Stellantis validates Factorial Energy’s solid-state battery tech for 2026 Dodge Charger, promising 500+ mile range and rapid charging amid global EV battery competition.
Stellantis has confirmed the validation of Factorial Energy’s 100 Ah solid-state battery cells, targeting integration into the electric Dodge Charger by 2026. The technology promises 50% higher energy density than current lithium-ion batteries, enabling ranges over 500 miles and sub-15-minute charging—a potential game-changer in the EV market.
Stellantis Bets Big on Solid-State Breakthrough
Stellantis announced this week the successful validation of Factorial Energy’s 100 Ah solid-state battery cells after rigorous testing at its facilities. According to the automaker’s technical report, the cells demonstrated 50% higher energy density than conventional lithium-ion batteries currently used in EVs. This achievement clears a critical path for the technology’s deployment in the 2026 Dodge Charger Daytona—the first production vehicle slated to use Factorial’s system.
“Our testing confirms these cells meet the safety, performance, and durability thresholds for automotive applications,” stated Stellantis’ Chief Engineering Officer in the June 27 press release. The company highlighted the battery’s ability to maintain stable operation across 1,000 charge cycles while supporting ultra-fast charging capabilities.
The Geopolitical Battery Race Intensifies
This development comes as the U.S. Department of Energy allocated $92 million in June 2024 to accelerate domestic solid-state battery development—a direct response to Asia’s dominance in lithium-ion production. Factorial Energy, which secured $200 million in Series D funding earlier this month, operates one of few U.S.-based facilities capable of pilot-scale solid-state production.
“Stellantis is playing catch-up with Tesla and BYD, but solid-state could be their trump card,” noted BloombergNEF’s energy storage analyst. “If they commercialize this by 2026, it would put them at least a year ahead of Toyota’s revised timeline.” The Japanese automaker recently pushed back its solid-state EV launch to 2027-2028, citing electrolyte stability challenges.
Challenges on the Road to 2026
Despite the progress, industry observers point to unresolved supply chain hurdles. Factorial’s technology relies on lithium-metal anodes—materials facing global shortages as demand outpaces mining capacity. Stellantis has not disclosed full details about its anode sourcing strategy.
Historical context underscores the significance: Previous battery innovations like lithium-ion took nearly 15 years from lab to mass production. However, with DOE backing and automakers desperate for range breakthroughs, the industry is compressing development timelines. The 2026 target remains aggressive but increasingly plausible given recent advancements.
