On April 24, The Verge reported that Stellantis—the multinational automotive giant behind brands like Jeep, Dodge, and Ram—has achieved a significant milestone in its quest to bring solid-state batteries to market. This breakthrough comes from a collaboration with battery startup Factorial.
The validated battery cell, which incorporates Factorial’s proprietary Electrolyte System Technology, boasts impressive specifications. It features a 77Ah cell that combines a lithium-metal anode, a semi-solid electrolyte, and a high-capacity cathode to achieve an energy density of 375Wh/kg.
This cutting-edge battery can endure over 600 charge and discharge cycles while maintaining stable performance across a wide temperature range, from -22°F to 113°F (-30°C to 45°C). This resilience ensures consistent operation in both frigid winters and scorching summers.
One standout feature is its exceptional fast-charging capabilities, charging from 15% to 90% capacity in a mere 18 minutes. This rapid charging feature is to boost the appeal of electric vehicles (EVs). Stellantis plans to debut this groundbreaking solid-state battery technology in the upcoming Dodge Charger Daytona, slated for release next year.
The race to commercialize solid-state batteries is heating up across the automotive industry. Hyundai and Mercedes-Benz—both investors in Factorial—are targeting 2026 for their solid-state battery rollouts. Meanwhile, Toyota has set its sights on 2028 to launch a solid-state battery capable of powering vehicles for up to 621 miles on a single charge. However, U.S. automakers may face stiff competition from Chinese companies like CATL and BYD, which have already introduced ultra-fast charging technologies, capable of adding significant range in just five minutes.
