摘要：

Synthesis of single lithium-ion conducting polymer electrolyte membrane (SLIC-PEM) composed of polymerized lithium 4-styrenesulfonyl(trifluoromethylsulfonyl)imide (PLiSTFSI), poly-(ethylene glycol) methyl ether methacrylate (PEGM), poly(ethylene glycol) dimethacrylate (PEGDMA), and ethylene carbonate (EC) is reported. SLIC-PEM combines the advantages of single lithium-ion conducting polymer electrolytes, cross-linked flexible polymer electrolytes, and the liquid electrolyte of carbonate. The synthesized SLIC-PEMs have superior thermostability, high ionic conductivity, a wide electrochemical window, and high lithium-ion transference number. The corresponding LiFePO4 vertical bar SLIC-PEM vertical bar Li cell delivers high Coulombic efficiency and excellent discharge capacity and cycling performance, demonstrating that SLIC-PEMs will have promising application in next-generation safe lithium metal batteries.
