Document Type and Number:
WIPO Patent Application WO/2021/054412
Kind Code:
A1
Abstract:
Provided is a method for producing a crystalline solid electrolyte having a small grain diameter and high ionic conductivity and containing a lithium element, a sulfur element, a phosphorus element and a halogen element, the method comprising: a mixing step of producing a precursor containing a lithium element, a sulfur element and a phosphorus element, wherein the mixing step includes a complexation step of mixing a solid electrolyte raw material with a complexing agent in a liquid phase; and a crystallization step of heating the precursor in a solvent using a pressure-resistant container or under reflux.
