In situ constructed polymer-layer-modified solid electrolyte enables high-performance all-solid-state batteries

Side reactions between electrolyte and anode hinder the application of solid-state batteries. Here, a polymer-containing composite solid-state electrolyte (LiPSCl@PCSSE) was obtained through polymerization on Li PS Cl. The novel electrolyte was indicated to inhibit side reactions, and the pouch cell showed excellent performance, demonstrating its practical application owing to the employment of LiPSCl@PCSSE.
