Solid-state battery maker Factorial Energy lists on Nasdaq after 745-mile Mercedes test
By Eve
US solid-state battery developer Factorial Energy has listed on Nasdaq to fund commercialisation, following a September real-world test in which a modified Mercedes-Benz EQS travelled over 745 miles (1,200 km) on a single charge using Factorial cells. Mercedes reported the solid-state pack delivered 25% more usable energy than a standard EQS battery at roughly the same weight and size. Factorial holds partnerships with Mercedes-Benz, Hyundai, Kia and Stellantis and plans to supply cells to defence, aerospace and robotics sectors alongside automotive.
Why it matters: A proven 745-mile range and 25% energy density gain signal that solid-state technology may soon reach commercial scale, potentially reshaping charging infrastructure demand as longer-range EVs reduce the frequency and density of charge points needed. Public funding via the Nasdaq listing accelerates the timeline for mass production, giving CPOs and network planners a clearer view of next-generation battery economics.
