The 2026 Solid-State Battery Reality Check: What Actually Shipped
The 2026 solid-state battery reality check: what actually shipped. ProLogium began mass production of its Gen 3.5 all-solid-state battery at 381 Wh/kg, verified by TÜV and UL Solutions. Stellantis and Factorial launched North America’s first solid-state road test in a Dodge Charger Daytona. But CATL stated mass-market deployment is unlikely before 2030, Toyota delayed its production timeline to 2028, and no mass-market EV was equipped with a solid-state battery. This analysis breaks down what actually shipped, what remained in the lab, and the honest state of play.
