Thanks to recent laboratory tests, StoreDot confirmed that its battery cells can recharge even in freezing weather, while still maintaining a consistent driving range. These recent tests show StoreDot’s silicon battery cells reach 80% capacity when charged at -10°C (14°F) with standard charging speed. StoreDot said its battery cells have been tested and have shown a consistent discharge rate and an adequate driving range, even in sub-freezing conditions. At a temperature of 14°F, the cells delivered over 85% of their full range capacity. Even in the extreme cold of -4°F, the cells still provided over 70% of their full range capacity, the company 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,” Dr. Doron Myersdorf, CEO of StoreDot, said. “Although all lithium-ion batteries tend to lose capacity in extreme cold, our design that uses silicon-dominant anodes minimizes this loss. Our batteries deliver optimal driving range even in the most extreme, subzero conditions.”

StoreDot also recently announced milestones for 2024. These include the demonstration of an EV pack equipped with its XFC (extreme fast charging) technology, shipping prismatic B-samples to OEMs and expanding operations in the US on the path toward commercialization.

StoreDot said it is on track with the production-readiness of XFC cells that can deliver 100 miles charged in five minutes this year. The company aims to achieve 100 miles charged in four minutes in 2026 and 100 miles charged in three minutes by 2028.
