Amprius Technologies has shipped its A-Sample EV cells to Ford, GM, and Stellantis' United States Advanced Battery Consortium (USABC).

Amprius’ new SiMaxx cells hit an impressive 360 Wh/kg in energy density – far beyond the USABC’s target of 275 Wh/kg. What does that mean for EV drivers? Simply put, longer range without a bulkier battery. Plus, these cells have a power density of 1200 W/kg, meaning more efficient energy delivery.
