Abstract

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 in situ polymerization on Li₆PS₅Cl. 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.
