PREPARATION METHOD FOR COMPOSITE SOLID-STATE ELECTROLYTE MEMBRANE

Resumen de: WO2026222950A1

The present invention relates to the field of solid-state batteries, and discloses a solid-state electrolyte membrane and a preparation method therefor, a battery, and a device. The solid-state electrolyte membrane comprises a sulfide fibrous electrolyte membrane, and a polymer electrolyte and a lithium salt dispersed in the sulfide fibrous electrolyte membrane. The sulfide fibrous electrolyte membrane is a thin film having a three-dimensional fibrous network structure prepared from an inorganic sulfide electrolyte by means of electrospinning technology. An ion-conducting polymer and a lithium salt are introduced into the sulfide fibrous electrolyte membrane through simple soaking and drying for filling. The introduction of the ion-conducting polymer can improve the mechanical strength of a composite electrolyte membrane; and thus the sulfide fibrous electrolyte is not easily broken, which eliminates the need for a binder and effectively avoids the problem that sulfide electrolyte particles are surface-coated by the binder, which would otherwise hinder lithium-ion transport. Meanwhile, the introduction of the lithium salt in the sulfide fibrous electrolyte membrane can enhance the ionic conductivity.
