PURPOSE:To maintain a high discharging capacity, and to improve the cycle characteristic by mixing the lithium compound with LiMnO4, and heat-treating this mixture within a specified temperature range to form the positive electrode active material. CONSTITUTION:The mixture of lithium compound with LiMn2O4 is heat-treated within a temperature range at 400-1325 deg.C to obtain the complex of lithium- manganese oxide and Li2MnO3 having the spinel structure. A positive electrode 4 having this complex as the positive electrode active material, a negative electrode 1 having lithium as the active material thereof, the non-aqueous electrolyte and a separator 7 are provided to form a secondary battery. A battery having the excellent cycle characteristic is thereby obtained. |
