Solid-state electrolytes have the advantages of high thermal stability and good electrochemical stability. In this paper, a hybrid solid electrolyte was prepared by mixing and regulating the ratio of inorganic solid electrolyte and polymer electrolyte, and the HSE with 70% LATP content showed excellent electrochemical and physical properties. Analyzing the cycling products proved that our prepared layered HSE has a negative electrode protection. The assembled lithium–oxygen battery can be cycled up to 131 cycles at a current density of 0.1 mA·cm –2 and a specific capacity of 0.25 mAh·cm –2, which is expected to be a candidate for solid-state battery electrolytes.
