COMPOSITE ANODE ACTIVE MATERIAL, AND ANODE AND LITHIUM BATTERY INCLUDING COMPOSITE ANODE ACTIVE MATERIAL

A composite anode active material includes a first core and a coating layer on the first core, in which the coating layer includes an ion-conductive polymer and the amount of the ion-conductive polymer is from about 0.0001 wt % to about 0.04 wt % based on a total weight of the composite anode active material. A lithium battery including the composite anode active material may have improved thickness expansion rate, and enhanced initial efficiency and lifespan characteristics.
