StoreDot, a pioneer in extreme fast-charging (XFC) technology for electric vehicles (EVs) and a portfolio company of Veligera, has announced a major breakthrough in the development of silicon-based cylindrical 4695 battery cells. With this advancement, StoreDot’s portfolio now encompasses all major EV battery formats: pouch, prismatic, and cylindrical cells.
StoreDot’s universal XFC technology has successfully addressed the challenges associated with silicon-based batteries, including swelling. The new 46xx cylindrical cell format, already adopted by leading automakers, is set to revolutionize the industry, delivering unprecedented charging speeds and energy density.
StoreDot anticipates that the cylindrical cells will match the XFC performance achieved in other formats, recharging from 10% to 80% state of charge (SOC) in just 10 minutes. Early integration tests have demonstrated promising results, with a projected lifespan of 1,000 full charge cycles. Additionally, these cells boast an energy density exceeding 800 Wh/L, a significant leap forward for the industry.
StoreDot’s silicon-dominant XFC technology has garnered global interest, with top-tier automakers actively testing and optimizing the technology for their next-generation EV models.
Beyond the EV market, StoreDot sees extensive potential for its 46xx cylindrical cells across various applications. Their compact and durable design, superior energy density, and extended lifespan make them ideal for a wide range of use cases.
The cylindrical cells are currently undergoing scaling processes in collaboration with StoreDot’s manufacturing partner in South Korea, with mass production targeted for late 2025.
