Abstract

A cathode material for sulfide-based all-solid-state batteries, in which Li3V2(PO4)3 (LVP) is doped with a transition metal having an oxidation number of +5 or more and the surface of the cathode material is substituted with a halogen element so as to have improved surface stability and energy density and to suppress side reactions with a solid electrolyte, a manufacturing method thereof, and an all-solid-state battery using the same.
