MANGANESE OXIDE, LITHIUM MANGANESE COMPLEX OXIDE AND COBALT-COATED LITHIUM MANGANESE COMPLEX OXIDE, AND PREPARATION PROCESSES THEREOF |
摘要 |
A manganese oxide which has a calcium or/and magnesium content of 0.01 to 2.50 mol % based on the moles of manganese, a lithuim manganese complex oxide using the manganese oxide, and a cobalt-coated lithuim manganese complex oxide are disclosed. These provide a particularly high discharge capacity and are useful for the improvement of cycle characteristics of a secondary battery as an active material of a positive electrode for a secondary battery with a nonaqueous electrolyte. |
