Stellantis and Factorial Energy have signed a joint development agreement to advance Factorial’s high-voltage traction solid-state battery technology.
The agreement also includes an unspecified investment from Stellantis.
“Our investment in Factorial and other 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, which addresses issues such as driving range and safety.
For his part, Factorial Energy co-founder and CEO, Siyu Huang, added: “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.
“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 programme 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 solid electrolyte material that enables cell performance with high-voltage and high-capacity electrodes and has been scaled in 40Ah cells that perform at room temperature.
Stellantis notes 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.
