Solvation Regulation Reinforces Anion‐Derived Inorganic‐Rich Interphase for High‐Performance Quasi‐Solid‐State Li Metal Batteries

Solid-state polymer lithium metal batteries are an important strategy for achieving high safety and high energy density. However, the issue of Li dendrites and inherent inferior interface greatly restricts practical application. Herein, this study introduces tris(2,2,2-trifluoroethyl)phosphate solvent with moderate solvation ability, which can not only complex with Li
