Title:
LITHIUM-ION-CONDUCTIVE GLASS MATERIAL
Document Type and Number:
WIPO Patent Application WO/2023/248921
Kind Code:
A1
Abstract:
Provided is a lithium-ion-conductive glass material from which a solid electrolyte having both a high density and a high lithium-ion conductivity can be formed by sintering a mixture thereof with a lithium-ion-conductive material at 700°C or lower. The lithium-ion-conductive glass material comprises, in terms of oxide amount in mol%, 43.5-49.0% P2O5 component, 0.5-4.0% Al2O3 component, and 47.0-55.0% Li2O component.
