Stellantis to unveil electric vehicle fleet with factorial’s solid-state batteries by 2026

Stellantis, the fourth largest automaker globally, announced plans to launch a demonstration fleet of electric vehicles (EVs) powered by solid-state batteries from US startup Factorial by 2026. This initiative was revealed during a joint statement on Wednesday, emphasising a significant step towards commercialising this innovative technology.

Solid-state batteries are anticipated to revolutionise the EV market by minimising fire risks, reducing vehicle weight, and lowering production costs while extending driving range on a single charge. As automakers strive to enhance vehicle performance amid stagnating EV sales, these advancements could be pivotal.

However, the journey to scale solid-state battery production has proven challenging for major manufacturers and their partners. Stellantis’ partnership with Factorial began in 2021, marked by a USD 75 million investment aimed at accelerating the development of this promising technology.

The upcoming demonstration fleet will feature the all-new Dodge Charger Daytona, built on Stellantis’ STLA Large platform, which also underpins larger models from brands such as Jeep, Chrysler, Alfa Romeo, and Maserati. This integration of Factorial’s batteries into the STLA Large platform is designed to enhance Stellantis’ electric vehicle offerings, aiming for improved performance, extended driving ranges, and quicker charging times in the future.

Ned Curic, Stellantis’ Chief Engineering and Technology Officer, emphasised the importance of this collaboration, stating, “By integrating Factorial’s innovative battery solution into the STLA Large platform, we are validating its potential to enhance our electric vehicle lineup.”

The STLA Large platform is poised to support the production of up to two million vehicles globally, aligning with Stellantis’ vision for high-volume electric SUVs and performance vehicles. As the automaker navigates the complexities of solid-state battery technology, this initiative could mark a transformative moment in the electric vehicle landscape.
