Silicon-dominant extreme fast charging (XFC) technology firm StoreDot has confirmed its battery cells offer consistent and reliable winter performance.
Recent laboratory tests show StoreDot’s silicon battery cells reach 80% capacity when charged at -10°C with standard charging speed.
StoreDot’s battery cells have been tested and have shown a consistent discharge rate and an adequate driving range, even in sub-freezing conditions, it claimed.
At a temperature of 14°F (-10°C), the cells delivered over 85% of their full range capacity. Even in the extreme cold of -4°F (-20°C), the cells still provided over 70% of their full range capacity, the firm announced.
StoreDot has recently announced its anticipated milestones for 2024, which includes the demonstration of the world’s first EV pack equipped with XFC technology, shipping prismatic B-samples to OEMs, and expanding operations in the US on the path toward commercialisation.
The company also said it was on track with production-readiness of XFC cells that can deliver 100 miles charged in 5 minutes this year. The company aims to achieve 100 miles charged in 4 minutes in 2026, and 100 miles charged in 3 minutes by 2028.
Dr Doron Myersdorf, CEO of StoreDot, said: “Our latest tests have demonstrated that our batteries can outperform traditional cold weather range and charging limitations that often hamper electric vehicles in colder climates.
“Although all lithium-ion batteries tend to lose capacity in extreme cold, our innovative design that uses silicon-dominant anodes minimizes this loss.
“Our batteries deliver optimal driving range even in most extreme, subzero conditions. With our revolutionary technology drivers can now conquer winter’s toughest challenges, ensuring a smooth driving experience in any climate or conditions and eliminating winter range anxiety.”
