A ternary-salt solid polymer electrolyte (TS-SPE) consisting of LiPF-LiTFSI-LiFSI salts and poly(1,3-dioxolane) is created by polymerization. The TS-SPE possesses high ionic conductivity, high Li ion transference number, and stable SEI with low interfacial impedance, thereby realizing excellent rate performance and long-life stability in Li metal batteries.
