Factorial's batteries will be fitted in a fleet of all-new Dodge Charger Daytona vehicles, which are based on Stellantis' STLA Large platform.
Stellantis will launch by 2026 a demonstration fleet of vehicles fitted with solid-state batteries from US startup Factorial, the two companies said.
The test fleet is a step toward potential commercialization of a technology that is aimed at improving EV performance.
Solid-state batteries are expected to reduce fire risk and allow for lighter, lower-cost cars that can travel further on a single charge. They are seen as a game-changing technology for electric vehicles, as automakers seek ways to cut costs and boost their range amid stagnating EV sales.
However, solid-state batteries are proving harder than expected for major automakers and battery making partners to develop at scale.
The test fleet is part of a partnership between Stellantis and Factorial, which began in 2021 with a $75 m investment made by the carmaker in the US firm.
The demonstration fleet will mark an important next step in the commercialization of the "promising" technology and help Stellantis assess its performance in real-world driving conditions, the two companies said in a joint statement on 23 October 2024.
Factorial's batteries will be fitted in a fleet of all-new Dodge Charger Daytona vehicles, which are based on Stellantis' STLA Large platform that is also used by large-sized models of other Stellantis brands including Jeep, Dodge, Chrysler, Alfa Romeo and Maserati.
"By integrating Factorial's innovative battery solution into the STLA Large platform, we are validating its potential to enhance our electric vehicle lineup, ensuring customers benefit from improved performance, longer driving ranges and faster charging times in the coming years," Stellantis' Chief Engineering and Technology Officer Ned Curic said.
Stellantis' STLA Large multi-energy platform is focused on high-volume electric SUVs and performance vehicles. It is designed to support up to two million vehicles globally, according to the automaker's plans, making it suited to the introduction of solid-state battery technology, the two companies said.
Advantages of solid-state batteries
Solid-state batteries replace the liquid electrolyte and the separator, which are both flammable, in a conventional lithium-ion battery with a solid separator made of ceramic, glass or polymers. They promise reduced charging times, longer driving ranges and no fire risk.
But no automaker has begun sales of EVs with solid state batteries yet and tests remain limited in scope and scale.
Factorial Energy aims to start mass production of its battery cells as soon as 2029, CEO Siyu Huang said.
The planned road tests of Stellantis vehicles will be conducted in the US, but Factorial did not specify where or how many vehicles will be involved.
Factorial's latest battery cell has an energy density of more than 390 watt-hours per kilogram, which would be higher than China's Contemporary Amperex Technology Co.'s Qilin condensed solid-state battery showcased in 2023.
Volkswagen earlier this year said it had achieved positive results with a prototype vehicle powered by a solid-state battery from partner QuantumScape. Other automakers dabbling independently in solid-state battery technology research include BYD and Nissan and Toyota.
Mercedes-Benz, Hyundai and Kia are also investors in Factorial.
