Title:
SULFIDE SOLID ELECTROLYTE GLASS CERAMIC AND MANUFACTURING METHOD FOR SAME
Document Type and Number:
WIPO Patent Application WO/2023/190862
Kind Code:
A1
Abstract:
Provided is a sulfide solid electrolyte glass ceramic including lithium atoms, sulfur atoms, phosphorus atoms, and halogen atoms. In an X-ray diffraction measurement using CuKα rays, the diffraction angle (2θ) has peaks at 20.2° and 29.3°, a value (PA/PB) of an intensity ratio of a peak intensity (PA) of the peak appearing at 2θ = 20.2° to a peak intensity (PB) of the peak appearing at 2θ = 29.3° is set to greater than 1.0. As a result, this sulfide solid electrolyte glass ceramic has high ionic conductivity and improved water resistance. Provided also is a method for manufacturing the sulfide solid electrolyte glass ceramic.
