Solid-state batteries replace the liquid electrolyte with a solid material, potentially enabling higher energy density, faster charging, and improved safety (no flammable liquid). Toyota has been the most publicly committed, announcing 2027-2028 targets for production vehicles. Samsung SDI, QuantumScape (Volkswagen-backed), Solid Power (BMW/Ford), and Factorial Energy (Mercedes/Stellantis) are the leading suppliers. The engineering challenges — lithium dendrite formation at the solid-solid interface, manufacturing scalability, and cycle life under real-world conditions — remain substantial. A realistic assessment of which companies have solved the key manufacturing problems and which timelines are credible based on disclosed test data.
