Lithium-ion battery developer StoreDot’s silicon-dominant cells have reached more than 1200 cycles with cells that are taken to 80% of charge in 15 minutes and then discharged for one hour.
The Israel-based firm said the results were achieved with a high energy density of 300Wh/kg and 680 Wh/l in “real-world” conditions at room temperature and with no “additional pressure” applied.
The company is advancing to B-samples, using larger form factors, to ship to global automotive manufacturers for testing in future electric vehicles later this year.
Yaron Fein, StoreDot vice president R&D, said: “1,200 consecutive cycles of extreme fast charging is a critical milestone that would have been unimaginable just two years ago.
“It reaffirms our roadmap of delivering ‘100in5’ cells for global automotive manufacturers within two years.”
StoreDot’s development program extends to deliver 100 miles of range after just two minutes of charge within a decade.
StoreDot’s fast charging cells will be available in both pouch and the 4680 form factor when commercialised.
