Tóm tắt

Poly(vinylidene fluoride) (PVDF)-based solid-state electrolytes (SSEs) have been considered promising candidates for advanced Li metal batteries due to their adequate mechanical strength and acceptable thermal stability. However, the poor compatibility between residual solvent and Li metal inevitably leads to fast capacity decay. Herein, we propose a multifunctional cation-anchor strategy to regulate solvation chemistry in PVDF-based SSEs to boost the electrochemical performance of Li metal batteries. The strong interaction between
