Provided are conductive single crystal silicon particles coated with highly conductive carbon containing nanopores and an ultrathin metal film, a high capacity anode material including the same, and a preparing method thereof. The anode material includes conductive single crystal silicon particles each on which at least one element selected from group-III and group-V elements is doped; a thin metal layer formed to coat the surface of each of the conductive single crystal silicon particles; and a highly conductive carbon coating layer formed on the thin metal layer, wherein nanopores are formed between the conductive single crystal silicon particle and the carbon coating layer.
