      Stellantis and Factorial have successfully validated solid-state battery cells suitable for automotive use.

      These cells have an energy density of 375 Wh/kg and can charge from 15% to 90% in just 18 minutes.

      Prototypes of the Dodge Charger Daytona featuring these solid-state batteries are expected by 2026.

      Last fall, Stellantis and Factorial announced intentions to integrate solid-state batteries into a fleet of Dodge Charger Daytonas by 2026, and this project's progress is advancing as both companies have validated automotive-sized solid-state battery cells with a notable energy density of 375 Wh/kg.

      Though the technical details may be complex for many, the automaker confirmed that they validated 77Ah FEST (Factorial Electrolyte System Technology) cells over 600 cycles and are making strides toward automotive qualification, marking a significant milestone for large-format lithium-metal solid-state batteries.

      In addition to impressive energy density, solid-state batteries enable a significant decrease in charging times. Specifically, at room temperature, they can reach a charge of 15% to 90% in 18 minutes. These cells are also designed to provide high power output with discharge rates up to 4C, catering to the performance requirements of electric vehicles.

      While further work remains, Factorial’s latest electrolyte formula allows operation at temperatures ranging from -22°F to 113°F (-30°C to 45°C). This broad temperature range enables solid-state EVs to function in all but the most extreme weather conditions.

      Ned Curic, Stellantis' Chief Engineering and Technology Officer, stated, “This breakthrough positions us at the leading edge of the solid-state revolution, but we are not halting here. We are continually collaborating to push the limits and offer even more advanced solutions, moving us towards lighter, more efficient batteries that lower costs for our clients.”

      Factorial Energy CEO Siyu Huang echoed these thoughts, remarking, “Battery development involves trade-offs. While enhancing a single feature is straightforward, achieving a balance of high energy density, cycle life, rapid charging, and safety in an automotive-sized battery with OEM validation is a significant breakthrough. This accomplishment with Stellantis is transitioning next-generation battery technology from research to reality.”
