NASICON structred vanadium phosphate as cathode material for Mg rechargeable batteries

摘要

The purpose of the present invention is to provide a positive electrode material of a novel structure, which has high operating voltage and capacity, and has a diffusion path in which divalent Mg ions can be smoothly inserted and desorbed; and a manufacturing method thereof. To this end, the present invention relates to a positive electrode material for a magnesium secondary battery of vanadium phosphate having a NASICON structure. More specifically, provided is a positive electrode material for a magnesium secondary battery which can achieve high energy density by discharge voltage of high voltage.
