Dutch automaker Stellantis has signed a joint development agreement with solid-state battery developer Factorial Energy 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 recognised 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 solid-state technology that aims to address issues holding back wide-scale consumer adoption of EV: driving range and safety.
Factorial’s development is based on Factorial Electrolyte System Technology (FEST), 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 designed to be safer than conventional lithium-ion technology, extends driving range, and is drop-in compatible for easy integration into existing lithium-ion battery manufacturing infrastructure.
“It is a great honour 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.”
In July, Stellantis announced its target of having the first competitive solid state battery technology introduced by 2026.
