90% in 15 mins: US firm’s new EV battery achieves higher charge with silicon anode | The EV battery is close to achieving 1,000 cycles and has also passed the military nail penetration test.
By replacing the graphite electrode with silicon nanowires, Amprius achieves higher power density and faster charging for its lithium-ion batteries.
A new electric vehicle (EV) battery developed by California-based Amprius Technologies sports a silicon anode and can reach a 90 percent state-of-charge in 15 minutes. Amprius Technology, which has previously delivered quick-charging battery packs for the aviation and light vehicle markets, is now marking its foray into the EV sector with its A sample cells. Amprius began working on EV batteries after a $3 million award from USABC, a subsidiary of the United States Council for Automotive Research (USCAR), a technology company established by automakers Ford, General Motors, and Stellantis.
