Title:
ELECTRODE COMPOSITE MATERIAL AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2021/029229
Kind Code:
A1
Abstract:
Provided are: an electrode composite material which is capable of exhibiting high battery performance and comprises a specific crystalline sulfide solid electrolyte and an electrode active material; and a method for manufacturing an electrode composite material, comprising the steps of: carrying out a first mixing of a complexing agent and a raw material-containing substance containing at least one selected from lithium element, sulfur element, and phosphorus element to obtain an electrolyte precursor; heating and decomplexing the electrolyte precursor; and carrying out a second mixing of a decomplexed product obtained by the decomplexation and an electrode active material.
