Stellantis N.V. and Factorial Energy signed a joint development agreement to advance Factorial’s high-voltage traction solid-state battery technology. The agreement also includes a strategic investment from Stellantis. 

“Our investment in Factorial and other highly recognized battery partners boosts the speed and agility needed to provide cutting-edge technology for our electric vehicle portfolio,” said Stellantis CEO Carlos Tavares. “Initiatives like these will yield a faster time to market and more cost-effective transition to solid-state technology.”

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

“It is a great honor to partner with Stellantis, a leading global mobility player, which has some of the most iconic auto brands in the world,” said Siyu Huang, Co-founder, and CEO of Factorial Energy. “It is an incredible opportunity for us to advance the adoption of our clean, efficient, and safe solid-state battery technology to the mass market.”

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.
