Automotive giant Stellantis is collaborating with the startup Factorial Energy to integrate groundbreaking semi-solid state batteries into their high-performance electric vehicles. This innovative technology utilizes a lithium-metal anode to significantly increase energy density while enhancing safety by removing flammable liquid components. By testing these batteries in a pilot fleet of Dodge Charger Daytona models, the company aims to drastically extend driving range and reduce overall vehicle weight. These road tests, scheduled for 2026, will evaluate how the hardware performs under diverse environmental stresses and high-speed charging scenarios. Successfully validating this chemistry could provide Stellantis with a major competitive advantage over rivals by offering more efficient and reliable electric propulsion. If the trial succeeds, the company plans to scale this advanced power source across its luxury and utility brands, including Alfa Romeo and Jeep.
