Stellantis N.V. (NYSE: STLA) and privately held Factorial Energy said today that their partnership to accelerate the development and deployment of next-generation electric vehicles (EVs) powered by Factorial’s solid-state battery technology* will begin with the launching of a demonstration fleet of all-new Dodge Charger Daytona vehicles based on the STLA Large platform incorporating solid-state batteries in 2026. Critics of solid state batteries maintain the thus far valid assertion that there is no clear path to mass production. Perhaps this will alter that perception at some pint in the future. However, demonstration fleets are not mass production. (read AutoInformed.com on: Solid-State Cell Technology – All Hype No Production Way?)*

“This demonstration fleet is an important milestone in our partnership with Factorial,” said Ned Curic, Stellantis’ Chief Engineering and Technology Officer. “By integrating Factorial’s innovative battery solution into the STLA Large platform, we are validating its potential to enhance our electric vehicle lineup, ensuring customers benefit from improved performance, longer driving ranges and faster charging times in the coming years.”

Factorial will supply Stellantis with cells based on its proprietary FEST® solid-state battery technology, which enables a specific energy density of over 390 Wh/kg. Factorial’s FEST® offers substantial advantages over traditional lithium-ion batteries including higher energy density, reduced weight, improved performance and a potential for further reduction in total vehicle cost over time. This makes it an ideal candidate for powering next-generation EVs. This builds upon the $75 million investment Stellantis made in Factorial in 2021.

“We are honored to be part of this journey with Stellantis to accelerate the adoption of electric vehicles,” said Siyu Huang, Factorial’s CEO and Co-Founder. “We believe solid-state technology can play a crucial role in enabling the next generation of EVs with improved performance and reduced costs.”
