For years, solid-state batteries have been the elusive “next big thing” in electric vehicle (EV) technology, with critics often claiming that they’re perpetually five years away from reality. Now, that timeline has rapidly shrunk, as Stellantis aims to bring this game-changing technology to its Dodge Charger Daytona EV test fleet as early as 2026. This marks one of the first tangible moves toward integrating solid-state batteries into real-world automobiles, even if only in prototypes for now.
Stellantis has partnered with Factorial, a leader in solid-state battery (SSB) development, to equip these iconic muscle cars with the futuristic batteries. The new technology, which replaces the liquid electrolyte in traditional lithium-ion batteries with a solid substance, promises to revolutionize EV performance. Solid-state batteries allow for the use of more potent anode materials, translating into much higher energy densities. Factorial claims their cells can reach up to 390 watt-hours per kilogram (wh/kg), a significant leap compared to the 280 wh/kg achieved by GM’s current pouch cells.
This move by Stellantis is a bold leap ahead of other automakers dabbling in solid-state technology. While companies like QuantumScape, which partners with Volkswagen, and Solid Power, which collaborates with Ford and BMW, have been working on solid-state cells, Stellantis is the first to officially announce a test fleet with these cutting-edge batteries. Although Solid Power hinted at a BMW prototype featuring their cells, Stellantis is charging forward, with Dodge’s Charger Daytona EV being the first widely-publicized vehicle to feature solid-state batteries in its powertrain.
The Charger Daytona EV’s test fleet, expected to debut in 2026, will likely use Factorial’s 100 amp-hour cells, already distributed to automakers. However, the specifics of the battery pack configurations remain under wraps. What is clear is that Stellantis is making a significant statement in the EV race, signaling a move towards not only faster and more powerful EVs but also more efficient ones.
This collaboration could spark a wave of similar announcements across the industry. Mercedes-Benz, another automaker with an investment in Factorial, may be next in line to announce its own advancements in solid-state technology.
The introduction of solid-state batteries to the automotive world marks a potential breakthrough in EV performance, offering greater range, faster charging times, and enhanced safety. For Stellantis and Dodge, this development could redefine the future of electric muscle cars, setting a new standard for performance and efficiency.
