Abstract

Provided are a positive active material, a lithium battery including the positive active material, and a method of manufacturing the positive active material. The positive active material includes a lithium molybdate composite having a core-shell structure. The lithium molybdate composite acts as a sacrificial positive electrode in a positive electrode of a battery. The positive active material is able to increase charge capacity of a lithium battery, and accordingly is able to improve lifetime properties of a lithium battery.
