Lithium ion conductive material, lithium ion conductive solid electrolyte using the lithium ion conductive material, electrode protective layer for lithium ion battery, and method for producing the lithium ion conductive material

摘要

A method for manufacturing the lithium ion conductive substance is provided that includes the following steps: (a) a step of forming an inorganic substance that contains predetermined quantities of a Li component, an Al component, a Ti component, a Si component, and a P component, into a sheet shape, and (b) a step of interposing between materials that contain at least one kind of element selected from Zr, Hf, Y, and Sm, and sintering, a sheet-shaped formed body obtained at step (a).
