Abstract
Official abstract text for this publication.
The present invention relates to a nitrogen-doped sulfide-based solid electrolyte for all-solid batteries. The a nitrogen-doped sulfide-based solid electrolyte for all-solid batteries includes a compound with an argyrodite-type crystal structure represented by the following Formula 1:LiaPSbNcXd [Formula 1]wherein 6≤a≤7, 3≤b≤6, 0≤c≤1, 0≤d≤2, andeach X is the same or different halogen atom selected from the group consisting of chlorine (Cl), bromine (Br), and iodine (I).
First claim
Opening claim text (preview).
What is claimed is: 1. A solid electrolyte for all-solid batteries comprising: a compound represented by the following Formula 5: Li 6 PS 5−2d N d X 1+d [Formula 5] wherein in Formula 5, 0<d≤1; and each X is the same or different halogen atom selected from the group consisting of chlorine (Cl), bromine (Br), and iodine (I), wherein the compound has an argyrodite-type crystal structure. 2. An all-solid battery comprising: a cathode; an anode; and a solid electrolyte layer interposed between the cathode and the anode, wherein at least one of the cathode, the anode and the solid electrolyte layer comprises the solid electrolyte of claim 1 . 3. A method of manufacturing a solid electrolyte for all-solid batteries comprising: providing a mixture of Li 2 S, P 2 S 5 , LiX, and Li 3 N; grinding the mixture; and heat treating the mixture to obtain a compound having an argyrodite-type crystal structure, wherein each X is the same or different halogen atom selected from the group consisting of chlorine (CI), bromine (Br), and iodine (I), wherein the compound is represented by the following Formula 5: Li 6 PS 5−2d N d X 1+d [Formula 5] wherein in Formula 5, 0<d≤1; and each X is the same or different halogen atom selected from the group consisting of chlorine (Cl), bromine (Br), and iodine (I). 4. A vehicle comprising an all-solid battery of claim 2 .
