Abstract: A composite anode active material, a method of preparing the composite anode active material, and a lithium battery including the lithium battery. According to the method of preparing the composite anode active material, carbon nanotubes are formed on a Si particle without a separate operation of applying a catalyst. Furthermore, high adherence is provided between the Si particle and carbon nanotubes, and therefore the composite anode active material is used as an anode material of the lithium battery.
