摘要： A high capacity lithium secondary battery includes a lithium manganese oxide having a layered structure exhibiting a great irreversible capacity in the event of overcharging at a high voltage and a spinel-based lithium manganese oxide. Because it is activated at a high voltage of 4.45 V or higher based on a positive electrode potential, additional lithium for utilizing a 3V range of the spinel-based lithium manganese oxide can be provided and an even profile in the entire SOC area can be obtained. Because the lithium secondary battery includes the mixed positive electrode active material including the spinel-based lithium manganese oxide and the lithium manganese oxide having a layered structure, and is charged at a high voltage, its stability can be improved. Also, the high capacity battery having a large available SOC area and improved stability without causing an output shortage due to a rapid voltage drop in the SOC area can be implemented.
