Document Type and Number:
WIPO Patent Application WO/2020/105736
Kind Code:
A1
Abstract:
Provided are: a sulfide solid electrolyte with an average grain diameter, measured by the laser diffraction grain size distribution measurement method, of at least 3 µm and a specific surface area, measured by the BET method, of at least 20 m2/g, the electrolyte being adjustable to have novel morphology or easily adjusted to obtain a desired morphology; and a treatment method for a sulfide solid electrolyte in which at least one mechanical treatment chosen from shredding and pelletization is applied to the aforementioned sulfide solid electrolyte.
