StoreDot, an Israeli lithium-ion battery company based in Herzliya and a pioneer of extreme-fast-charging (XFC) battery technology for electric vehicles (EVs), recently revealed its ‘silicon-dominant technology’ applied to XFC cylindrical cells that can be fully charged in just 10min. These cells use a 4680 format (46mm wide x 80mm long), which is increasingly favoured by global car makers and has been in development for over three years.

Pioneering work for these ‘breakthrough technologies’ was initiated at Warwick University in the UK with collaboration with StoreDot’s ‘strategic partner’ — BP. The work is covered with five patents in the area of cell design, and cylindrical cell sample production is now ramping up at EVE Energy, StoreDot’s manufacturing partner in China.

This technology means that global automotive manufacturers will be able to use StoreDot’s XFC batteries, which deliver a 50% reduction in charging time in both ‘pouch and cylindrical cell forms’. Both formats are undergoing scale-up processes at EVE Energy and will be ready for mass production in 2024.

Doron Myersdorf, StoreDot’s CEO, said: “Achieving the goal of ‘extreme fast charging’ a cylindrical cell in only 10min has been on StoreDot’s technology roadmap from day one. After three years of vigorous development and testing, along with leveraging multiple vectors of our world class researchers, I am hugely proud of the effective collaboration across our globe that enabled this important achievement.

“It is highly significant that we can offer manufacturers of electric vehicles the choice of cell formats, using our XFC technology to overcome the current barriers to EV ownership — range and charging anxiety. We are pleased that our silicon-dominant XFC battery cell chemistry is adaptable and can be applied to various packaging formats, to suit changing market needs.

“Both our cylinder and pouch cells are designed to be safe, reliable and stable, and are expected to be produced at scale by 2024. We are in advanced discussions with a number of global automotive manufacturers and we plan to supply them with various XFC cells, enabling a rapid transition to a zero-emissions electrified future.”
