Abstract:
A method for preparing a lithium manganese oxide positive active material for a lithium ion secondary battery, which has spherical spinel-type lithium manganese oxide particles having two or more different types of sizes, the method including uniformly mixing manganese oxide having two or more different types of sizes with a lithium containing compound, and heat treating the resultant mixture to obtain lithium manganese oxide.
