Efficient Ion Migration and Stable Interface Chemistry of PVDF‐Based Electrolytes for Solid‐State Lithium Metal Batteries (Small 35/2025)

Lithium Metal Batteries 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 development of PVDF-based electrolytes. Herein, the PVDF-based electrolytes are designed by compositing the PVDF matrix and sand-ground SiO (SiO-a) fillers with Si/SiOx(0≤x≤2)/SiO2 heterostructure, SiO-a doping effectively deconstructs intrinsic Li+-solvent cage and establishes a stable electrode/electrolyte interface in the PVDF-based electrolyte.
