Stellantis looks to solid state batteries

Stellantis Group and Factorial Energy have announced the signing of a joint development agreement to advance Factorial’s high-voltage traction solid-state battery technology which also includes a strategic investment from Stellantis.  Of course, Stellantis the group name for light commercial vehicle brands of Peugeot, Citroen, Fiat and Vauxhall.

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

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.

“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.”

“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.”

Who are Stellantis ?

Stellantis are one of the world’s leading automotive manufacturers and a mobility provider which is the name for the recent amalgamation of the PSA Group, which owns Peugeot and Citroen and initially the Vauxhall / Opel group and then latterly this year ( 2021) the Fiat Group. This makes the company one of the largest global manufacturers with a presence in every major continent. .

Who are Factorial Energy?

Based in Woburn, Massachusetts, Factorial Energy has developed breakthrough solid-state batteries that offer 20 to 50 percent longer range per charge, increased safety, and cost parity with conventional lithium-ion batteries. The company’s proprietary FEST™ (Factorial Electrolyte System Technology) leverages a solid electrolyte material, which enables safe and reliable cell performance with high capacity cathode and anode materials. FEST™’s electrolyte has been successfully scaled in 40Ah cells, works at room temperature, and can utilise the majority of existing lithium-ion battery manufacturing equipment. The company is integrating its technology with several auto manufacturers.
