Stellantis and Factorial Energy to Develop Solid-State Batteries for EVs
Stellantis and Factorial Energy recently announced a joint development agreement to advance Factorial’s high-voltage traction solid-state battery technology. The agreement includes a strategic investment from Stellantis. Factorial has developed breakthrough solid-state technology that addresses key issues holding back wide-scale consumer adoption of electric vehicles: driving range and safety. Stellantis announced during its EV Day program in July 2021 its target of having the first competitive solid-state battery technology introduced by 2026. Factorial’s advances are based on FEST™ (Factorial Electrolyte System Technology), which leverages a proprietary solid electrolyte material that enables safe and reliable cell performance with high-voltage and high-capacity electrodes and has been scaled in 40Ah cells that perform at room temperature. FEST™ is safer than conventional lithium-ion technology, extends driving range, and is drop-in compatible for easy integration into existing lithium-ion battery manufacturing infrastructure.
