Abstract: Disclosed is a cathode active material for a lithium ion secondary battery which includes a lithium manganese borate compound and a manganese oxide. The lithium manganese borate compound contains a larger amount of lithium than conventional lithium manganese borate compounds. Therefore, a larger amount of lithium is deintercalated in a battery including the cathode active material, and as a result, the specific capacity of the battery reaches 100-160 mAh/g, which is much higher than that of conventional lithium ion secondary batteries (
