Abstract

The lithium-ion conductor contains a crystal structure whose composition formula is represented by LiPBS(0<x≦1). The crystal structure contains a LiStetrahedron and a BStetrahedron, a triangle window of the LiStetrahedron through which lithium ions pass becomes large caused by the BStetrahedron, and an ionic conductive path is expanded. Furthermore, lithium ions being a conductive carrier are added corresponding to B quantity x. Consequently, a lithium-ion conductor that exhibits excellent ion conductive property is realized. By using the lithium-ion conductor for a solid electrolyte, an all-solid lithium-ion secondary battery with high characteristics is realized.
