Solid-state electrolytes based on in situ ring-opening polymerization of 1,3-dioxolane (DOL) have attracted widespread attention Li metal batteries because their high interface compatibility. However, its conventional cationic mechanism frequently results the formation long polymer chains during polymerization, thereby impeding Li+ transport. Here, we regulate ring opening DOL by introducing N,N-dimethyltrifluoroacetamide (FDMA), thus avoiding chains. Meanwhile, FDMA can derive a stable SEI rich LiF electrochemical cycling, improving stability and suppressing dendritic growth. Therefore, full battery with LiFePO4 as cathode achieve capacity retention rate 83.9% after 400 cycles at 5.0 C. At -20 °C, Li∥LiFePO4 provide 137 mAh g-1. The solvent-induced strategy provides promising new avenue for designing solid electrolyte temperature resistance.
