Join the EV Revolution

Lithium batteries have revolutionized the way we use portable electronics, electric vehicles, and renewable energy storage systems. With various chemistries available, it’s crucial to understand the differences between them. In this blog, we’ll delve into the three prominent types of lithium batteries: Nickel Manganese Cobalt (NMC), Lithium Iron Phosphate (LFP), and Olivine Lithium Manganese Iron Phosphate (LMFP). Each type offers unique advantages and limitations that cater to specific applications.

• NMC Batteries: Power and Performance at a Cost

NMC batteries utilize a combination of nickel, manganese, and cobalt in their cathode, making them popular for electric vehicles due to their high energy density, power density, and cycle life. However, these batteries come with drawbacks. Cobalt, an essential component, is both scarce and expensive, often mined under unethical conditions. Additionally, NMC batteries have relatively low thermal stability, making them susceptible to thermal runaway if subjected to internal short circuits or abuse. Environmental concerns related to cobalt mining are also important to address.

• LFP Batteries: Safety and Sustainability on a Budget

LFP batteries employ lithium iron phosphate (LiFePO4) as their cathode material. The iron and phosphate used in LFP batteries are more abundant and cost-effective than the materials used in NMC batteries, mainly cobalt. These batteries are also less toxic, simplifying the recycling process at the end of their lifecycle. Moreover, LFP batteries demonstrate superior safety and thermal stability compared to NMC batteries. They can endure higher temperatures and larger power draws without entering thermal runaway. However, their lower energy and power density necessitate more space and weight to store the same amount of energy.

• LMFP Batteries: Striking a Balance

LMFP batteries combine the advantages of LFP and NMC batteries, offering a hybrid solution. By partially substituting manganese for iron in the cathode, LMFP batteries achieve higher voltage and capacity than LFP batteries while retaining the safety features of LFP and the energy density of NMC. As a result, they strike a balance between safety and high energy density, making them suitable for hybrid electric vehicles. Additionally, LMFP batteries benefit from using manganese, a more abundant and cost-effective material than cobalt, reducing the overall environmental impact and cost.

Challenges and Room for Improvement

Despite their unique strengths, each type of lithium battery faces certain challenges. LMFP batteries, for instance, have room for improvement in rate performance, particularly in terms of electronic conductivity and lithium ion diffusion coefficient. Enhancing these aspects would enable faster charging and discharging. Similarly, NMC batteries need to address issues related to cobalt sourcing and thermal stability to minimize environmental impact and enhance overall safety.

The world of lithium batteries offers a diverse range of options, each tailored to specific needs. NMC batteries cater to high-performance electric vehicles, LFP batteries to cost-effective and safe energy storage systems, and LMFP batteries to hybrid electric vehicles, striking a balance between safety and high energy density. As technology progresses, advancements in battery chemistry will continue, overcoming limitations and meeting the evolving demands of the market. With these developments, we can look forward to a more sustainable and efficient future, powered by lithium batteries.

What are Solid-State Batteries and why are they important?

If you are interested in battery technology and its applications, you might have heard about solid-state batteries. Solid-state batteries are a new type of battery that uses solid electrolytes instead of liquid or gel electrolytes. They are considered the next generation of batteries that can overcome the limitations and challenges of conventional batteries.

But what are the benefits and features of solid-state batteries? How do they work and what are their current prospects? How can you learn more about solid-state battery technology and stay updated with the latest developments and innovations?

In this blog post, we will try to explore these questions and share with you why you should learn about solid-state battery technology.

The Benefits and Features of Solid-State Batteries

Solid state batteries have many advantages over conventional batteries, such as:

Higher energy density: Solid-state batteries can store more energy per unit weight and volume than liquid or gel electrolytes. This means they can provide more power and range for devices and vehicles. For example, a solid-state battery can have an energy density of 500 Wh/kg, while a lithium-ion battery can only have an energy density of 250 Wh/kg.

Longer lifespan: Solid-state batteries can last longer and retain their capacity better than liquid or gel electrolytes. They can withstand more charge cycles without degrading or losing performance. For instance, a solid-state battery can last for 1000 cycles or more, while a lithium-ion battery can only last for 500 cycles or less.

Safer and more stable: Solid-state batteries are safer and more stable than liquid or gel electrolytes. They do not leak, catch fire, or explode if they are damaged or exposed to high temperatures, short circuits, overcharging, or physical abuse. They also do not suffer from thermal runaway, which is a phenomenon where a battery heats up uncontrollably and releases toxic gases.

Eco-friendly and sustainable: Solid-state batteries are more eco-friendly and sustainable than liquid or gel electrolytes. They do not contain toxic or scarce materials such as cobalt, nickel, or lithium that can harm the environment or cause social conflicts. They also do not generate waste or emissions that can pollute the air, water, or soil.

The Working Principle and Fabrication Methods of Solid State Batteries

Solid-state batteries work on the same principle as conventional batteries. They consist of three main components: a positive electrode (cathode), a negative electrode (anode), and an electrolyte. The electrolyte enables the flow of ions between the electrodes, creating an electric current.

However, unlike conventional batteries that use liquid or gel electrolytes, solid-state batteries use solid electrolytes. Solid electrolytes are materials that can conduct ions in their solid form. They can be classified into four types: polymer-based, ceramic-based, glass-based, and composite-based.

The fabrication methods of solid-state batteries vary depending on the type of solid electrolyte used. Some of the common methods are:

Thin-film deposition: This method involves depositing thin layers of electrodes and electrolytes on a substrate using techniques such as sputtering, evaporation, or chemical vapor deposition.

Powder processing: This method involves mixing powders of electrodes and electrolytes and compacting them into pellets using techniques such as cold pressing, hot pressing, or sintering.

Sol-gel processing: This method involves dissolving precursors of electrodes and electrolytes in a solvent and forming a gel-like network using techniques such as hydrolysis, condensation, or polymerization.

Electrospinning: This method involves spinning fibers of electrodes and electrolytes from a polymer solution using an electric field.

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?

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?

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?

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.

• 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

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.

Several technical considerations, including advancements in battery technology, charging infrastructure, and government incentives, have contributed to India’s shift towards EVs.

Role of Battery Technology:

The invention of lithium-ion batteries was a changing point for the electric vehicle sector. These batteries are lighter, smaller, and have a higher energy density than standard lead-acid batteries. Lithium-ion batteries also have a lower self-discharge rate, which means they can hold a charge for longer periods of time. The advancement of battery technology has enabled electric vehicles to reach longer ranges, increasing their practicality for everyday use.

Role of Charging Infrastructure:

The availability of charging infrastructure is a crucial issue in electric vehicle adoption. In India, the government has initiated a number of steps to build a strong charging infrastructure. The FAME (Faster Adoption and Manufacturing of Electric Vehicles) scheme, for example, offers financial incentives for the installation of charging stations across the country. Several private companies have also entered the market to provide charging infrastructure, making electric vehicle owners more accessible.

Role of Government Incentives:

The Indian government has created a number of incentives to encourage the use of electric vehicles. The FAME scheme, for example, offers subsidies for the purchase of electric vehicles. The GST (Goods and Services Tax) for electric vehicles has also been slashed from 12% to 5% by the government. Furthermore, the federal government has waived road tax and registration fees for electric vehicles in numerous states, making them more cheap to consumers.

Now lets see how the electric vehicle market is impacting other sectors.

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

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.

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.

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

• 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.

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.

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 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.

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

At Ipower, we manufacturer lithium-ion batteries for electric two-wheelers, three-wheelers, E-rickshaws, loaders and many more.

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.
