Resumen de: EP4601063A1
A solid-state electrolyte membrane, a preparation method therefor, an all-solid-state battery and an electrical apparatus. The solid-state electrolyte membrane comprises a solid-state electrolyte and a ceramic fiber material dispersed in the solid-state electrolyte; the solid-state electrolyte comprises an inorganic solid-state electrolyte; when the diameter of the ceramic fiber material is denoted as D and the length of the ceramic fiber material is denoted as L, the diameter of the ceramic fiber material and the length of the ceramic fiber material satisfy: L/D ≥ 2. Since the ceramic fiber material is dispersed in the solid-state electrolyte, when the solid-state electrolyte membrane is fractured by the stress generated by electrochemical deposition, the ceramic fiber material around cracks may be pulled out or fractured so as to absorb a large amount of strain energy of the fracture, thus substantially increasing the difficulty of crack propagation, improving the fracture toughness of solid-state electrolyte membranes so as to enhance mechanical properties thereof and inhibit generation of lithium dendrites, and also significantly increasing the critical current density of the solid-state electrolyte membranes.
