Zusammenfassung:PURPOSE: A manufacturing method of a lithiated electrode material is provided to manufacture an electrode material consisting of uniform particles having sizes of 500 or less, and having relatively excellent performance in low temperatures. CONSTITUTION: A manufacturing method of a lithiated electrode material using polyol process comprises a step of manufacturing polyol reactant composition by adding transition metal compound, dissolving a lithium-based compound into a polyol solvent; a step of raising temperature of the manufactured polyol reaction composition to 240-260°C; a step of maintaining the risen temperature of the reactant composition, and cooling the reactant composition to generate the lithiated electrode material.
