Room-temperature initiation enables uniform, 656.6 Wh kg⁻¹ solid-state Li batteries. A room-temperature free-radical polymerization strategy forms a uniform cathode electrolyte interphase (CEI) and a LiF-rich solid electrolyte interphase (SEI), preserving the stable lattice of the lithium-rich manganese-based oxide (LRMO) cathode. The resulting 9.53 Ah pouch cell with a high-areal-capacity cathode delivers 656.6 Wh kg⁻¹.
