  • Tesla to Allow 90% Charging for Future U.S. Owners with Nickel Battery

    Tesla to Allow 90% Charging for Future U.S. Owners with Nickel Battery

    Key Takeaways

    1. Tesla is introducing advanced nickel cells that allow charging up to 90% without harming battery life, improving vehicle range by 10%.
    2. To extend the lifespan of nickel-based batteries, Tesla advises against keeping them charged to max or below 20% for long periods.
    3. LFP batteries, used in other Tesla models, can be charged to 100% regularly without harming lifespan, unlike nickel batteries.
    4. Tesla has stopped offering LFP battery options in the US due to sourcing issues and federal tax credit limitations.
    5. Tesla plans to build its own factory for LFP batteries, but currently, all US cars are equipped with nickel cells.

    Tesla is gearing up to equip its cars with advanced nickel cells that can be charged up to 90% without harming the battery pack’s life, as mentioned by chief engineer Lars Moravy.

    Enhanced Charging Capabilities

    Currently, almost all of Tesla’s vehicles available in the US are fitted with nickel batteries. This new technology upgrade will enable future Tesla owners to safely extend the range of their vehicles by an extra 10%, even during regular use.

    Battery Lifespan Advice

    Tesla usually suggests in the owner’s manual that to extend the lifespan of nickel-based batteries, drivers should avoid keeping the battery charged either to the max or below 20% for long periods. While nickel battery chemistry offers higher energy density and better performance, it can be sensitive regarding the charge state and may degrade more quickly if maintained at 100% for too long.

    To mitigate this, Tesla recommends charging to a full 100% only for long trips, which will quickly reduce the battery’s charge after being filled. They also suggest setting the charge limit to 100% the night before a journey and using the Departure Time feature to ensure the battery reaches full capacity just before leaving.

    LFP Battery Differences

    These guidelines don’t apply to Tesla cars that use LFP batteries, typically found in energy storage systems or popular charging stations like the Anker Solix C1000. LFP cells, while having lower energy density, are built with a less volatile chemistry, allowing them to be charged to full capacity regularly with minimal impact on the battery’s lifespan. In fact, Tesla advises charging vehicles with LFP batteries to 100% at least once a week to calibrate the capacity counter, as lower charge levels can disrupt its accuracy.

    Unfortunately, Tesla has stopped providing LFP battery options in the US market, including the entry-level RWD models. Most of these batteries are sourced from China, which means vehicles using them can’t qualify for federal tax credits or become costly to produce due to tariffs on imports of Chinese LFP batteries.

    Future Battery Plans

    Tesla is working on its own factory for LFP batteries, but for now, all cars sold in the US are equipped with nickel cells. Thus, the opportunity to regularly charge to 90% will likely be more valued in the US compared to other regions where Tesla operates.

  • First US Deployment of Sodium-Ion Battery for Affordable Energy Storage

    First US Deployment of Sodium-Ion Battery for Affordable Energy Storage

    Key Takeaways

    1. The US has launched its first grid-level energy storage system using sodium-ion batteries, developed by startup Peak Energy, which is safer and more affordable than traditional lithium phosphate batteries.

    2. Sodium-ion batteries offer enhanced safety due to fewer flammable materials and are cheaper to manufacture, making them a cost-effective alternative for energy storage.

    3. Peak Energy’s sodium-ion system features passive cooling technology, reducing operational risks by 90% compared to traditional systems, and is the largest sodium-ion battery system utilizing phosphate pyrophosphate cathode chemistry.

    4. The NFPP cells in the new energy storage system have a lifespan that allows for 20% lower operational costs and degrade at a third of the rate of lithium phosphate systems.

    5. The deployment of this technology supports a growing trend for American-made products in the battery industry, which has been largely dominated by China.

    After China, the US has now welcomed its first grid-level energy storage system featuring sodium-ion batteries. These innovative batteries do not need active cooling and are priced at one-third less compared to traditional battery energy storage systems (BESS) that utilize lithium phosphate batteries.

    First Deployment in the US

    The inaugural sodium-ion BESS has been launched by the startup Peak Energy, about two years after they expressed their plans to create one. In China, grid-level energy storage systems with sodium-ion batteries are already in use, crafted by major companies like BYD, which is the second-largest cell manufacturer globally. However, the American version stands out as it employs passive cooling, making it both more affordable and safer.

    Safety and Cost-Effectiveness

    In contrast to conventional lithium iron phosphate (LFP) batteries, such as those found in the popular Anker Solix C1000 mobile station and large-scale electricity storage projects, sodium-ion batteries contain fewer flammable materials. This quality inherently makes them safer than lithium batteries. Furthermore, the materials used in sodium-ion batteries are inexpensive and plentiful, resulting in lower manufacturing costs.

    Peak Energy has emerged as a leading battery startup in the US, and successfully delivering an actual commercial product, rather than just a prototype, is an impressive milestone. The containers that have been deployed on a megawatt-hour scale represent the largest sodium-ion battery system in the world that utilizes phosphate pyrophosphate (NFPP) cathode chemistry.

    Enhanced Lifespan and Efficiency

    Not only do the NFPP cells offer energy density that is similar to LFP cells, but they also boast superior thermal safety. Additionally, Peak Energy’s first NFPP energy storage system in the US is 20% cheaper to operate throughout its lifespan. The less reactive nature of the NFPP cells allows them to degrade a third slower than lithium phosphate systems over the same duration, which could enable utilities to use the Peak Energy BESS for extended periods.

    What makes this system distinct is its pioneering passive cooling feature, which significantly reduces around 90% of the risks associated with grid-level energy storage setups. Most incidents arise from the moving parts and electrical components, not the thermal runaway situations within the cells themselves.

    Domestic Manufacturing Trend

    While safety and costs are crucial factors, the deployment of Peak Energy’s sodium-ion BESS also aligns with the growing domestic preference for American-made products. This trend has largely overlooked the US battery industry until now, which has been predominantly influenced by China on a global scale.

  • Tesla’s New LFP Battery Factory Could Lower Model Y and 3 Prices

    Tesla’s New LFP Battery Factory Could Lower Model Y and 3 Prices

    Key Takeaways

    1. Tesla previously relied on Chinese-made LFP batteries, which disqualified its basic Model 3 from federal tax credits.
    2. The company is building its own LFP battery factory in Nevada to produce affordable batteries for electric vehicles and energy storage solutions.
    3. Tesla’s new LFP factory aims to enable the return of more affordable models like the standard-range Model 3 and a cheaper RWD Model Y.
    4. Future challenges include potential elimination of federal tax credits and reliance on older production equipment compared to competitors’ advanced technology.
    5. American-made LFP batteries may not be as cost-effective as Chinese counterparts but will help reduce reliance on China and support more affordable vehicle options in the U.S. market.

    Before President Biden’s administration introduced federal tax credit subsidies for batteries and electric vehicles made in the US, Tesla primarily sold its least expensive standard-range models equipped with batteries from China.

    These CATL iron phosphate (LFP) cells, produced by the world’s largest battery manufacturer, caused vehicles like the basic Model 3 to miss out on federal tax credits since they were merely assembled in Fremont, while the actual components came from China.

    Tesla’s New Battery Factory

    In response, Tesla opted to construct its own LFP battery factory, recognizing that the affordable LFP technology is essential not just for mainstream electric vehicles but also serves as a foundation for energy storage solutions. This includes popular mobile power stations in the Anker Solix series and Tesla’s large Megapacks.

    Although Biden’s clean energy tax credits might be at risk due to the proposed Big Beautiful Bill federal budget pending a vote, Tesla is proceeding with its LFP battery factory project.

    Progress in Production

    The company revealed that the installation of the LFP production line in Nevada is “nearing completion,” suggesting that its initial products featuring made-in-the-US LFP batteries are imminent. Currently, Tesla delivers its least expensive RWD Model Y with 2170 cells, which do not utilize the affordable iron phosphate chemistry. Therefore, the LFP factory could enable a more affordable RWD Model Y and bring back the standard-range Model 3 as the least expensive Tesla vehicle.

    However, it’s uncertain how competitive Tesla’s new LFP battery will be. The company aimed to navigate around the made-in-US tax credit requirements similar to Ford’s strategy for its LFP cell facility. Instead of purchasing Chinese cells directly, Tesla sought production line equipment and expertise from CATL.

    Future Challenges

    While this strategy technically qualifies Tesla’s LFP batteries for the $45/kWh federal subsidy on the completed pack, the tax credit may be eliminated as soon as this year, possibly leaving Tesla with outdated equipment. CATL’s state-of-the-art LFP cells that power direct competitors to the Model Y, like the Xiaomi YU7, boast some of the highest energy densities in their category and can charge in just 12 minutes. By the time the Nevada factory begins mass production of made-in-US cells, the equipment supplied to Tesla will be two years old.

    Furthermore, Tesla is unlikely to implement the more affordable but intricate dry electrode manufacturing process from its 4680 Cybertruck battery for the LFP ones, since CATL employs a different design and production technique for their iron phosphate cells.

    Nonetheless, while the American-made Tesla LFP batteries may not be as cost-effective as those sourced directly from CATL, they will reduce Tesla’s reliance on China for Megapacks and may facilitate the introduction of more affordable Model Y and Model 3 options in the US market as well.

    New Innovations in Battery Technology

    Following its introduction of the first commercial sodium-ion battery pack for electric vehicles, which boasts a range of over 300 miles per single charge, CATL has now rolled out a pioneering 9 MWh energy storage system (ESS).

    The latest Tener Stack solution utilizes CATL’s recent advancements in battery chemistry and packaging, which significantly boosts energy density and capacity, fitting into a standard 20-foot energy storage container.

    Previous Milestones

    Approximately one year ago, CATL introduced the world’s first mass-produced energy storage solution with a capacity of 6.25 MWh, named Tener. At that time, it featured a 20% reduction in size and a 30% increase in energy density compared to earlier 20-foot energy storage solutions.

    With the help of CATL’s solid electrolyte interphase and other cutting-edge technologies, the highly reactive lithium in the LFP batteries is safeguarded against oxidation, which prevents thermal runaway and slows down capacity loss. As a result, CATL was able to offer a 5-year zero degradation and a 20-year overall warranty with the Tener system, a first of its kind.

    Introducing Tener Stack

    The new energy storage solution, known as Tener Stack, retains the same zero capacity degradation warranty as its 6.25 MWh predecessor.

    CATL proudly declares, “This is the world’s first mass-produced 9 MWh ultra-large capacity energy storage system solution,” asserting that the company has made significant advancements in system capacity, safety, deployment flexibility, and transportation efficiency, heralding a new era for large-scale storage technology with the Tener Stack.

    With a 9 MWh energy storage capacity, the 20-foot container can supply power to an average single-family home for up to six years, with CATL guaranteeing the cells will not experience capacity degradation for the first five years. Additionally, it has the potential to charge up to 150 electric vehicles, based on the current average battery size. CATL highlighted this capability while showcasing the solution at the Electrical Energy Storage (EES) 2025 expo in Munich, particularly for the typical German household.

    Enhanced Design and Efficiency

    The Tener Stack system employs LFP battery cells, similar to those found in well-known mobile power stations like Anker’s Solix C1000, which is currently on sale for 50% off at Amazon. In this case, CATL has improved space utilization by 45%, resulting in a 50% increase in energy density compared to traditional 6 MWh energy storage solutions.

    This enhancement allows utilities to develop a standard grid-level 800 MWh energy storage park using fewer containers, thus requiring 40% less land for deployment. Moreover, CATL has tackled the logistical difficulties of transporting these heavy LFP battery cells.

    The new Tener system has been designed as two identical half-height units, each weighing just under 36 tons, which is the typical legal limit for heavy shipment ground transport. When they arrive, the units can be combined into a 20-foot container, which is reflected in the “2-in-1” design and the name Tener Stack.

    Cost-Effective Shipping and Safety Features

    CATL has streamlined the loading process by utilizing standard container spreaders and liners, which has reduced shipping costs by 35%. The structural 2-in-1 design also permits the Tener Stack system to be sent to hard-to-reach areas where weight limits for bridges and tunnel heights might be problematic.

    As for safety, CATL highlights the leading thermal management of its LFP batteries, alongside new gas sensors that allow for rapid response to runaway events. The upgraded insulation further enhances fire resistance. The system meets the IEEE693 standard, capable of withstanding a magnitude 9 earthquake or a Category 5 storm.

    To save space and minimize thermal radiation, the thermal management system is positioned at the top of the container. The resultant noise level is maintained at 65 dB from three feet away, making CATL’s Tener Stack ESS suitable for urban environments as well.

  • CATL Sodium-Ion Battery Approaches LFP Energy Density at Lower Cost

    CATL Sodium-Ion Battery Approaches LFP Energy Density at Lower Cost

    Key Takeaways

    1. Cost Efficiency: CATL’s sodium-ion batteries are expected to be cheaper to produce than current iron phosphate (LFP) cells when mass production begins.

    2. Energy Density Advancements: Sodium-ion cells are approaching energy density levels comparable to LFP batteries, overcoming a key barrier to their broader adoption.

    3. Positive Market Outlook: The launch of the first sodium-ion power bank indicates a favorable trend for increased adoption of this technology and competitive pricing.

    4. Cautious Commercialization: CATL takes a conservative approach to commercialization, focusing on viable mass production rather than high-priced niche products.

    5. Solid-State Battery Timeline: CATL has experience in solid-state batteries but predicts widespread use won’t occur until after 2027, reflecting their cautious strategy.

    At a recent quarterly meeting with investors, Contemporary Amperex Technology Co. Ltd. (CATL), recognized as the largest battery manufacturer in the world, provided insight into its plans for sodium-ion cell production.

    Cost Efficiency in Production

    When CATL’s second generation of sodium-ion batteries is fully ramped up for mass production, the expenses involved will be significantly reduced compared to the current most economical battery type, which is the iron phosphate (LFP) cells.

    Advancements in Energy Density

    An even more crucial point in CATL’s sodium-ion battery progress update is the assertion that its sodium-ion cells are nearing the energy density levels of the common LFP battery technology, which is dominant in both 200W power banks and mainstream electric vehicles. This was previously the central barrier to broader sodium-ion battery adoption, as these batteries have mostly been utilized for proof-of-concept electric vehicles or energy storage projects that don’t demand high energy densities.

    Positive Outlook for Mass Adoption

    The recent introduction of the first sodium-ion power bank suggests a positive outlook for the widespread use of this technology. If CATL, the world’s leading battery producer, is making advancements in its development, then competitive pricing should follow soon after.

    CATL’s sodium-ion battery update is quite a notable advancement, not just because it claims that producing cells without lithium will be cheaper than LFP technology, but also because it believes that mass production is unavoidable. They stated, “once large-scale adoption is achieved, sodium-ion batteries will have a certain cost advantage over LFP batteries.”

    CATL’s Conservative Approach

    CATL has reached the top of the battery industry by being cautious with its commercialization predictions of new technologies. Unlike smaller startups striving for breakthroughs in solid-state or sodium-ion batteries that lead to high-priced and niche products, CATL prioritizes the mass production viability of new battery chemistries or packaging technologies.

    When NIO requested a collaboration on its battery utilizing 95% solid electrolyte, CATL dismissed the idea, citing the resources needed to fulfill existing orders for its numerous clients. NIO subsequently developed a 150 kWh semi-solid-state battery for its ET7 sedan with a startup, but CATL was correct in predicting that the battery became too costly, and now NIO is leasing it for extended summer journeys.

    Cautious Optimism for Solid-State Batteries

    This is not to imply that CATL lacks experience in solid-state battery development; they have a decade of work in this area. However, the company warns that widespread use won’t occur until after 2027. This is sooner than their earlier 2030 estimate, but CATL tends to prioritize caution, and a similar strategy appears to be in effect with their sodium-ion battery technology.

    Despite CATL’s sodium-ion battery energy density apparently nearing that of LFP batteries, the company seems to be taking a deliberate approach to refine the chemistry while considering what will be practical for low-cost mass production.

  • Tesla Superchargers Boost Cold Charging Speed for Model Y LFP Batteries

    Tesla Superchargers Boost Cold Charging Speed for Model Y LFP Batteries

    Tesla is set to launch a battery heating feature at its V3 and V4 Supercharger stations. This enhancement will enable standard range Model 3 and Model Y RWD versions equipped with LFP batteries to charge up to four times quicker during winter months.

    Performance in Cold Weather

    Typically, LFP cells, like those found in portable power stations, do not perform as well in low temperatures. This might be a reason why Tesla has prioritized the Supercharger battery heating option specifically for the standard range Model Y and Model 3.

    Innovative Heating Method

    The new heating service differs from the usual preconditioning process that Tesla vehicles undergo when heading to a Supercharger. Instead of slowly warming up the battery pack, the Supercharger transmits ripple AC current straight through the individual LFP battery cells, effectively heating them during cold weather conditions.

    “This is made possible by Tesla’s vertical integration and some of our brilliant engineers,” says Max de Zegher from Tesla. He notes that this new feature might remain exclusive to vehicles that utilize CATL LFP batteries.

    Speeding Up Charging Times

    The Supercharger battery heating option can allow a standard range Model Y to get back on the road up to four times faster than previously, addressing the main issue faced by LFP batteries. Elon Musk has previously discussed the slower charging speeds of Teslas with LFP batteries in extreme conditions:

    In cold weather, LFP batteries charge at a slower rate compared to NCA batteries, and their range diminishes more than that of NCA batteries as well. It’s important to remember that both types of batteries perform poorly in cold weather, but LFP batteries are more affected. While on a road trip to a Supercharger, the vehicle will prewarm its batteries, which can help alleviate some of the slower charging issues. However, this means you may spend an additional six or seven minutes at the Supercharger during winter with LFP batteries. This could be a concern if you intend to rely on your vehicle for frequent cold weather supercharging, though it won’t affect you if you charge your car at home overnight.

    Tesla’s LFP battery supplier, CATL, now has new LFP cells that do not experience slow charging in cold conditions. However, these specific cells are not used in the standard range Model 3 or Model Y. In the US, Tesla is primarily selling only long-range options, as its vehicles with Chinese LFP cells do not qualify for federal tax incentives.

Rivals LG Energy Solution and Samsung SDI have also announced their plans to target mass production of LFP products in 2026.

    Focus on Energy Density and Efficiency

    SK On, a battery unit of South Korean energy group SK Innovation, is considering the possibility of manufacturing LFP batteries in Europe or China. Choi acknowledged the challenge of competing with Chinese LFPs on cost but emphasized that the company’s focus is on energy density, charging time, and efficiency rather than price alone.

    Concentration on European Market for LFP Batteries

    Although SK On has production facilities in the United States, South Korea, Hungary, and China, the company is not currently in talks with its U.S. automaker customers regarding LFP supply. Choi explained that the high cost of building LFP factories in the United States makes it less feasible. Instead, the company is primarily concentrating on the European market.

    Chinese Dominance in LFP Production

    Chinese battery manufacturers, such as CATL and BYD, currently dominate global LFP production. They benefit from strong demand in their home market. LFP batteries from Chinese manufacturers are approximately 20% cheaper than nickel-based alternatives, making them an economical option for EVs, although they may have slightly reduced range compared to nickel-based alternatives. SK On is also working on the development of prismatic and cylindrical-type EV batteries, with notable progress in the latter, which is used by Tesla and other automakers.
