Q&A

In April, Stellantis and Factorial Energy announced that the two companies validated automotive-sized solid-state battery cells with an energy density of 375Wh/kg. The companies called this “a major step toward commercial use.” Factorial's cells can charge from 15% to over 90% in 18 minutes at room temperature and have discharge rates up to 4C. Stellantis invested $75 million in Factorial in 2021. SAE Media recently spoke with Factorial CEO Siyu Huang about the partnership.
