Compatibility of Lithium Ion Conductive Sulfide Glass with Carbon-Lithium Electrode

Electrochemical properties of graphite were investigated using -based glass or -based glass as a solid electrolyte. Graphite showed reversible electrode reactions in the -based glass, while it did not in the -based one. The results of X-ray diffractometry and Raman spectroscopy indicated that the -based glass was reduced as side reactions instead of the intercalation of lithium ions into graphite during the reduction, resulting in the poor reversibility.
