Title:
SOLID ELECTROLYTE, AND ELECTRODE MIXTURE, SOLID ELECTROLYTE LAYER AND BATTERY, EACH USING SOLID ELECTROLYTE
Document Type and Number:
WIPO Patent Application WO/2022/186303
Kind Code:
A1
Abstract:
This solid electrolyte contains elemental lithium (Li), an element M (M is composed of at least one element that is selected from among silicon (Si), antimony (Sb), tin (Sn) and germanium (Ge)), elemental sulfur (S) and iodine (I). The X-ray diffraction pattern of this solid electrolyte has a diffraction peak A within the range where 2θ is from 24.0° to 24.8°, a diffraction peak B within the range where 2θ is from 28.2° to 29.0°, and a diffraction peak C within the range where 2θ is from 29.5° to 30.3°. If Ia is the peak intensity of the diffraction peak A and Id is the peak intensity of a diffraction peak D that is within the range where 2θ is from 25.3° to 25.9°, Id/Ia is 0.05 or less.
