by Dodge and Factorial test solid-state batteries
Stellantis, particularly its Dodge brand, currently needs a successful technological breakthrough. Solid-state batteries could be the solution. Factorial, a company specializing in the development of such batteries, is collaborating with Dodge to test them in real-world conditions. If everything goes according to plan, Dodge vehicles with this technology could appear between 2028 and 2032.
The companies have been working together since 2021, but now, for the first time, Dodge will begin testing prototypes on public roads. Starting in 2026, they plan to release a batch of Chargers equipped with Factorial’s solid-state batteries to identify and address any shortcomings.
A significant step for electric vehicles
“What has happened with Stellantis is a very important milestone in verifying battery performance,” said Factorial CEO Siyu Huang. “It’s not just about higher energy density but also durability and charging speed. This is the first full-scale test shared by automakers.”
Solid-state batteries enable faster charging—from 15% to 90% in 18 minutes. They also have higher energy density, allowing for increased range compared to conventional batteries. Additionally, manufacturers can install smaller and lighter batteries while maintaining an acceptable level of autonomy.
Factorial has also made progress in battery performance at low temperatures. Their technology demonstrates stability even at -30°C. Importantly, solid-state batteries are safer due to the use of non-flammable electrolytes.
Besides Stellantis, Factorial collaborates with Kia, Hyundai, and Mercedes-Benz. The latter is also testing these batteries. If successful, solid-state batteries could become the standard, offering greater range, faster charging, and reduced weight. Successful testing could accelerate the market introduction of this technology.
Despite optimistic forecasts, mass production of solid-state batteries remains a complex challenge. Road testing will help determine whether the technology is ready for mass adoption. If the results are positive, it could significantly accelerate the transition to electric vehicles.
