Abstract

A composite anode active material includes a composite of a carbon-based anode active material, a metal-based anode active material and polymer particles. By increasing the conductivity of the composite anode active material, a lithium battery having a large capacity, high initial efficiency, high rate capability and improved cycle life performance can be obtained. An anode includes the composite anode active material and a lithium battery includes the anode.
