Abstract
The present disclosure relates to a sodium-ion storage material including a doped compound, and an electrode material for a sodium-ion battery, an electrode for a sodium-ion battery, and a sodium-ion battery, which include the sodium-ion storage material. Specifically, the sodium-ion storage material may include a compound consisting of an NaVM(PO)F/NaVM(PO)composite (M=Fe, Mn, Cr, Cu, Zn or Ti, 0<x,y≤2). When the sodium-ion storage material according to the present disclosure is used, it may maintain high discharge capacity while reducing the vanadium content, and when the sodium-ion storage material is applied to a sodium-ion secondary battery or a sodium-magnesium hybrid-ion battery, the battery may exhibit excellent charge/discharge cycle characteristics.
