Efficient Ion Migration and Stable Interface Chemistry of PVDF-Based Electrolytes for Solid-State Lithium Metal Batteries.

Poly(vinylidene fluoride) (PVDF)-based electrolytes with "Li salt-polymer-trace residual solvent" configuration have shown great potential in solid-state lithium metal batteries (SSLMBs). However, the interface failure initiated by the residual solvent and the sluggish Li migration kinetics caused by the intricacy of the Li-interaction environment severely precludes the large-scale commercial application of PVDF-based electrolytes in SSLMBs. Herein, the PVDF-based electrolytes are fabricated by compositing the PVDF matrix and sand-ground silicon monoxide (SiO-a) fillers with silicon monoxide/silicon-suboxide/silicon-dioxide (Si/SiO(0
