Solid-State EV Batteries Hit North American Roads

The future of electric vehicles just rolled onto North American roads, and it could change everything about how we drive.

Stellantis and Factorial Energy made history this month by testing solid-state batteries in a Dodge Charger Daytona development vehicle. This marks the first time anyone has successfully integrated this advanced battery technology into an electric car driving on North American streets.

The numbers are impressive. Factorial's solid-state cells charge from 15% to 90% in just 18 minutes, roughly the time it takes to grab lunch. The batteries maintain their performance in brutal conditions, working perfectly in temperatures from -22°F to 113°F.

Even better, these batteries deliver 50% more range than current EV batteries. That translates to over 600 miles on a single charge, more than enough to drive from Los Angeles to San Francisco and back without stopping.

Getting this technology from the lab to the road took serious engineering. Factorial's CEO Siyu Huang explained that moving solid-state batteries into real vehicles required deep collaboration between companies, rewriting everything from cell chemistry to pack architecture.

The breakthrough builds on earlier success. Last April, Stellantis and Factorial proved their batteries could handle over 600 charge cycles while maintaining an energy density of 375 Wh/kg, a critical milestone for commercial viability.

The Ripple Effect

This advancement reaches far beyond electric cars. Mercedes-Benz already drove a modified EQS over 745 miles last September using Factorial's batteries, calling the technology a potential "gamechanger" for the entire automotive industry.

Major automakers are taking notice. Mercedes-Benz, Hyundai, Kia, and Stellantis have all partnered with Factorial to bring solid-state batteries to market. The technology could also revolutionize robotics, aerospace, and defense applications where weight and performance matter.

Factorial recently went public on Nasdaq under the ticker FAC, raising $110 million to commercialize their next-generation batteries. The company's merger valued the business at $1.3 billion, reflecting investor confidence in solid-state technology.

The road testing phase means we're closer than ever to seeing these batteries in production vehicles, potentially solving two of the biggest concerns holding people back from electric vehicles: range anxiety and charging time.
