Dodge Set On Real-World Tests For Solid-State Batteries In 2026

Following up on our earlier coverage of Stellantis’ collaboration with Factorial for solid-state battery technology, there's now confirmation that the Dodge brand will officially take part in real-world testing.

This development was recently highlighted in a feature by Carscoops, marking a significant step forward in the project’s trajectory. Stellantis - and especially Dodge - could use a breakthrough right now and solid-state batteries may be just the ticket.

Factorial, the startup behind this next-gen tech, has been technically working with Stellantis since 2021, but this marks the first time Dodge-branded vehicles will hit public roads equipped with the new battery tech.

Beginning in 2026, Dodge will launch a test fleet of Chargers powered by Factorial’s solid-state batteries. This real-world testing phase aims to iron out issues and optimize performance as the companies move toward potential production deployment between 2028 and 2032.

Factorial CEO Siyu Huang called the move a “very important milestone for cell performance validation,” emphasising that the focus isn’t just on energy density but also on battery life cycle and fast charging.

According to the company, the batteries deliver 375 Wh/kg and can charge from 15 to 90 percent in just 18 minutes.

Benefits of the solid state also include greater energy density, which translate into more range or alternatively, allow automakers to use smaller and lighter battery packs without sacrificing performance.

Safety is another key selling point. By using a solid, non-flammable electrolyte, these batteries reduce the fire risk issues of thermal runaway that are often associated with conventional lithium-ion packs.

While Stellantis is a major partner, Factorial is also collaborating with Kia, Hyundai, and Mercedes-Benz - the latter of which began road testing the tech earlier this year.

The Mercedes-Benz EQS fitted with a 450 Wh/kg density prototype pack reportedly delivered up to 1,000 km of range - around 25% more than the regular model equipped with a 118 kWh lithium-ion battery.

With faster charging, improved safety, and the potential for longer range or lighter EVs, the implications are big. For Dodge, it’s more than a tech upgrade - it might be the jumpstart the brand has been waiting for.
