The American Solid-State Battery That Just Leapfrogged Toyota's Decade-Long Roadmap carbuzz.com

Factorial Energy says its quasi-solid-state battery achieved 375 Wh/kg and charged a test Dodge Charger Daytona from 15% to 90% in 18 minutes; Stellantis is evaluating the cells, which have also logged more than 600 cycles in testing. Factorial says its manufacturing process is about 80% compatible with existing lithium-ion production, and it has an agreement with SK On targeting commercialization around 2029. The results are promising but do not establish that Factorial will beat Toyota to mass production.
