CATHODE, METHOD OF PREPARING THE SAME, AND LITHIUM BATTERY INCLUDING THE CATHODE

摘要

A cathode, a method of preparing the same, and a lithium battery including the cathode. The cathode includes: a current collector; a first cathode active material layer disposed on the current collector; and a second cathode active material layer disposed on the first cathode active material layer, wherein the first cathode active material layer comprises a lithium transition metal oxide having a layered structure, and the second cathode active material layer comprises a lithium transition metal oxide having a spinel structure and an average working potential of 4.5 V or more.
