  • Sodium-Ion Batteries Outlast Cars: CATL’s Cold Fix

    Sodium-Ion Batteries Outlast Cars: CATL’s Cold Fix

    Key Takeaway

    – CATL’s sodium-ion batteries achieved a 15,000-cycle lifespan (20 years), surpassing LFP batteries in high-frequency cycling.
    – Over $1.5 billion in R&D solved hard-carbon electrode issues, enabling a 300-mile range and extreme cold-weather resilience down to -25°C.
    – New “One Shell, Two Cells” platform allows swapping between lithium-ion and sodium-ion cells in the same chassis without modifying thermal systems.
    – Sodium-ion cell costs expected to match lithium by 2026 and become cheaper than LFP by 2027, with supplier Ronbay scaling cathode production.

    Big News from CATL’s Sodium-Ion Breakthrough

    CATL’s sodium-ion cells have now cleared a 15,000-cycle benchmark ahead of theyre mass production later this year, which translates to a 20-year operational lifespan. For comparison, that is a level of longetivity exceeding the one of the popular lithium iron phosphate (LFP) batteries when used in high-frequency cycling applications. This is a massive step forward for energy storage technology, showing that sodium can finally rival and even beat traditional chemistries in durabilty.

    Investments and Manufacturing Advances

    According to its industry briefing before China’s Ministry of Industry and Information Technology, CATL has invested close to $1.5 billion in R&D over more then a decade to crack the code of hard-carbon electrode manufacturing. It has resolved moisture control and cell gassing during production, resulting in a product that can outlast the vehicle it is instaled in, with energy density allowing a 300-mile range on the EPA cycle (600 km CLTC). This massive investment shows a long-term commitment to making sodium-ion viable for the masses.

    Cold Weather Performance is a Trump Card

    Then there’s cold-weather performance, which has historically been sodium-ion’s trump card over lithium, so CATL has built on the chemistry’s advantages. In northern regions like Xinjiang, where temperatures regularly fall below -25°C (77°F), conventional LFP batteries’ charging times can double and usable capacity can shrink by up to 40%. Sodiums electrochemical properties make it way less susceptible to this kind of winter degradation, making sodium-ion batteries a unique contender for application in passenger vehicles, logistics fleets, mining operations, and grid storage across freezing northern climates. This could be a game-changer for cold regions.

    New Platform Architecture

    To make Na-ion battery deployment frictionless ahead of mass production, CATL also detailed a new “One Shell, Two Cells” platform architecture. The design uses a standardized physical enclosure that can house either lithium-ion or sodium-ion cells within the exact same dimensional footprint, meaning operators can easily swap chemistries based on climate without touching the thermal management systems or vehicle chassis. This flexibility could simplify manufacturing and reduce costs for automakers.

    Supply Chain and Cost Parity Coming Soon

    CATL has achieved the 20-year battery lifespan with the help of its suppliers like Ronbay Technology, which makes the cathode mixes. Ronbay has confirmed that its sodium materials have independently verified the 15,000-cycle figure, and the supplier is now scaling capacity from 6,000 tons annually to a planned 28,000 tons by the end of 2026. Industry analysts expect that sodium-ion cell costs will reach parity with the current mass battery chemistry in 2026 and will become cheaper than the ubiquitous LFP batteries in 2027. This cost trajectory is extremely promising for widespread adoption.

    Key Takeaways

    1. China is introducing a standardization and classification system for solid-state batteries, focusing on solid-state electrolytes in its 5-year strategy, set to be official by July.

    2. Hybrid solid-liquid batteries, containing 95% solid electrolyte, are seen as a temporary solution before fully solid-state batteries, with companies like CATL continuing to use existing production lines.

    3. A new hybrid solid-liquid battery developed by FAW and Nankai University features manganese for the cathode, doubling the energy density to 500 Wh/kg compared to current LFP batteries.

    4. The innovative battery design incorporates in-situ-cured composite electrolyte technology, enhancing ionic conductivity, safety, and cost-effectiveness while extending battery lifespan.

    5. Prototype tests suggest that the hybrid battery could achieve over 1,000 km on a charge under favorable conditions, with plans for a future 200 kWh pack aiming for nearly 700 miles.

    As China focuses on solid-state electrolytes for the future of electric vehicle (EV) batteries in its new 5-year strategy, it is rolling out the first-ever standardization and classification system for solid-state batteries, which is set to be official by July.

    Classification of Batteries

    In this system, batteries are sorted based on the liquid content in their electrolyte. Those that contain 95% solid electrolyte have been termed hybrid solid-liquid batteries. Companies like CATL view this hybrid technology as a temporary solution leading up to fully solid-state batteries, which are known to be costly and typically have a shorter lifespan. The hybrids can still be manufactured using current lines designed for liquid electrolyte production.

    Breakthrough in Battery Technology

    Recent advancements in hybrid solid-liquid batteries are supporting CATL’s assertions. A new 142 kWh battery pack has been integrated into a FAW Group sedan, replacing an LFP battery that had about half the capacity of the new one.

    This innovative hybrid solid-liquid battery utilizes manganese for the cathode rather than the more costly nickel, achieving an energy density of 500 Wh/kg. This figure doubles the energy density of contemporary LFP batteries and aligns with the theoretical boundaries of first-generation all-solid-state batteries, which Toyota has claimed will be in its vehicles by 2028 amid much excitement.

    Collaborative Development

    The lithium-manganese battery with a solid-liquid electrolyte has been developed together by FAW, which is VW’s partner in China, and researchers from Nankai University. They have taken a different approach than existing semi-solid electrolyte batteries, such as the 150 kWh pack that NIO rents out for longer journeys, as it’s too pricey to sell with the car. NIO was a pioneer in this technology with its sedans, now capable of traveling over 650 miles on a charge of the hybrid liquid-solid battery.

    By replacing nickel with manganese, the researchers have successfully reduced the costs of the hybrid pack while maintaining energy density comparable to solid-state batteries. “The battery employs in-situ-cured composite electrolyte technology, which ensures high ionic conductivity, a broad electrochemical window, strong interfacial compatibility, flame resistance, and cost benefits,” the report reveals. The anode is also created in situ to enhance the battery’s longevity and safety, with the lithium-manganese cathode boasting an energy density of 300 mAh/g, surpassing even top LFP cells by a factor of two.

    Anticipated Performance

    Prototype range tests in FAW vehicles are projected to achieve over 1,000 km on a single charge. However, this figure is based on the more favorable local CLTC standard. With the average EV efficiency being about 30 kWh for every 100 miles, the hybrid battery is estimated to reach a 500-mile range according to EPA standards. The next version being prepared by the team is a 200 kWh pack that aims to deliver nearly 700 miles on a charge, all while maintaining a compact design.

    2. The battery can endure 1,400 charge-discharge cycles at extreme temperatures (60°C) and up to 3,000 cycles in milder conditions (20°C), making it the first million-mile EV battery with rapid charging capabilities.

    3. CATL’s range estimates for electric vehicles equipped with this battery are based on a 600 km (373-mile) average, which may be optimistic compared to EPA figures, but still allows for up to 750,000 miles of use before recycling.

    4. Innovations in battery design include self-repairing electrodes, consistent coating on the cathode to prevent cracks, and improved cooling systems, all contributing to enhanced longevity and safety.

    5. CATL is collaborating with NIO to supply these long-lasting batteries, aiming for a 15-year warranty and at least 85% capacity retention, which could significantly benefit the second-hand EV market.

    The largest battery manufacturer in the world has successfully combined the durability of electric vehicle (EV) batteries with rapid charging features. Following the introduction of the 4C Shenxing battery, which can go from 0-80% in just 15 minutes last year, a new version of its chemistry and production technique has increased the charging speed to 5C while ensuring a long lifespan.

    Impressive Charging Speed

    The latest 5C battery from CATL can be fully charged in only 12 minutes and still maintain at least 80% of its capacity throughout the electric vehicle’s lifespan. It can handle 1,400 complete charge-discharge cycles at 5C speeds in extreme heat of 60°C (120°F), or an astonishing 3,000 cycles in milder 20°C weather.

    This advancement means that CATL has developed the first million-mile EV battery capable of 5C charging, making those quick coffee-break charging advertisements a reality. The company claims that this battery can power an electric vehicle for over 1.8 million kilometers, which is around 1.12 million miles, before its capacity decreases to 80% of the original.

    Range Estimates and Comparisons

    It’s important to note that CATL’s calculations are based on a 600 km (373-mile) average EV range, which may seem a bit too optimistic, likely reflecting the local CLTC range testing cycle. This estimate is about a third more generous than the EPA’s figures in the US, as it includes more urban driving.

    However, even with this discrepancy, electric cars equipped with CATL’s new long-lasting battery will manage to cover up to 750,000 miles before the battery needs recycling, effectively outliving the vehicle based on the average annual mileage in the US.

    China has recently taken a big step by becoming the first nation to try to establish standards for solid-state batteries. Both new companies like WeLion and established players such as CATL are in competition to lead in the next generation of electric vehicle (EV) range and safety.

    Advancing Battery Technology

    The goal of the solid-state battery standard initiative is to hasten the process of bringing cells with solid or nearly solid electrolytes to the market. The new national classification differentiates between these types. Batteries that were previously labeled as semi-solid, which consist of 5% liquid and 95% solid electrolyte, are now referred to as hybrid solid-liquid batteries. These batteries are less expensive to produce compared to those with a 100% solid electrolyte, yet they are almost equally safe and provide significantly higher energy density than current ternary batteries that use volatile liquid electrolytes.

    Innovations from NIO and WeLion

    For example, NIO approached CATL to produce the solid-liquid battery it had developed. However, CATL, the largest EV battery manufacturer globally, initially dismissed the idea, viewing it as costly and not practical, which are two issues CATL typically avoids. Consequently, NIO sought assistance from the startup WeLion and successfully created a 150 kWh battery pack that allows its ET7 sedan to travel over 650 miles on just one charge.

    A Shift in Perspective

    Eventually, CATL revised its opinion and now sees solid-liquid batteries as a viable interim solution while working towards commercializing true solid-state batteries, which remain fairly costly to produce. In contrast, startups in China are focusing directly on developing and manufacturing hybrid or solid-state batteries, skipping the liquid electrolyte phase where they find it hard to compete against major companies like CATL or BYD.

    One such innovative company, Hylic, has started constructing the world’s first production line exclusively for hybrid batteries containing 95% solid electrolyte, also known as solid-liquid packs. Though these batteries don’t provide the same high energy density as solid-state batteries, Hylic’s cells, with only 5% liquid electrolyte, still achieve 360 Wh/kg, which is about 50% more than the average energy density of current EV batteries, and they can last for 1,000 charging cycles.

    Future of EV Battery Production

    The establishment of the first dedicated solid-liquid battery manufacturing plant could lead to electric vehicles capable of 500-600 miles of range at a reasonable cost, thanks to the benefits of large-scale production. Hylic has already initiated the first phase of construction and aims to deliver 10 GWh of solid-state battery capacity for various applications, including robots, drones, and electric vehicles.

Some analysts caution that the market may be reaching an overcapacity stage, which contributed to its status as a global leader in the EV and battery sectors. Hence, the news regarding CATL’s Moz robot deployment in mass production lines isn’t particularly surprising.
