Li⁺-migration influencing factors and non-destructive life extension of quasi-solid-state polymer electrolytes.

ABSTRACT: Polymer-based quasi-solid-state electrolytes (QSSE) are believed to be the most feasible candidates for solid-state batteries, but they are hindered by relatively lower ionic conductivity and narrower electrochemical window. Here, we synthesize a series of ether-free acrylates containing Li⁺-ligands for high-voltage-stable QSSEs. Our findings demonstrate that the polymer-involved solvation structure is critical in determining the ionic conductivity, and low-temperature crystallization of the polymer can be used for non-destructive life extension of batteries. The prepared polymers do not contain ether unit and exhibit a polymerization degree of 99% in cells without residual double-bonded monomer, endowing them with high antioxidation capability and compatibility with high-voltag
