Stellantis and Massachusetts-based solid-state battery developer Factorial Energy have signed a joint development agreement to advance Factorial’s high-voltage solid-state battery technology. The agreement also includes a strategic investment from Stellantis. 

Factorial says its solid-state batteries offer 20 to 50 percent more range and increased safety, at the same cost as conventional lithium-ion batteries. The company’s proprietary FEST (Factorial Electrolyte System Technology) leverages a solid electrolyte material that has been successfully scaled in 40 Ah cells, works at room temperature, and can be produced using most existing Li-ion battery manufacturing equipment. The company is integrating its technology with several auto manufacturers.

“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.”

“It is a great honor to partner with Stellantis,” 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.”
