Document Type and Number:
WIPO Patent Application WO/2024/045723
Kind Code:
A1
Abstract:
Provided in the present invention is a preparation method for a nanoscale sulfide solid electrolyte material. The preparation method comprises the following steps: 1) preparing a lithium sulfide material; 2) mixing in a sealed container 10-100 parts by weight of a solvent, 0-1 part by mass of a dispersing agent and 1 part by weight of a raw material containing the lithium sulfide material, and drying same to obtain an electrolyte precursor powder; and 3) carrying out heat treatment on the electrolyte precursor powder obtained in step 2), and crushing and milling same to obtain a nanoscale sulfide solid electrolyte material. The present invention uses simple preparation techniques, and the dimension of the prepared electrolyte can reach the nanoscale.
