Electrochemical Oscillatory Screening Anion to Form LiF‐Rich SEI for Enhanced Stability of Silicon Anode (Small 49/2025)

Year: 2025

Type: article

Abstract: Silicon Anodes In article number 2509381, Huaping Wang, Hailong Wang, and co-workers reported a pulsed-voltage oscillatory screening strategy to regulate anion solvation sheaths. This approach enabled the construction of a LiF-rich bilayer solid electrolyte interphase (SEI) on silicon anodes. The resulting SEI exhibits high mechanical stability and rapid lithium-ion transport kinetics, achieving an initial Coulombic efficiency of 90.8% and enhanced capacity retention for the silicon anode.
