Stellantis & Factorial: Solid-State EV Battery Breakthrough

Stellantis and Factorial Energy have just revealed a massive milestone in electric vehicle technology: a validated solid-state battery capable of charging from 15% to 90% in about 18 minutes. With a density of 375 Wh/kg, this innovation could surpass traditional lithium-ion batteries, providing better range, faster charging, and improved safety.

The collaboration targets future Stellantis EVs, including the 2026 Dodge Charger Daytona, setting a new benchmark for electric mobility.

🚗 Learn how these solid-state batteries compare to current lithium-based ones in our article on Best Electric Vehicles 2025.

Solid-State Technology: What Sets It Apart?

Traditional lithium-ion batteries use liquid electrolytes, which present risks like overheating, flammability, and performance degradation. Solid-state batteries replace this liquid with solid electrolytes, offering:

• Higher energy density
• Faster charging
• Longer lifespan
• Improved safety

With 375 Wh/kg, Stellantis and Factorial’s battery represents one of the highest densities ever tested in a commercial-ready format.
