The company’s extreme fast charging (XFC) cylindrical cells utilize a 4680 format – i.e., they have a diameter of 46 mm and length of 80 mm – which is increasingly favored by global car makers, and have been in development for over three years. Such cell design increases throughput and addresses safety and performance issues typically associated with the hard case structure of cylindrical cells.

This breakthrough, says the company, means that global automotive manufacturers will be able to use its XFC batteries, which deliver a 50% reduction in charging time at the same cost, in both pouch and cylindrical cell forms. Both formats are undergoing scale up process at EVE Energy, the company’s manufacturing partner in China, and will be ready for mass production in 2024.

“Achieving the goal of extreme fast charging a cylindrical cell in only 10 minutes has been on StoreDot’s technology roadmap from day one,” says Dr Doron Myersdorf, StoreDot CEO. “It’s highly significant that we can offer Electric Vehicle manufacturers the choice of cell formats, utilizing our XFC technology that will 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,” says Myersdorf. “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.”

This world-first application of silicon-dominant anode extreme fast charge cylindrical cells, says the company, signifies a number of considerable challenges that had to be resolved, when compared to pouch technologies. 4680 cylindrical cell format requires unique chemistry adaptation to offset greater internal pressures, gas release and avoidance of potential leakage.
