  • CATL to Start Solid-State Battery Production in 2027 Amid Scale Concerns

    CATL to Start Solid-State Battery Production in 2027 Amid Scale Concerns

    Key Takeaways

    1. CATL will not start large-scale production of solid-state batteries for EVs capable of over 1,200 miles on a single charge by 2027, contrary to some rumors.
    2. The company plans pilot production of solid-state battery cells in 2027 but on a limited scale, with claims of energy density achieving 1,252 miles overstated.
    3. Current advancements in solid-state battery technology are still in the research phase, with a peak energy density of 500 Wh/kg, which is double that of current liquid electrolyte batteries.
    4. CATL has been investing in solid-state battery technology for over a decade and aims for small-scale production by 2027, with a projected manufacturing maturity level of 7 or 8.
    5. Solid-state batteries are costly to produce and currently more suitable for specialized applications like drones and robots rather than mass-market electric vehicles, where LFP battery technology remains dominant.

    CATL has clarified that it will not begin large-scale production of a solid-state battery that can power an electric vehicle (EV) for over 1,200 miles on a single charge by 2027, as some rumors suggested.

    Pilot Production Plans

    The leading battery manufacturer will indeed start pilot production of solid-state battery cells at that time, building on its existing trial production line, although it will be on a limited scale. Furthermore, the claim that its solid-state battery will feature an energy density capable of achieving 2,000 kilometers (1,252 miles) on one charge appears to have been overstated.

    Current Developments in Technology

    While there are advancements in solid-state battery technology that could enable such an EV, these innovations are still in the research phase and not yet ready for market. CATL has already stated that its solid-state battery technology boasts a peak energy density of 500 Wh/kg. This remains the theoretical maximum for mass production-ready solid-state batteries, which is double the capacity of current EV batteries utilizing liquid electrolytes. For example, a solid-state battery with this density recently powered a Mercedes EQS prototype for an impressive 749 miles on a single charge, significantly exceeding the average EV range.

    CATL emphasized that the “commercialization of solid-state batteries, along with the development of the supply chain, is still quite a ways off.” This has been its stance since 2022 when NIO requested the manufacture of its cells using semi-solid electrolytes. At that time, CATL projected that true mass production of solid-state batteries would not commence until around 2030.

    Ongoing Research and Investment

    However, this does not imply that CATL is not advancing its solid-state battery technology. The company has been researching this area for over ten years, involving 1,000 engineers in the development process and operating a pilot production line. “CATL is committed to investing in solid-state battery technology, maintaining its position as a leader in the industry, and expects to achieve small-scale production by 2027,” the company stated, in an effort to manage expectations. Last year, the CEO of CATL rated the industry’s readiness for mass production of solid-state batteries at a 4 on a 9-point scale. He mentioned that by 2027, CATL aims to reach a manufacturing maturity level of 7 or 8, which would enable the production of initial batches, though it remains unclear which EV manufacturer will be the first to receive them.

    Cost and Market Suitability

    While solid-state batteries offer improved energy efficiency and safety, they are also quite expensive to produce. NIO has warned that its 150 kWh pack with a semi-solid electrolyte costs as much as a typical EV, and it is only available for rent during extended summer trips. As production scales up, the costs are expected to gradually become more favorable, but for now, CATL considers solid-state batteries to be more appropriate for applications in drones and robots, where energy density is more critical, rather than for mass-market electric vehicles. In that segment, the widely used LFP battery technology continues to dominate, powering everything from new compact Anker Prime power banks to large energy storage systems.

This is more than double the density of widely used LFP batteries that power everything from mainstream electric vehicles to the well-known Anker Solix power station, which is currently available at a significant discount of over 50% on the Amazon Prime Big Deal list.

    Advantages of Solid-State Batteries

    In addition to potentially doubling the range on a single charge within the same size, solid-state batteries are also considered safer due to their reduced number of reactive components when compared to those utilizing flammable liquid electrolytes. However, true solid-state batteries come at a high cost, as the process requires fusing the electrolyte with the electrode at elevated pressures and temperatures, leading to weaker connections between the layers and a decrease in lithium-ion transport efficiency.

    Breakthrough Innovations

    This limitation hampers solid-state batteries from achieving their full capabilities. To address this issue, researchers from the Chinese Academy of Sciences have created an innovative solid-state battery electrolyte solution.

    They removed the “solid” aspect from the solid-state electrolyte by developing a flexible polymer incorporating ethoxy groups and short sulfur chains, which are intended to enhance ion conductivity and bond with the cathode on a molecular level.

    The new polymer electrolyte within a composite cathode not only improved the energy density of the solid-state cell by a remarkable 86% due to reduced transfer resistance, but it is also capable of bending. Indeed, this flexible solid-state battery system can endure 20,000 bending cycles, further improving its impact resistance and safety compared to traditional sulfide solid-state batteries that companies like Samsung and Toyota are set to launch in 2027.

    Future Implications

    Such a significant increase in energy density could allow the Mercedes EQB prototype, equipped with a genuine solid-state battery currently undergoing range testing, to potentially travel over 1,300 miles on just one charge. Furthermore, a solid-state battery featuring a flexible polymer electrolyte would enhance the longevity and safety of electric vehicles, provided it can be manufactured at a scale that reduces production costs to a competitive level.

    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.
