SULFIDE GLASS AND CRYSTALLINE SOLID ELECTROLYTE PRODUCTION METHOD, CRYSTALLINE SOLID ELECTROLYTE, SULFIDE GLASS AND SOLID-STATE BATTERY

摘要

A sulfide glass production method in which phosphorus sulfide that satisfies formula (1) is used as a raw material. Formula 1: 100 × A/B ≥ 37 (In the formula, A represents the peak area of peaks appearing at peak positions in the ranges of 57.2-58.3 ppm and 63.0-64.5 ppm, in 31P NMR spectroscopy, and B represents the sum of peak areas of all the measured peaks.)
