Factorial has developed breakthrough solid-state technology that addresses key issues holding back widescale consumer adoption of electric vehiclesn : driving range, and safety.

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 by 20 to 50 percent, and is drop-in compatible for easy integration into existing lithium-ion battery manufacturing infrastructure.
