Stellantis has confirmed it will integrate Factorial's quasi-solid-state battery technology into its high-performance electric vehicle, the Dodge Charger Daytona EV. A fleet of demonstration vehicles using the new battery will be on the road starting in 2026. According to the company, this battery is lighter, safer, and has a significantly higher energy density than current liquid anode lithium-ion batteries, promising improved overall performance, extended driving range, and shorter charging times.
Battery FEST on Charger Daytona EV: focus on energy density
In the Charger Daytona EV prototypes tested, Factorial's solid-state battery achieved an energy density of over 390 Wh/kg, far exceeding the 200–300 Wh/kg of commercially available lithium-ion batteries. This is a significant difference toward the goals of reducing weight, increasing energy storage capacity, and enhancing operational safety.
Stellantis stated that integrating the FEST battery into the STLA Large platform will improve overall vehicle performance, enhance range, and reduce charging times. Technical Director Ned Curic called this a “significant milestone” in their collaboration with Factorial.
Deployment roadmap: demonstration fleet to begin in 2026
The lineup of vehicles showcasing semi-solid-state batteries is expected to be operational by 2026, marking a concrete step in the commercialization of a technology that has been anticipated for over a decade. Stellantis has not yet announced the number of vehicles in this lineup, nor the timeframe for when customers can purchase vehicles equipped with solid-state batteries.
Supply chain and costs: upgrading existing production lines.
FEST (Factorial Electrolyte System Technology) is designed to integrate with existing lithium-ion battery production lines, reducing the need for new plant construction and potentially shortening the time and cost of production expansion. Factorial is currently operating a large-scale solid-state battery production line in Methuen, Massachusetts, with a completed capacity of 200 MWh per year.
The problem of scaling up: a major but feasible challenge.
The key challenge for solid-state batteries lies in the speed of production scaling. Instead of building new factories from scratch, Factorial's approach of upgrading its lithium-ion production lines is expected to solve the scaling problem more quickly. Stellantis, along with Mercedes-Benz and Hyundai Motor Group, have invested hundreds of millions of dollars in Factorial, demonstrating their commitment to making solid-state the next leap forward for electric vehicles.
Spread capability on STLA Large system
The STLA Large platform is currently being used by Jeep, Alfa Romeo, Chrysler, and Maserati. If production scales up as planned, solid-state battery EVs from these brands could soon appear, expanding the reach of FEST technology within the Stellantis ecosystem.

Conclude
The integration of Factorial's semi-solid-state batteries into the Charger Daytona EV lays a crucial foundation for improving performance, range, and charging times. Leveraging existing lithium-ion production lines and expanding manufacturing capabilities in the U.S., Stellantis is taking a substantial step toward commercializing solid-state batteries. Once expansion proceeds as planned, this technology could quickly spread to other EVs based on the STLA Large platform.
