摘要： A positive electrode material for lithium secondary batteries capable of easily doping vanadium oxide with molybdenum, and a method of manufacturing the same are disclosed. The method of manufacturing a positive electrode material for lithium secondary batteries includes (a) reacting vanadium oxide with a water-soluble molybdenum-based compound in the presence of a solvent; and (b) thermally treating the reaction product of (a).
