Stellantis and Factorial push solid-state batteries - Dodge demo fleet in 2026

The Stellantis Group and the US battery specialist Factorial aim to accelerate the development and use of electric vehicles with solid-state batteries. For this purpose, Stellantis had already invested 75 million US dollars in 2021. By 2026, a demonstration fleet of Charger Daytona vehicles from the Dodge brand is to be equipped with Factorial's solid-state batteries. This is said to be an important step in the commercialization of the promising technology, according to the group. The demo fleet aims to validate the technology and assess its performance under real driving conditions.

Factorial will supply Stellantis with cells based on its proprietary FEST solid-state battery technology. This enables a specific energy density of more than 390 Wh/kg (watt-hours per kilogram). They promise "significant advantages" over conventional lithium-ion batteries, including higher energy density, reduced weight, improved performance, and the potential to further reduce total vehicle costs over time.
