The conglomerate has been in partnership with Factorial for the development of a solid-state battery for quite some time now
Stellantis is almost ready with its solid-state battery, which it is creating with Factorial. In fact, the plan is to equip a fleet of Dodge Charger Daytona cars with it by 2026. In this direction, the two companies have successfully validated automotive-sized solid-state battery cells. These boast an energy density of an impressive 375 Wh/kg. Stellantis clearly believes this will transform the industry going forward.

Stellantis Close To Launching Solid-State Battery
As per the details, the auto giant validated the 77Ah FEST (Factorial Electrolyte System Technology) cells over 600 cycles. With this, they are progressing towards automotive qualification. In fact, 600 cycles is a milestone for large-format lithium-metal solid-state batteries in itself. These batteries not only offer increased energy density but also enable reduced charging times. That is something absolutely crucial for the end users.
Furthermore, at room temperature, these batteries can go from 15% to 90% in a matter of 18 minutes. Also, the cells promise high power output with discharge rates up to 4C. The electrolyte formula ensures the operational temperatures to be between -22°F and 113°F (-30°C and 45°C). That should cover most scenarios in most parts of the world, including extreme conditions.
On this occasion, Stellantis Chief Engineering and Technology Officer, Ned Curic, said, “This breakthrough puts us at the forefront of the solid-state revolution, but we are not stopping there. We continue working together to push the boundaries and deliver even more advanced solutions, bringing us closer to lighter, more efficient batteries that reduce costs for our customers.”
Similarly, the Factorial Energy CEO Siyu Huang remarked, “Battery development is about compromise. While optimizing one feature is simple, balancing high energy density, cycle life, fast charging, and safety in an automotive-sized battery with OEM validation is a breakthrough. This achievement with Stellantis is bringing next-generation battery technology from research to reality.“
