Title:
METHOD FOR PRODUCING SOLID ELECTROLYTE PARTICLES AND METHOD FOR PRODUCING ALL-SOLID-STATE BATTERY
Document Type and Number:
WIPO Patent Application WO/2022/215520
Kind Code:
A1
Abstract:
The present invention is able to provide a method for producing solid electrolyte particles, the method comprising a step (1) in which solid electrolyte particles are precipitated by bringing a good solvent solution and a poor solvent into contact with each other, the good solvent solution containing a good solvent and a solid electrolyte that contains elemental Sn, elemental S and at least one of an alkali metal element and an alkaline earth metal element. The present invention is also able to provide a method for producing an all-solid-state battery, the method comprising a step in which an all-solid-state battery is formed by stacking a solid electrolyte layer, which is formed using solid electrolyte particles produced by the above-described method, a positive electrode layer and a negative electrode layer.
