Mercedes-Benz Road Tests Semi-Solid-State Batteries, Achieving 620+ Mile Range
2025-03-13
Mercedes-Benz and Factorial Energy are road-testing semi-solid-state batteries in the EQS electric sedan. These batteries, featuring a gel or liquid-infused solid electrolyte, boast an energy density of 391 Wh/kg, enabling a range exceeding 620 miles – a 25% increase over comparable traditional lithium-ion batteries. Crucially, the technology is compatible with existing production lines, making large-scale adoption feasible. With a projected showroom debut by 2030, this innovation promises to revolutionize electric vehicles and other applications.
