Abstract

A cathode and a battery including a cathode active material including a layer-structured material having a composition of xLiMO-(1-x)LiMeO; and a metal oxide having a perovskite structure. The cathode active material may have improved structural stability by intermixing a metal oxide having a similar crystalline structure with the layer-structured material, and thus, life and capacity characteristics of a cathode and a lithium battery including the metal oxide may be improved.
