Abstract

A Li₆PS₅Cl-rich composite is prepared using a PEG-borate ester solid-state polymer electrolyte (BSPE). BSPE is a highly accessible compound with high ionic conductivity and excellent electrochemical stability against Li metal. Thereby, the stability of the Li₆PS₅Cl-rich composite with BSPE improved significantly.
