Abstract
Official abstract text for this publication.
An ion conductive glass ceramics having the formula Na2S—P2S5, wherein the Na2S in the ion conductive glass ceramics is contained in an amount of from 70 to 75 mole %, and wherein the ion conductive glass ceramics has a state where crystal parts are dispersed in the glass ingredient of an amorphous state and where the crystal parts contain tetragonal Na3PS4.
First claim
Opening claim text (preview).
What is claimed is: 1. An ion conductive glass ceramics having a formula Na 2 S—P 2 S 5 , wherein the Na 2 S in the ion conductive glass ceramics is contained in an amount of from 70 to 75 mole %, and wherein the ion conductive glass ceramics has a state where crystal parts are dispersed in a glass ingredient of an amorphous state and where the crystal parts contain tetragonal Na 3 PS 4 . 2. The ion conductive glass ceramics of claim 1 , wherein the ion conductive glass ceramics is contained in a solid electrolyte layer of an all-solid-state secondary cell. 3. The ion conductive glass ceramics of claim 1 , wherein the crystal parts are contained in an amount of 50% by weight or more of the ion conductive glass ceramics. 4. An all-solid-state secondary cell comprising at least a positive electrode, a negative electrode and a solid electrolyte layer, wherein the solid electrolyte layer contains the ion conductive glass ceramics of claim 1 .
