摘要：
The present invention relates to a lithium manganese composite oxide and a method for preparing the same, and more particularly, to a lithium manganese composite oxide and a method for preparing same, in which a wet-milling process and a spray-drying process are applied, and the abundance ratio of Mn3+ ions to Mn4+ ions at the surface of the composite oxide is adjusted by controlling an oxidizing atmosphere during heat treatment.
