Abstract

The disclosure proposes a solid electrolyte membrane and a preparation method and an application thereof. The solid electrolyte membrane includes a binder and a sulfide solid electrolyte. The sulfide solid electrolyte has a molecular formula of Li<f>P<1-g>E<g>S<w>O<g>Q<z>, wherein, 5<f<10; 0<g<1, 3<w<6, 4<w+g<6, 0<z<2; E is selected from one or more of Mg, Ca, Sr, Ba, Zn, Cr, Sn or Pb; Q is selected from one or more of Cl, Br or I. Ionic conductivity of the solid electrolyte membrane is 1×10<-3>S/cm to 2×10<-2>S/cm. Through the solid electrolyte membrane and the preparation method and the application thereof proposed by the disclosure, the stability of the conductivity of the solid electrolyte membrane may be enhanced, the air stability may be enhanced, and the lifetime and safety of all-solid-state lithium-ion batteries may be improved.
