Solid-State Batteries Power First Electric Car in North America

The future of electric cars just went from the lab to the highway, and it happened faster than anyone expected.

Stellantis and Factorial Energy began road testing the first solid-state battery-powered electric vehicle in North America this month, using a modified Dodge Charger Daytona as their proving ground. The milestone marks a turning point for an industry that's been promising revolutionary batteries for years.

The numbers tell an incredible story. Factorial's solid-state cells charge from 15% to 90% in just 18 minutes, nearly half the time of today's fastest charging systems. They deliver over 600 miles of range per charge, double what most current electric vehicles offer. Perhaps most impressively, they work in extreme conditions, from 22 degrees below zero to 113 degrees Fahrenheit.

Getting there wasn't simple. Engineers from both companies spent months developing new control systems and redesigning the battery pack to safely integrate the advanced cells into Stellantis' STLA Large platform. Every component had to be reimagined for a technology that replaces the liquid electrolyte in traditional batteries with a solid material.

"What we have built together is exactly the kind of deep, full-stack collaboration that solid-state has always required," said Siyu Huang, Factorial's CEO. The partnership demonstrates how legacy automakers and startups can move cutting-edge technology from theory to reality.

The Ripple Effect

Factorial isn't keeping this breakthrough to themselves. The company is working with Mercedes-Benz, Hyundai, and Kia to bring solid-state batteries to their vehicles too. Last September, a modified Mercedes EQS drove 745 miles on a single charge using Factorial's cells, proving the technology works across different vehicle platforms.

The impact extends beyond passenger cars. Factorial plans to adapt their battery technology for robotics, aerospace, and defense applications, potentially revolutionizing how everything from drones to spacecraft stores energy.

This week, Factorial began trading on the Nasdaq stock exchange following a merger valued at $1.3 billion, giving the company roughly $110 million to accelerate production. Major automakers are betting big that solid-state batteries will solve the range anxiety and charging time concerns that still keep some drivers from going electric.

The road testing happening right now in North America represents years of research compressed into a single, functioning battery pack powering a real car on real roads.
