    Abstract: PURPOSE: A manufacturing method of a lithium manganese oxide electrode material is provided to manufacture a crystalline lithium manganese oxide electrode material using an amorphous lithium manganese oxide as a starting material. CONSTITUTION: A manufacturing method of a lithium manganese oxide electrode material comprises a step of obtaining a uniform mixture by mixing amorphous lithium manganese oxide; and a step of heat-treating the mixture under oxygen or air atmosphere. The molar ratio of lithium and manganese is 6:5-10:5, in the mixture. The mixing step comprises a dry ball-milling the amorphous lithium manganese oxide and lithium. The heat-treating step is conducted in a vacuum furnace at 400-900 deg. C for 8-20 hours.
