Taking the next step to advance the application of solid-state battery technology in EVs, Stellantis is incorporating Factorial’s solid-state batteries into a demonstration fleet of all-new Dodge Charger Daytona vehicles based on the STLA Large platform. This initiative builds upon the $75-million investment Stellantis made in Factorial in 2021.

These EVs will be on the road by 2026, representing a key next step in bringing solid-state battery technology to mass production.

Factorial will supply Stellantis with cells based on its proprietary FEST solid-state battery technology, which enables a specific energy density of more than 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.

Stellantis has selected the STLA Large multi-energy platform for this innovative technology due to its focus on high-volume electric SUVs and performance vehicles. The STLA Large platform, a cornerstone of Stellantis’ Dare Forward 2030 strategic plan, includes brands such as Jeep, Dodge, Chrysler, Alfa Romeo and Maserati. It is designed to support up to two million vehicles globally, making it suited for this innovative battery technology.

This demonstration fleet is an important milestone in our partnership with Factorial. 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.
