StoreDot, a leading developer of ultrafast charging battery cells, has announced a major breakthrough in battery performance, revealing that its cells can charge up to 80% of their full capacity in sub-freezing temperatures as low as 14F (-10C) when charged at standard speed. This development could significantly enhance the usability and range of electric vehicles (EVs) in cold climates.
Recent laboratory tests conducted by StoreDot have shown that its extreme fast charging (XFC) battery cells exhibit a consistent discharge rate and offer an adequate driving range even in sub-freezing conditions. At 14F (-10C), the cells delivered over 85% of their full range capacity, and at -4F (-20C), they provided over 70% of their full range capacity.
Dr. Doron Myersdorf, CEO of StoreDot, highlighted the significance of these findings, stating, “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.” He explained that while all lithium-ion batteries tend to lose capacity in extreme cold, StoreDot’s innovative design, which utilizes silicon-dominant anodes, minimizes this loss.
StoreDot’s strategic investors, including Daimler, Volvo, Polestar, Mercedes-Benz, and VinFast, have shown keen interest in the company’s progress. StoreDot is on track to release production-ready XFC cells capable of delivering 100 miles of range in just five minutes this year. The company aims to achieve the milestone of 100 miles charged in 4 minutes by 2026 and 100 miles charged in 3 minutes by 2028.
In addition to its advancements in battery technology, StoreDot also announced its plans to ship prismatic B-samples – prototypes with full usability and a high level of maturity – to original equipment manufacturers (OEMs) and expand its operations in the US in 2024.
