POSITIVE ACTIVE MATERIAL, POSITIVE ELECTRODE, LITHIUM BATTERY INCLUDING THE SAME, AND METHOD OF MANUFACTURING THEREOF

摘要

Provided is a positive active material, a positive electrode including the positive active material, a lithium battery, and a manufacturing method of the same. The positive active material includes a core including a lithium nickel composite oxide and a coating layer formed on the core. The coating layer improves structural stability of the positive active material. Accordingly, lifespan properties of a lithium battery including the positive active material may be improved.
