Abstract

Abstract : A BNNSs coating can form a robust protective layer on a PEO-based electrolyte to suppress the growth of Li dendrites and improve the performance of solid-state Li metal batteries. Abstract : Two-dimensional (2D) boron nitride nanosheets (BNNSs) were chemically exfoliated from bulk boron nitride and coated onto the surface of a poly(ethylene oxide) (PEO)-based electrolyte through a dry-pressing transfer process. The fabricated BNNSs coating formed a robust interfacial layer to improve the chemical and mechanical stability of the PEO-based electrolyte, leading to the enhanced performance of solid-state Li metal batteries.
