, which not only retains the safety benefits of lithium iron phosphate materials but also compensates for energy density inadequacies with CTP technology. It is a product with all-around performance.

        China dominance of LFP Batteries

        Majority of the world’s lithium iron phosphate manufacturing capacity is currently located in China. With a steady increase in demand in international markets over the last two years, China’s lithium iron phosphate goods have been gradually deployed through export and local factory construction. It is a fantastic chance for China to supply lithium iron phosphate battery goods and materials to other countries.

        Companies can use China’s lithium iron phosphate sector to secure global clients. Even if they eventually switch to the ternary method, this supply channel will help to develop the worldwide market. According to available data, China dominates LiFePO4 battery production and will account for 99.5% of world supply this year. China’s LiFePO4 battery production capacity is expected to account for 97% of global planned production capacity by 2030.

        LFP Market Share to increase

        The installed capacity of lithium iron phosphate battery technology in the international market is predicted to grow further due to constant innovation and development. The installed capacity of lithium iron phosphate batteries has officially surpassed that of ternary batteries, according to China’s power battery pattern.

        According to relevant research institutions, lithium iron phosphate batteries rely on their cost-effective advantages, and with continuous technological advancement, the installed capacity of lithium iron phosphate batteries is expected to exceed 60% in the global power battery market in 2024.

        Another point of view stated that there is still a lot of room for development in the energy density of lithium iron phosphate batteries with additional optimisation of the material system and process in the future. In this context, relevant Chinese enterprises have launched phosphoric acid material system battery products with higher energy density and improved low-temperature performance, such as lithium manganese iron phosphate.

        What is C Rating in Lithium Battery?

        What is C Rating in Lithium Battery?

        The c rate is commonly used to calculate a battery’s charge and discharge rate. The c rate is a standard used to determine the magnitude of the battery charge and discharge current, as well as to anticipate the battery charge and discharge time.

        Depending on the battery type and the application environment, different batteries have varied c rates; the majority of batteries are rated at 0.2C. That is, a 1000mAh battery discharged at a 0.2c rate for five hours would produce 1000mA. A similar type of battery discharging at 0.5C would provide 500mA for 120 minutes.

        In layman’s terms, it shows the battery’s charge and discharge rates. A battery with a c rate is divided into two rates: discharge and charge. The purpose of the c rate battery is to specify how long it takes for a battery to drain after it has been fully charged. A 10 C battery will discharge in 6 minutes, a 2 C battery in 30 minutes, and a 1 C battery in 60 minutes.

        C rating on a lithium battery

        A lithium-ion battery’s C rating is an important characteristic that influences its performance in high-drain applications such as electric automobiles, power tools, and drones. A higher C rating indicates that the battery can supply more current and power, making it appropriate for high-performance applications requiring rapid acceleration or continuous power output.

        How to calculate C rating of Lithium Batteries?

        To calculate a lithium-ion battery’s maximum discharge current, you must first know its capacity (C), rated voltage (V), and C rating (C). The following is the formula:

        Capacity (C) x C Rating (C) / Rated Voltage (V) = Maximum Discharge Current

        Take, for example, a 200Ah lithium-ion battery with a 2C rating and a rated voltage of 51.2V. The maximum discharge current is:

        Maximum Discharge Current = 200Ah multiplied by 2 / 51.2V = 78.125A

        This means that the battery can deliver a maximum current of 78.125A without being damaged or having its lifespan reduced.

        A higher c-rated battery allows the battery to operate with less voltage drop. When the battery’s voltage can withstand greater voltages, the current rate must likewise double.

        Varied application scenarios have varied battery c rate needs. Power batteries that must drive motors have greater c-rate requirements, whereas energy storage batteries used in solar energy storage systems prioritize battery capacity requirements.

        Factors affecting C Rating of the batteries

        The impact of the ambient temperature limits the majority of lithium-ion18650 c rate. Temperatures that are too high or too low will have an effect on the battery’s c rate. If the battery is exposed to high temperatures for an extended period of time, its cycle life may be reduced. Furthermore, if the temperature is too low, the battery c rate will suffer. The following are the primary factors influencing battery c rate:

        • Temperature: Lithium-ion batteries are temperature sensitive, and extreme heat or cold can degrade their performance. High temperatures can raise the internal resistance of the battery, diminish its capacity, and shorten its cycle life. Low temperatures, on the other hand, might reduce the discharge rate of the battery and increase its internal resistance, lowering its overall performance. As a result, it’s critical to select a battery with a C rating appropriate for the application’s temperature range.
        • State of Charge: A lithium-ion battery’s C rating can also vary based on its state of charge (SOC). Because of its higher voltage, a fully charged battery can supply more current than a partially charged battery. As a result, when selecting a proper C rating for the application, it is critical to consider the battery’s SOC.
        • A lithium-ion battery’s C rating might degrade over time due to ageing and wear. As the battery is charged and discharged repeatedly, its internal resistance develops, decreasing its ability to supply high power.

        High C Rating Benifits

        • High C-rating batteries can produce a significant amount of power quickly, making them ideal for high-performance applications requiring rapid acceleration or continuous power production.
        • High C rating batteries have lower internal resistance than low C rating batteries, which reduces voltage drop and improves battery efficiency.
        • Because of their high power output, high C rating batteries may be charged quickly, minimising charging time and enhancing battery convenience.

        Why LMFP is better than LFP and NMC?

        Why LMFP is better than LFP and NMC?

        Because of their high energy density, long cycle life, and low self-discharge rate, lithium-ion batteries have become the leading energy storage I. technology. The cathode material selected is critical in influencing the overall performance of the battery. This research examines the cathode materials LMFP, LFP, and NMC, emphasizing the merits of LMFP and why it should be considered the ideal choice for lithium-ion battery applications. 

        In this article, we will explore why LMFP batteries are better than NMC and LFP, especially for the Indian climatic conditions.

        Why LMFP is better than LFP and NMC?

        • Cathode Material crystal structure 

        The olivine structure of LMFP and LA’ cathodes provides great thermal stability, long cycle life, and strong safety properties. NMC cathodes, on the other hand, have a layered structure that offers high &clergy density and decent rate capability but may have weaker thermal stability and shorter cycle life. 

         

        • Energy density and electrochemical properties 

        The operating voltage of LMFP is greater (about 3.45V) than that of LFP (approximately 3.2V), resulting in a higher energy density (120-140 Wh/kg for LMFP vs. 9 110 Wh/kg for LA”). This is because manganese is added, which boosts electrical conductivity and lithium-ion diffusion in LMFP. In contrast, NMC has a higher energy density (150-220 Wh/kg) and operating voltage (3.6-3.7V). 

         

        • Rate capability 

        Manganese substitution in LMFP improves lithium-ion diffusion, resulting in higher rate capability compared to LFP. As a result, LMFP is well-suited for high-power applications such as fast-charging electric vehicles and power equipment. Because of its layered structure, which allows for two-dimensional lithium-ion diffusion, NMC also has good rate capability. 

         

        • Thermal stability

        LMFP retains the thermal stability and safety properties of LFP, with a thermal runaway point above 250°C, making it a safer option than some high-energy-density chemistries such as NMC, which has a thermal runaway point of around 200-210°C. 

         

        • Cost & environmental impact

        Because iron and manganese are less expensive than cobalt and nickel, LMFP may be more cost-effective than NMC. Furthermore, LMFP is cobalt-free, addressing ethical and environmental concerns about cobalt mining while minimizing reliance on this limited resource. 

         

        • Performance in India

        The strong thermal stability of lithium manganese iron phosphate makes it a good candidate for Indian temperature conditions, which might be characterised by high ambient temperatures. Its thermal runaway point of more than 250°C delivers good safety performance in the high-temperature environment of India. 

        What are LMFP Batteries?

        LMFP based Rugpro battery, a new kid on the block

        LMFP-based Rugpro battery, a new kid on the block

        When the Indian market asked for a better and improved lithium battery, we at Ipower Batteries answered that call with our new series of lithium batteries. We present you Rugpro, an LMFP chemistry-based lithium battery specifically for Indian market needs. Let’s have a look at this new chemistry and try to understand how it’s better than others.

        As an improved form of lithium iron phosphate (LFP), lithium manganese iron phosphate (LMFP) is emerging as a new power battery hotspot. Automakers, battery manufacturers, and cathode active material manufacturers are all expanding their footprints in this industry.

        Lithium manganese iron phosphate has the same structure as lithium iron phosphate and is a combination of lithium iron phosphate and lithium manganese phosphate. As a result, lithium manganese iron phosphate has the same advantages as lithium iron phosphate, such as low cost, high safety performance, high thermal stability, no self-ignition due to acupuncture and overcharging, long cycle life, no risk of explosion, compensation for LFP’s disadvantages.

        Furthermore, when compared to lithium iron phosphate, lithium manganese iron phosphate performs better at low temperatures. According to Huajin Securities, lithium manganese iron phosphate has a capacity retention rate of 75% at -20°C, while lithium iron phosphate has a capacity retention rate of 60%-70%.

        Advantages of LMFP:
        Only LMFP can match the specific capacity of LiFePO4 (170mAh/g), but its voltage platform is only 3.4 V, whereas lithium manganese iron phosphate can reach 4.1 V due to the higher redox potential of manganese ions Mn3+/Mn2+, increasing the energy density of LMFP by 15 to 20% at the same specific capacity.

        LMFP has greater low-temperature performance than LFP, which has poor low-temperature performance with a capacity retention rate of 60-70% at -20°C, but LMFP has a capacity retention rate of around 75% at -20°C.

        The olivine structure of LMFP makes it more stable and safer than ternary materials with layered structures. The tetrahedral PO43- anion’s strong covalent P-O interactions stabilize the oxygen atom and limit oxygen loss, making LMFP more stable while charging and discharging. However, because the manganese element has low high-temperature performance, the safety performance of LMFP is slightly worse than that of LFP, yet both are deemed safer than ternary material.

        The cycle performance of both LFP and LMFP is better than that of ternary because of the high lattice stability of the olivine structure type. The tetrahedral PO43- anion’s strong covalent P-O interactions extend the cycle life, limit oxygen loss, and allow Li+ to be extracted/embedded in a stable crystal structure.

        LMFP vs LFP

        Higher energy density: Because LMFP has a higher working voltage (about 3.45V) than LFP (approximately 3.2V), it has a higher energy density (roughly 120-140 Wh/kg vs. 90-110 Wh/kg for LFP). This enables batteries with longer runtimes and higher capacity.

        Better rate capability: The manganese substitution in the LMFP structure improves lithium-ion diffusion, resulting in better rate capability. As a result, LMFP is well-suited for high-power applications such as fast-charging electric vehicles or power tools, which are in high demand in India.

        Thermal stability and safety are comparable: LMFP retains the thermal stability and safety features of LFP, making it a safer option when compared to some high-energy-density chemistries such as NMC.

        The thermal runaway point of the LMFP is above 250°C, similar to that of the LFP, offering good safety performance in India.

        LMFP vs NMC

        LMFP has various advantages over the typical NMC chemistry for Indian temperature conditions:

        Enhanced thermal stability: The olivine structure of the LMFP is more thermally stable than the layered structure of the NMC, lowering the risk of thermal runaway and enhancing safety performance. NMC has a lower thermal runaway point than LMFP, making LMFP a safer choice in India’s high-temperature climate.

        Cobalt-free: Unlike NMC, LMFP is cobalt-free, addressing ethical and environmental concerns about cobalt mining while lowering reliance on this limited material.

        Cost-effectiveness: Because LMFP contains iron and manganese, it may be less expensive than NMC, which contains more expensive metals such as cobalt and nickel.

        The growing market of Electric Vehicles in India

        In recent years, there has been a substantial increase in the use of electric vehicles (EVs) in India. Because India is a major consumer of fossil fuels, the change to electric vehicles has multiple advantages for the environment, energy security, and the economy. In this blog article, we will look at the technological and legal implications of the EV boom in India.
        Several technical considerations, including advancements in battery technology, charging infrastructure, and government incentives, have contributed to India’s shift towards EVs.

        Do you  know, Ipower Batteries have AIS 156 Phase 2 certificate for all of its batteries including LFP and NMC 

         

        Join the EV-Revolution with Ipower Batteries

        All the test that batteries goes through for AIS 156 Phase 2 Certificate

        Ipower Batteries has secured the AIS 156 phase 2 certificate for both its NMC and LFP batteries. Now all of the batteries in these two chemistries are AIS 156 phase 2 certified as required by the government of India.

        Now let’s understand the importance of this certificate and why it’s a big milestone for a battery manufacturer.

        We all know that AIS 156 amendments came into the picture because of various fire incidents with EVs last summer. So the government of India set a parameter for the battery manufacturers with enhanced safety features. The battery manufacturers were asked to get their batteries tested on various factors before getting the certificate and selling it into the market.

        Following were those tests.

        • IP67: (Waterproof batteries)
          IP67 test certifies that the batteries are waterproof, now the question is why it is required.
          Well in India, most of us are used to washing and cleaning our vehicles using water and if we go a little bit into the chemistry, the lithium plus water is an explosive reaction. The battery needs to be waterproof otherwise it will become a serious threat to the rider. Making a battery waterproof is not a simple task, only those can do who manufacture the batteries, not the ones who just procure them from 3rd party.

         

        • Thermal runaway:
          Charging and discharging the battery is an exothermic process. It means heat is generated when you ride the electric vehicle or charge it. As we know the entire battery pack, and the case is waterproof and airtight, and that heat will generate pressure which can lead to an explosive reaction. To counter that, the battery needs to have a heat sink, in short, a way to transfer that heat out of the battery is required. There are various ways to do that like having an active or passive cooling process. The batteries are required to have thermal runaway.

         

        • Vibration test:
          Believe it or not, it’s a very important test. If you drive your vehicle either a two-wheeler or a three-wheeler, you know the conditions of the Indian roads and how they impact your vehicle. The same goes for lithium batteries. Indian roads are full of post-hols, non-symmetrical speed breakers, and animals roaming around freely. Every time you put brakes, batteries are subjected to sudden vibration due to the law of inertia and after some time, it can damage the physical structure of the battery. To insure that does not happen, batteries are subjected to vibration tests.

         

        • BMS Test:
          BMS is the most important part of the batteries. They provide all sorts of data that is required for the safety of the batteries. BMS makes sure if there is something unusual happening with the battery like it’s getting heated more than normal then it will not only inform the raider but also will take the necessary precautionary measures. There are two types of BMS, communicative and non-communicative. The new batteries under the AIS 156 phase 2 need to have the communicative BMS that our batteries have.

         

        • CAN Protocol:
          With batteries, we get chargers but India is a country of jugad. If the charger provided by the company will stop working due to any reason, we will try to use a non-authorized charger or non-authorized charging method that can lead to accidents with the batteries. You have to understand, lithium batteries are power-packed boxes with the potential to cause serious damage to the property and the personnel if not handled with care. With the CAN protocol, it is ensured that batteries will be charged with an authorized charger and authorized methods.

         

        • Pressure valve:
          As discussed earlier, the heat generated in the battery will create air pressure in the battery pack that needs to be released if goes above a certain level. The new batteries have a pressure valve that works exactly like the pressure valves in the pressure cookers.

        These are those tests, that are mandatory to get the AIS 156 phase 2 certificate. The beauty of these tests is that only those who have the capability of building the battery packs in-house can pass.

        It means, with this AIS 156 certificate, the government is filtering the market and allowing only those who can build safer batteries.

        We at Ipower Batteries proudly say that we are in an elite group of battery manufacturers who are committed to taking the industry forward by providing safer and long-lasting batteries.

        Why do EV batteries catch fire?

        In the previous article we had an overview of how to protect your lithium batteries from catching fire, but it is also important to know how and why lithium batteries catch fire. Here in this article we will explore the same.

        Why do EV batteries catch fire?

        Thermal runaway occurs when lithium-ion cells reach several hundred degrees Celsius (the fires you see are the result of thermal runaway). Most current batteries shut off automatically around 45-55°C. Even if these safeguards are not taken, it is not possible to heat the battery to a few hundred degrees Celsius solely by using ambient heat or heat created by the batteries.

        Short circuits are the reason of 99% of battery fires. As a result, the temperature of the cell rises by a few hundred degrees Celsius, resulting in thermal runaway.

        Short circuits happen for three reasons: ‍

        • Poor cell quality
        • Poor design of the battery
        • Poor BMS

        Internal short-circuiting can occur as a result of poor cell quality. This happens when the anode and cathode are accidentally linked inside due to design flaws, short-circuiting the normal current route. This finally leads to uncontrolled current. It becomes the cause of Thermal Runaway.

        Short-circuiting is not usually caused by poor cell quality. The design of battery packing has a significant impact on safety. Packaging relates to how cells are assembled, as well as how they are electrically connected and mechanically held together.

        Poor BMS  leads to Overcharging

        Cells cycle between lower and higher threshold voltages, which generally correspond to the 0% and 100% states of charge.

        LFP voltage ranges from 2.8V to 3.6V.

        NMC voltage ranges from 2.8V to 4.2V.

        Even a 0.05V overcharge of NMC can significantly enhance the growth of Lithium dendrites.

        Overcharging causes cells to swell, collide, short-circuit, and eventually catch fire. It’s dramatic, and you don’t have to make it up.

        How Ipower Batteries is solving all these issues?

        Ipower Batteries have AIS 156 Phase 2 certificate for all of its batteries including LFP and NMC based batteries. Getting an AIS 156 Phase 2 certification is very though but thats for next article.

        How to avoid lithium battery fire this summer?

         

        Last summer we saw a lot of news of EVs catching fire. Electric scooter sales have risen in recent years, but a string of fires has cast a pall over the potential business.

        This raises a lot of questions related to battery safety and battery manufacturing. Here we would explore how you as an EV user can keep your battery safe in this summer that has arrived. 

        The largest, most expensive, and most significant component of your electric vehicle is the battery. It is the driving force for electric automobiles. The Indian climate and driving conditions are tough, therefore it’s vital that you thoroughly understand battery care and charging requirements.

        Here are some recommendations for keeping your electric scooter safe and extending battery life:

        Thermal Management in the battery

        Lithium-Ion Battery Thermal Runaway: What's the Big Deal?

        • Thermal management in an EV battery is critical since it must operate in extremely cold or extremely high temperatures. 
        • Protect your vehicle and batteries against high temperatures. Make sure you don’t leave your EV parked in the blazing sun or the cold for extended periods. 
        • Place your electric vehicle in the shade or plug it in so that its thermal management system operates solely on grid power and maintains a constant range of temperatures while in operation. 
        • For certain battery types, only use genuine and authentic chargers.
        • Pay attention to the battery type, as some batteries catch fire easily. You may need to charge them or park them away from flammable materials. 
        • Do not swap or use any non-genuine chargers. -Maintain batteries at ambient temperature.
        • Please do not charge batteries for more than one hour after they have been used. It is best to allow the batteries to cool down before charging them. 
        • If you discover that the battery shell has been broken or that water has entered the battery, immediately isolate and store it separately, and notify your dealer.
        • The battery and charger should be stored in a clean, dry, and ventilated location, away from corrosive compounds, at least 2 meters away from fire and heat sources, away from combustible substances, and disconnected from the battery. 
        • If you observe the lithium-ion battery overheating while charging, consider relocating the device away from flammable materials and switching off the current supply.

        Periodically check your vehicle batteries.

        Unlike in gasoline vehicles, battery levels may deplete if an electric vehicle is stored and not used for an extended period. So, constantly keep track of when you last charged it. 

        Avoid leaving batteries totally charged or completely depleted. 

        Keep it between 20 and 80%. Whenever feasible, keep your battery’s state of charge between 20% and 80%. Charging the battery to full over and again will cause it to degrade faster. 

        Only charge fully for long trips 

        Make frequent, brief trips in your automobile. Do not let your car idle for long periods. It’s excellent for the vehicle’s overall health, just like it is for petrol or diesel cars, to take it for a trip now and then.

        What is Battery Management System and why lithium Battery Needs it?

        What is Battery Management System and why lithium Battery Needs it?

         

        The winter of EVs is on its way and it’s called the summer season. Last year we saw various EVs and battery stations catching fire. When the government did the analysis, it was found that most of the batteries didn’t have any safety measures. So the government introduced AIS 156 amendments that mentioned smart batteries or batteries with BMS. But the question is what is BMS and why does your lithium battery need it?

        What is BMS?

        A BMS allows for continuous monitoring, data collection, and communication to an external interface where users can view the status of each cell as well as the overall health of the battery pack. A battery management system (BMS) monitors and manages a battery pack to protect it from damage, extend its life, and keep the battery operating within its safe limits. These functions are critical for efficiency, dependability, and safety.

        Users can monitor individual cells within a battery pack using a battery management system. It is critical to maintaining stability throughout the pack as cells collaborate to release energy to the load.

         

        What does a BMS measure?

        A BMS can record data such as current, voltage, temperature, and coulomb count. Using these measurements, the system can assess the battery’s health and adjust operations as necessary to protect the pack.

        A decrease in cell voltage at a given load, for example, can indicate an increase in internal resistance. This could indicate dry-out, corrosion, plate separation, or other diagnoses.

        A sudden rise in the temperature of one cell may indicate the possibility of a thermal runaway event affecting the entire battery pack. The BMS could then stop the flow of energy and notify the user of a potential problem, allowing it to be contained before it becomes uncontrollable.

        BMS with SoC and SoH

        The state of charge (SoC) and state of health (SoH) of a battery are important indicators for determining its usability and capabilities. The SoC and SoH work together to provide a state of function, an overview of the battery, and an overview of the pack’s capabilities as a whole.

        The most straightforward and common measure that a person would come across is the state of charge. The percentages of charge on phones and laptops are the states of charge. The SoC in electric vehicle batteries is used to calculate the remaining range of the car before it needs to be recharged. This, however, is not indicative of the battery’s overall health.

        While SoC can show the battery’s short-term capability (how much energy is left), it cannot show the true capacity of the battery cell or pack. Cell capacity decreases with age, so while SoC may read 100%, the true capacity is likely to be less after a while.

        Nonetheless, SoC remains an important metric in battery management. For example, to balance the load evenly across cells within the pack, the SoC of individual cells in the battery chain must be known.

        In addition to SoC, the State of Health assesses the battery pack’s long-term capabilities.

        SoH is an estimate of how long a battery can operate optimally based on charge acceptance, internal resistance, voltage, and self-discharge. It is usually measured against a new battery cell to determine where the cell is in its lifecycle.

        There are no standard parameters for indicating SoH because it is determined by the function and applications of the battery cell. To calculate the overall SoH, different parameters such as cell resistance or self-discharge can be individually weighted.

        Because SoH is typically measured against a new cell, the BMS must keep a record of the battery’s initial conditions as well as a log of measurements throughout the battery’s lifecycle to provide a more accurate indication of battery health.

         

        Now the most important question is why BMS is so important.

        A BMS is useful not only for indicating the health of a battery but also serves to protect the battery while it is in use.

        Each battery cell and chemistry has a safe voltage, temperature, and current operating range. When a cell falls below or exceeds these limits, the BMS can detect and control it. Because lithium, for example, is a highly reactive substance, the BMS should monitor each lithium cell to ensure that it operates within predefined limits. This protects and preserves the battery in the long run.

        Cell balancing is another important safety feature of a BMS. Individual cells in a battery pack do not operate in the same way. One cell in the chain may be weaker or stronger than another, charging or discharging faster. Without proper compensation, this could harm the overall health of the pack. If one cell short circuits or fails, the stability of the entire pack suffers. Cell balancing equalizes the charge of individual cells based on their capabilities. The BMS monitors and controls the charge demanded from each cell in the chain, ensuring that SoC is distributed evenly.

        Lithium battery for e-rickshaw by Ipower Batteries


        Although lead-acid batteries are used in the majority of e-rickshaws, the market is shifting towards lithium-ion batteries. We will learn about lithium batteries for e-rickshaws in the Indian market in this article.

        Types of batteries used in e-rickshaw

        E-rickshaws are battery-powered and powered by electric motors ranging from 6500 to 1400 watts. The e-rickshaw is a cost-effective and environmentally responsible mode of transportation because of the significant savings in fuel costs. The batteries for e-rickshaws come in a variety of shapes and sizes. The batteries were designed with extended range, simple maintenance, long life, and clean air in mind. They can be obtained from a variety of sources.

         

        Lead-Acid Batteries for E Rickshaw

        The majority of e-rickshaws are powered by lead-acid batteries. They have a lower life expectancy of 360 cycles, a longer charging time of 8-10 hours, and are heavier. They have an impact on vehicle performance and longevity if they are not properly maintained because they are high-maintenance batteries.

         

        Lithium-Ion Battery for E Rickshaw– 

        Manufacturers are increasingly turning to lithium-ion batteries. They have a lower weight of around 35kg due to their high energy density, resulting in increased overall mileage. Their charging time ranges from 1.5 to 3 hours. With a life duration of 1500 cycles (NMC) and 3000 cycles, these batteries are strong, long-lasting, and effective for comfortable rides (LeFePo4). These batteries require little to no upkeep.

        Because of their superior performance, lithium-ion batteries are gradually gaining market share.

        Ipower Batteries for e-rickshaw

         

        Current status of electric rickshaw batteries in India

        The revenue from the India electric rickshaw battery market was $141.3 million in 2021, and it is expected to reach $295.4 million by 2030, at an 8.5% CAGR.

        This will be due to falling component prices, government initiatives for clean mobility, the low operating cost of electric rickshaws, and their increasing average age.

        Electric three-wheelers are becoming increasingly popular in India due to their low cost and convenience over short distances. These three-wheelers currently account for 83% of India’s EV market. Each month, approximately 11,000 new electric rickshaws are sold in India, bringing the total number to around 15 lahks. These figures could be much higher because many of them are still unregistered.

        The India electric rickshaw battery market is led by batteries with capacities less than 101 Ah, which account for more than 60% of revenue. The category will maintain its market dominance in the coming years due to consumer demand for low-cost e-rickshaws. This could also be due to the market dominance of unorganized local businesses, the majority of which produce low-cost e-three-wheeler components.

        With a 10.6% CAGR in terms of value, the contribution of batteries with capacities greater than 101 Ah is expected to grow more rapidly in the India electric rickshaw battery market. This will be due to the growing demand for e-rickshaws that can travel longer distances without needing to be recharged frequently.

        The lithium-ion battery category has a 52% market share and will contribute $196.1 million in sales by 2030. This is primarily because these variants are available in standard industry sizes, are 50-60% lighter, and have a 25-50% greater storage capacity.

         

        Factors affecting the demand for lithium batteries for e-rickshaw in India

        One of the significant trends in the Indian e-rickshaw battery market is the increasing use of e-rickshaws for logistics and mobility, as well as the batteries used in these vehicles. The country’s demand for these vehicles is growing as a result of increased activity in the e-commerce, municipal, logistics, and food and grocery sectors. In 2015, there were few electric rickshaws for logistical purposes on Indian roads; however, within two years, their share of total e-rickshaws on highways had risen to around 3%. E-rickshaws for logistics account for nearly 70% of Ahmedabad’s all-electric rickshaws.

        The rapid adoption of e-rickshaws in various cities is the primary driver of growth in the Indian e-rickshaw battery market.

        Between 2014 and 2019, the electric rickshaw market in India expanded significantly, owing to increased demand for these rickshaws, which have lower operating costs than other types of rickshaws, particularly auto-rickshaws.

        Furthermore, the government is offering incentives to encourage the widespread adoption of these environmentally friendly and cost-effective automobiles. The Indian government, for example, offers INR 50,000 incentives to five lakh e-rickshaws under the second phase of the Faster Adoption and Manufacturing of (Hybrid &) Electric Vehicles (FAME-II) scheme, which began in April 2019.

        How is the AIS 156 amendment making your batteries safe?

        How is the AIS 156 Phase 2 amendment making your batteries safe?

        Electric vehicles (EVs) are becoming more popular in India as they offer environmental and economic benefits. However, one of the main challenges for EV adoption is the safety of the batteries that power them. Batteries are complex devices that store and release energy, and they can pose risks of fire, explosion, leakage, or overheating if not properly designed, manufactured, and maintained.

        To address this issue, the Ministry of Road Transport and Highways (MoRTH) has issued an amendment to the Automotive Industry Standards (AIS) 156 and AIS 038 (Rev 2), which specify the safety requirements for EV batteries and power measurement for L-category vehicles, such as two-wheelers, three-wheelers, and quadricycles. 

        In this article, we will be exploring how AIS 156 Phase 2 is making batteries safer than ever.

        Various things in AIS 156 Phase 2 will ensure the safety of the batteries like pressure vents, active cooling systems, ev thermal management systems.


        • Pressure vents

        Pressure vents are one of the passive safety components in lithium batteries that are designed to release the internal pressure of the battery when it reaches a certain threshold. Pressure vents can prevent or mitigate the risk of fire, explosion, leakage, or overheating caused by various factors such as puncturing, overcharging, manufacturing defect, or thermal runaway.

        Pressure vents can be found in different types of lithium batteries, such as cylindrical, prismatic, or pouch cells. The shape, size, location, and opening pressure of the vents may vary depending on the battery design and specifications. Some common types of pressure vents are:

        • Pressure-sensitive vent holes: These are small holes in the metal casing of the battery that opens when the internal pressure exceeds a certain limit.
        • Bursting disc: This is a thin metal disc that is welded to the battery casing and ruptures when the internal pressure reaches a critical value.
        • Integrated safety vent: This is a vent that is incorporated into the battery terminal and consists of a spring-loaded valve that opens when the internal pressure exceeds a preset value.

        Pressure vents are important for ensuring the safety and performance of lithium batteries. However, they also have some drawbacks, such as reducing energy density, increasing the weight and cost, and allowing gas and electrolyte to escape from the battery. Therefore, it is essential to optimize the design and testing of pressure vents to balance the trade-offs between safety and efficiency.


        • Active cooling system

        An active cooling system is a type of thermal management system that uses external devices such as fans, pumps, or heat exchangers to remove heat from lithium batteries. Active cooling systems can improve the performance, safety, and lifetime of lithium batteries by maintaining the optimal temperature range and reducing the temperature gradient within and among the cells.

        Active cooling systems can be classified into two categories: air cooling and liquid cooling. Air cooling uses forced air to transfer heat from the battery surface to the ambient air. Air cooling is simple, lightweight, and inexpensive, but it has low heat transfer efficiency and may not be sufficient for high-power applications. Liquid cooling uses a circulating fluid such as water, glycol, or oil to transfer heat from the battery surface to a heat exchanger. Liquid cooling has higher heat transfer efficiency and can provide more uniform temperature distribution, but it is more complex, heavy, and costly than air cooling.

        Active cooling systems require careful design and optimization to balance the trade-offs between thermal performance and system requirements. Some of the factors that affect the design of active cooling systems are:

        • Battery geometry and configuration: The shape, size, and arrangement of the battery cells influence the heat generation and dissipation patterns and the available space for cooling devices.
        • Cooling fluid properties: The type, flow rate, temperature, and pressure of the cooling fluid affect the heat transfer coefficient and pressure drop across the battery pack.
        • Cooling device parameters: The dimensions, layout, and materials of the cooling devices such as fins, channels, pipes, or plates affect the thermal resistance and weight of the system.
        • Cooling control strategy: The timing, frequency, and intensity of the cooling operation depend on the battery’s state of charge, state of health, power demand, ambient conditions, and thermal sensors.

        Active cooling systems are often used for lithium batteries in electric vehicles (EVs) and hybrid electric vehicles (HEVs) that have high power and energy density requirements. However, active cooling systems can also be applied to other applications such as stationary energy storage systems (ESSs), portable electronics, or aerospace devices that need effective thermal management of lithium batteries.


        • Need for thermal ev management system 
          • Instead of 2, now 4 temperature sensors are required
          • Thermal pads can be used
          • Potting material can be used
          • Phase-changing material in ev thermal management can be used

        Apart from that, a fuse in the paralleling circuit must be used. String level fuse to be implemented in the lithium batteries.

        Battery Swapping Infrastructure – An Overview

        In the e-mobility sector, battery swapping is quickly becoming a superior replacement for the infrastructure for battery charging. The huge decrease in the cost of owning an electric car is one of the main factors contributing to the widespread acceptance of this technology. Sales and registration of electric vehicles without batteries are made possible by battery swapping.

        According to this concept, battery, and electric vehicles are treated as different entities and energy service providers are solely responsible for these batteries. Consequently, battery-swapping technology creates a lot of business and employment prospects in the EV ecosystem while also benefiting EV consumers.

        Battery swapping makes it simple to swap out depleted batteries for fully charged ones. In the swap stations, the batteries can be switched manually or mechanically robotically. As a result, the EV driver can substitute the drained batteries with the charged ones at any swapping station in a matter of minutes. Furthermore, because consumers only have to pay for individual swaps, this strategy is more cost-effective for them.

        Battery swapping
        Battery swapping Taken From Google / iPower doesn’t Hold Any Rights to It

        The first step in the battery swapping mechanism is to swap out depleted or partially charged batteries at the Battery Swapping Station with fully charged ones (BSS). The second task entails the Battery Charging Station’s electric recharging of the exhausted batteries (BCS).

        The order of the EV driver’s arrival at the swapping station determines how they might exchange their drained batteries. 

        The ability to self-serve conveniently is a critical feature of the battery-swapping system. This involves an efficient charging mechanism that combines simple digital authentication with seamless digital payment, making the entire process extremely simple.

        A dependable power distribution system is required for the controlled charging of multiple batteries at the same time and location. The grid system must be intelligent enough to supply high energy to the charger while also compensating for all expected fluctuations. The provision for collective charging of batteries in the same location serves as an effective load balancer for the grid. By managing the battery charging schedule accordingly, the bulk charging facility also ensures uniform load demand on the grid.

        The batteries are leased to EV drivers by energy operators. Energy providers have outlets where EV users can go when their battery is discharged and swap it for a charged battery. The batteries are owned by the energy operator, who also operates a network of battery stations where EV users are charged on a per-user basis.

        Efficient communication between the various system components is required for the smooth operation of a battery swapping operation. The battery-swapping solution employs software to ensure continuous connectivity between the vehicle, battery, driver, and chargers via cloud connectivity. This communication ensures that all of the components work together. Furthermore, all of this data is recorded and accessible to authorities as well as EV drivers to maximize the performance of the electric vehicle and its counterparts.

        The battery must be separated from the electric vehicle for each swapping operation in the swapping technology. As a result, the security of the battery is a top priority for the concerned service providers to maintain a stable business. The swappable batteries are designed as locked-smart batteries to ensure battery safety (LS- Batteries). This locking mechanism only allows an authorised charger of the energy operator to charge these batteries. Furthermore, these batteries will not be usable in any vehicle other than the one in which they are swapped.

        The battery swapping system also provides the added benefit of proper battery disposal and recycling.

        According to the study, more than 12 million tonnes of lithium-ion batteries are expected to be retired by 2030. It requires raw materials with environmental and human consequences, such as lithium, nickel, and cobalt. Batteries generate a lot of electronic waste at the end of their lives. Many industry participants are working on ways to recycle dead batteries and extract valuable metals on a large scale in order to keep materials in circulation and reduce reliance on mining. We should develop a better solution to keep the battery in use for a longer period of time in other sectors.

        Battery Swapping Roadmap

        Use standard battery technology: Battery swapping will be simplified by standard battery design elements such as pack size, cavity, electric power control unit, and output performance per unit. These innovations act as catalysts for achieving economies of scale faster.

        Recycling of EV Batteries: Battery recycling represents a significant opportunity for India. Batteries that are swapped can be built with a recycling-friendly design to make repurposing easier. Manufacturing and then recycling the batteries of these EVs with recycled materials will eliminate sourcing, lowering vehicle unit costs.

        Battery-as-a-service (BaaS): Battery should be regarded as a service segment, similar to liquefied petroleum gas or other functional batteries. To subsidise per-kilometer operations rather than the purchase cost, the incentives must be extended to battery units. Gross-cost financing models, as well as standard operating procedures for energy operators, can aid in the exploration of financially viable solutions.

        To gain the trust of users and boost confidence in availability, BaaS can be made available to them on a subscription basis.

        What is the life cycle of lithium batteries

        Lead-acid batteries have long been the “go-to” power source for gadgets, machinery, and cars. However, lithium-ion batteries are gaining acceptance across various industries due to various qualities that support efficiency and safety.

        The battery life is one of the most crucial features for a business that uses batteries in its EV fleet. An important factor in a company’s operations is the battery’s usable life. Efficiency is important when it comes to a business’s bottom line.

        In this article, we will look at the life cycle of lithium batteries and try to understand how they can outperform other batteries.

        The lengthy battery life of a lithium battery is one of its most distinguishing characteristics. Compared to typical lead-acid batteries, lithium-ion batteries have a larger capacity and can run for a lot longer on a single charge.

        Not surprisingly, lithium battery packs do not exhibit a memory effect, allowing for partial charging. As a result, they may be charged repeatedly without losing any storage capacity after being partially discharged. Top-charging your lithium-ion battery is advised rather than letting it go down to 0% before charging it.

        Depending on several variables, such as battery type and chemistry, battery size and capacity, operating environment or temperature, and charging technique, a lithium-ion battery can last anywhere between 8 hours and a few days on a full charge.

         

        What is the life cycle of lithium batteries?

        According to most manufacturers, a lithium-ion battery’s service life is 5 years or at least 2,000 charging cycles. However, a lithium-ion battery can survive up to 3,000 cycles if used and maintained properly. This is equivalent to a lead-acid battery lasting three times as long.

        When a battery’s capacity drops to 80% of its rated capacity, manufacturers often consider the battery to have reached the end of its useful life. Battery run-time will be reduced even if they can still produce usable power at less than 80% charge capacity.

        The longevity of a lithium-ion battery, however, can be impacted by several variables, including temperature, charging cycle, and charge and discharge habits.

        What are the factors that affect the life cycle of lithium batteries?

         

        Battery chemistry:

        For lithium-ion batteries, the chemical composition, or the substances and components employed in the battery besides lithium, varies. The distinct qualities of each type of lithium-ion battery affect how long it can sustain electricity. But the longest-lasting battery is the one with the best chemistry.

         

        Temperature:

        Lithium-ion batteries need to operate at an ideal temperature between 20 °C and 60 °C to function at their peak. Using this temperature range, the battery can keep 80% of its maximum capacity.

        You should anticipate decreased battery efficiency in extremely cold or hot environments because the battery needs to work harder to keep a charge.

         

        Charging Cycle:

        A device is fully charged, fully drained, and fully recharged three times throughout a charge cycle. The lifespan of your lithium battery is also dependent on how quickly you complete the charge cycle.

        A lithium battery should typically be recharged 2,000–3,000 times before losing its initial capacity. Additionally, the amount of time a battery can power a device declines as its capacity increases.

         

        How to make sure your lithium battery life last longer?

        • Avoid discharge
        • Charge your battery properly
        • Use authorized charging mediums
        • Don’t overcharge
        • Store your battery properly
        • Keep an eye on your battery capacity

        Why EV Industry needs dedicated Lithium Battery Service Centers

        Every coin has two faces, single face coins don’t exist. In the same way, any technological business has 2 aspects, one is development, and other is the servicing. Be it software or hardware, every industry needs the service industry to grow. The same goes for the EV Industry. We all know that electric vehicles have very fewer parts in comparison to ICE vehicles so the scope of services is very less (but still needed) but what about the batteries, do they need any kind of service? 

        Battery servicing, a topic which is not in the general discussion, why battery servicing is required is not a very common question. But it is going to be the question of the near future. Let us explain to you why battery servicing is important for the survival of the EV industry.

         

        In recent times, we have seen a lot of news of EV batteries catching fire due to various reasons and because of that, it’s becoming a threat to EV owners. They want to be sure that their EVs will not catch fire while it’s parked inside their homes. Also if any EV is burning, you cannot simply use water to stop it, as water with lithium can be explosive. 

        EV batteries are the powerhouse of EVs and that’s why you need to take care of them. You need experts who can analyse your batteries for any future mishap. An expert can see if the battery is getting fully charged or not. Battery manufacturers can provide all types of required servicing but most of the time, it’s a long process, from contacting them to dispatching the batteries to receiving them after it’s getting serviced. It’s a time taking process and it will impact the user of that battery economically.

         

        Let’s have an economic analysis of this process.

         

        Case 1: Single user

         

        Let’s say there is a battery manufacturer by the name XYZ which is in Delhi and an electric rickshaw owner by the name Ram who lives in Chattisgarh.

        Now Ram uses the lithium battery manufactured by XYZ company for his e-rickshaw which is his primary mode of income. He earns around INR 700 per day. 

        After using the batteries for some time, Ram founds that now his e-rickshaw is not running to the pre-defined kilometers. The battery is getting discharged in less duration. Ram calls XYZ and tells them about his issue. The XYZ company asks him to send the battery to them as they don’t have a service center in Chattisgarh. Ram sends the battery to the company where the service engineers check it and solve the problem and dispatch it back to Ram. But this entire process takes 7 days. Now for 7 days, Ram is not able to use his electric rickshaw. For seven days he is not able to earn and support his family financially. The total loss for Ram these days is around INR 4900.

        So when the next time something like this happens again, Ram simply switches to the local battery supplier, maybe going back to the lead-acid batteries.

        Now because of this, that company loses 1 customer directly. When Ram will tell all these to his friends and community, by the word of mouth a lot more possible future clients will be gone.

         

         

        Case 1: Fleet Owners

         

        In the second scenario, Ram owns a fleet of e-rickshaw and electric scooters for his logistics business or rental business. Let’s just say 30 e-rickshaw and 50 electric scooters. 

        Each e-rickshaw earns him INR 1000 and each electric scooter earns him 500 daily. So the daily income of Ram is around INR 55,000. Now let’s assume 5 of his e-rickshaws and 10 of his electric scooters are not working properly because of battery issues. 

        Ram calls the XYZ company, explaining the scenario and the company asks him to dispatch the batteries. Now here also the entire process takes 7 days. So the total loss for the Ram is around 77,000.

         

        In both cases, because the XYZ company didn’t have any service center, their client had to face economical loss. The company not only losses a client but also many future clients as well. But if the same company would have a network of the service center, that 7 days could have been reduced to say 3 days or 4 days.

         

        For battery manufacturers, it’s very important to have a network of battery service centers. Now if you will see this scenario, you can find 2 business opportunities. One is direct, that is starting a battery service center in collaboration with the battery manufacturers and the second is training. Lithium batteries are different from lead-acid batteries, they need different approaches while testing and servicing them. One can collaborate with the battery manufacturers to develop and launch a training model for anyone and everyone who wants to set up a battery service center.

        Ipower is collaborating with the brands/OEM’s and various dealers to set up lithium battery service centers in India to help the growth of EV industry of India.

        Thermal Management in Lithium Batteries

        Reducing reliance on fossil fuels has been a priority as India works to fulfill its commitment to achieving net-zero carbon emissions by the year 2070. India is actively promoting the use of electric vehicles (EVs) to achieve its goal of having 30% of private cars, 70% of commercial vehicles, and 80% of two- and three-wheelers powered by electricity by the year 2030. To promote the use of EVs, the government has introduced incentives for both manufacturers and end users. Although EV adoption is increasing, recent incidents of EV batteries catching fire have caused a great deal of fear and hesitation to buy EVs.

         

        What is a thermal management system in EV and why it is important?

        The effectiveness and longevity of batteries depend on proper thermal management. It’s crucial to keep your thermal management strategy in mind when choosing how to package and integrate a battery pack into a vehicle.

        Batteries are like Goldilocks; they don’t work well in extreme temperatures. To achieve the performance, dependability, and safety that OEMs are looking for, they must maintain the precisely right temperature. The battery pack’s capacity, cell balancing, capacity, charging speed, and service life will all be impacted by poor thermal management. A sound cooling plan will guarantee a uniform temperature distribution and get rid of any dangers that could arise from uncontrolled battery temperatures.

        EV-specific Thermal Management System (TMS) maintains the vehicle’s operation at an ideal temperature to preserve the vehicle’s safety and effectiveness.

        There are other factors as well, with safety being the most important. The batteries are higher energy density, high voltage Li-Ion batteries. Due to the increased density, even a slight temperature change could cause a fire hazard.

         

        Active thermal management: keeping cool or maintaining control?

        Active thermal management systems come in different varieties, and what sets those apart most is what they are used for. Some are intended to cool the battery, while others stabilize temperature extremes. There are mainly 3 types of active thermal management systems and they are as follows:

         

        • Air cooling 

        • Liquid cooling 

        • Thermoelectric coolers

         

        Air Cooling:

        Active air-cooling systems use convection to cool the battery pack by blowing air across it, typically from an AC unit or air drawn in from the outside.

        The simplicity and low cost of air-cooling systems are their main benefits. They are only meant to cool and stop overheating, though. They are unable to control a wide range of ambient temperatures as a result. Warm or even mild climates don’t have a problem with this, but colder climates can cause battery deterioration because EVs don’t like driving in the snow! Due to its low specific heat capacity, the air is not particularly effective at transferring heat away from the battery, even at moderate temperatures.

        There are concerns about the safety of using an air-cooling system for high-power applications as batteries grow in strength and charge capacity.

         

        Liquid Cooling:

        Liquid cooling, which involves pumping and circulating a liquid coolant, like glycol, around the battery in a closed loop, offers a more precise way to control thermal conditions and keeps them within a desirable range.

        To dissipate heat, heat is typically transferred to liquids through thermally conductive metal pipes that pull the heat away from the source. Since liquid-based cooling is so much more effective, it enables smaller, lighter, and more compact systems without requiring additional power or mass.

        This is very helpful because the automotive industry wants to use the lightest systems possible.

         

        Thermoelectric coolers:

        Another technique of thermal management that is causing a stir in the automotive sector involves sandwiching semiconductors between a heat sink and a heat source (in this case, a battery). When a voltage is applied, a temperature difference between the source and sink is created, which causes heat to be transferred through conduction. In situations where heat is needed, the direction of heat transfer could be changed by reversing the current. This enables precise control of temperatures by a straightforward change in voltage.

         

        Why passive thermal management system is required?

        The biggest drawback of all active BTMS is that they drain the battery of valuable power, which is regrettably their biggest drawback. Therefore, passive cooling or passive thermal management is required. The objective of passive thermal management is to allow the battery to control its temperature without the use of an external energy source.

        There are many passive cooling strategies in development, even though active management strategies are currently preferred for their effectiveness.

        For instance, heat pipes, which use a closed cycle of liquid evaporation and condensation to transfer heat from a battery, are very effective at doing so in smartphones. However, these solutions can only absorb heat from the battery, not draw it away from the source. Expect to see more of these passive techniques employed in the future due to the ongoing push to reduce parasitic power consumption in EVs.

        Past and the future of Lithium-ion Batteries

        In a world full of changes, there are a few universal constants that cannot be altered. One of them is “Energy can neither be created nor be destroyed, it can only be converted from one form to another”. This very statement by Julius Robert Mayer is the basis of energy storage solutions.

        Before talking about or predicting the future of lithium batteries, it’s very important to understand their past. We have to understand the significance of the fact that the entire concept of energy storage came from a frog experiment done by Luigi Galvani who was an Italian physicist.

        Although lithium batteries were not made commercially available until the late 20th century, Gilbert Newton Lewis was the first to experiment with them.

        These batteries were made possible by three significant developments:

        1. The LiCoO2 cathode was discovered by John Goodenough in 1980.
        2. Graphite anode was discovered in 1982 by RachidYazami.
        3. Asahi Chemicals created a prototype for a rechargeable lithium battery in 1985.

        After that, it was Sony Company that commercialized lithium-ion batteries.

        Now let’s head toward the future of lithium batteries via the roads of the present.

        Lithium batteries offer a chance to change the transportation industry, which currently emits a lot of carbon into the atmosphere. They also provide a remedy for the erratic energy generated by solar and wind power, making these environmentally friendly options more practical.

        New and cutting-edge chemistries and technologies have been developed and adopted over the past few years in the energy storage industry. One of the most recent adopters, lithium-ion batteries have gained popularity and respect for their chemistry, performance, and features. Lithium-ion batteries have a significantly higher energy density in joules per kilogram than earlier battery technologies like nickel-cadmium (NiCd) and nickel-metal hydride (NiMH).

        But the question is what the future of lithium-ion batteries is.

         

        Solid State Batteries:

        In terms of technology, solid-state batteries represent a paradigm shift. In all-solid-state batteries, the liquid electrolyte is swapped out for a solid substance that still permits lithium ions to move around inside of it.

        This idea is not new, but over the past ten years, extensive global research has led to the discovery of new families of solid electrolytes with extremely high ionic conductivity, comparable to the liquid electrolyte, enabling the removal of this particular technological hurdle.

        Pros of solid-state batteries

        • High thermal and impact safety because the liquid electrolyte is replaced by a solid
        • Reduced dendrite growth issues extend service lifetime
        • High-specific energy and low cost

        Cons of solid-state batteries

        • Cycle life is highly dependent on the specific anode-cathode mix (currently less than 1,000 cycles)
        • Not commercially viable currently; expected to reach the mass market in 3–5 years

         

        Lithium-sulphur Batteries:

        Lithium ions are stored in active materials that serve as stable host structures in li-ion batteries during charge and discharge. The host structures in lithium-sulphur (Li-S) batteries are absent. The lithium anode is consumed during discharging, and sulphur is converted into several different chemical compounds during charging.

        Pros of Lithium sulphur batteries

        • Higher specific energy and power discharge compared with conventional LiBs
        • High tolerance for extreme temperatures
        • Uses low-cost and easily disposable input material

        Cons of lithium-sulphur batteries

        • Low cycle life and longevity

         

        Lithium-Air batteries:

        The lithium-air batteries would function by producing lithium peroxide on the cathode during the discharge phase by fusing lithium already present in the anode with air oxygen.

        The area where air enters the battery is known as the cathode. Theoretically, lithium and oxygen can be combined to create electrochemical cells with the highest potential specific energy, comparable to the potential specific energy of gasoline.

        This is almost five times more powerful than a Li-ion battery. However, before becoming widely used, Li-air batteries’ useful power and life cycle require significant improvements. The market for electric vehicles is a significant market driver for batteries.

        Pros of Lithium-air batteries

        • Very high theoretical energy density
        • Uses abundant, low-cost materials for electrodes, offering a lower bill of materials

        Cons of Lithium-air batteries

        • Technology is still in the R&D stage, currently limited by low efficiency and poor cycle life

         

        Lithium-carbon Batteries:

        An emerging method of energy conversion and storage is the lithium-carbon dioxide battery. Even though these batteries are still in the early stages of development, researchers need to have a clear understanding of the major obstacles they must overcome to fulfill their potential as innovative energy storage systems.

        Researchers have focused their attention on carbon capture and storage because carbon dioxide is a significant factor in the cycles of the earth’s temperature. Lithium-CO2 batteries present an intriguing alternative for the storage of electricity generated by renewable energy sources as well as for the conversion of waste carbon dioxide into products with added value.

        Pros of Lithium-carbon batteries

        • Combines benefits of traditional LiBs with capacitors —good energy/power density and fast recharging
        • Promises low carbon footprint
        • Low-cost, relatively abundant materials
        • it does not need an external cooling system

        Cons of Lithium-carbon batteries

        Technology is in a very early stage, with a limited number of makers
