Anode active material for secondary battery, method of preparing the same and secondary battery including the same

An anode active material for a secondary battery according to an embodiment of the present invention includes a core particle, a polymer coating formed on a surface of the core particle, and conductive particles formed on the polymer coating. The conductive particles have an average particle diameter greater than a thickness of the polymer coating. The anode active material and a secondary battery having improved stability and reduced resistance are provided using the polymer coating and the conductive particles.
