ABSTRACT:
The present invention relates to lithium manganese complex oxide with a spinel structure used as an active material of a lithium or lithium ion secondary battery. Specifically, the present invention relates to a process for preparing lithium manganese complex oxide having improved cyclic performance at a high temperature above room temperature, and a lithium or lithium ion secondary battery using the oxide prepared according to said process as a cathode active material.
