SULFIDE-BASED SOLID ELECTROLYTE USED FOR LITHIUM ION SECONDARY BATTERY AND PRODUCTION METHOD FOR SAME, SOLID ELECTROLYTE LAYER, AND LITHIUM ION SECONDARY BATTERY

SULFIDE-BASED SOLID ELECTROLYTE USED FOR LITHIUM ION SECONDARY BATTERY AND PRODUCTION METHOD FOR SAME, SOLID ELECTROLYTE LAYER, AND LITHIUM ION SECONDARY BATTERY

The present invention relates to a sulfide-based solid electrolyte used for a lithium ion secondary battery. The sulfide-based solid electrolyte comprises an argyrodite-type crystals represented by the composition formula Lia-M-Zb-Hac, in which M, Z, and Ha are at least one element selected from pre...

description The present invention relates to a sulfide-based solid electrolyte used for a lithium ion secondary battery. The sulfide-based solid electrolyte comprises an argyrodite-type crystals represented by the composition formula Lia-M-Zb-Hac, in which M, Z, and Ha are at least one element selected from predetermined elements; Z includes S; and a, b, and c of the composition formula represent the content ratio (unit: at%) of each element, and satisfy 5 < a < 7, 4 < b < 6, and 0 < c < 2. The maximum distance between the Li/Li-ions in the crystals is 2.54 Å or less.
