Stellantis Validates Solid-State Batteries for Electric Cars

This episode details a significant step forward in electric vehicle battery technology, announcing that Stellantis has successfully validated solid-state battery cells from Factorial through road testing. These Factorial Electrolyte System Technology (FEST) batteries have demonstrated operability across a wide temperature range, from -30°C to 45°C, addressing a common challenge for solid-state technology. Stellantis and Factorial are collaborating to optimize battery pack design, focusing on reducing weight and increasing efficiency. With impressive specs including 375 Wh/kg energy density and an 18-minute fast charge time (15%-80%), Stellantis aims to deploy a demonstration fleet featuring these batteries by 2026, signifying their commitment to this next generation of battery technology.
