PURPOSE: A manufacturing method of lithium-manganese oxide of excessive lithium and a secondary battery using thereof are provided to enhancing charge and discharge characters even in volume, variety, and velocity. CONSTITUTION: A manufacturing method of lithium-manganese oxide of excessive lithium is represented by chemical formula 1. The manufacturing method of lithium-manganese oxide of excessive lithium comprises the next steps: processing a reaction of lithium complex with lithium manganese based oxide which is represented by chemical formula 2 in reducing condition in order to synthesize lithium manganese based oxide; and synthesizing lithium manganese based oxide. The chemical formula 1 is same as follow: Li1+xMyMn2-yO4-zQz. The chemical formula 2 is same as follow: Li1+xMyMn2-x-yO4-zQ'z. |
