PURPOSE: An anode active material, an electrode including the same, and a secondary battery including the electrode are provided to manufacture the electrode having excellent cycle property and electric capacity and to reduce volume expansion. CONSTITUTION: An anode active material comprises crystalline phase including Si and Si-metal alloy and amorphous phase including the Si and the Si-metal alloy. The Si-metal alloy of the crystalline phase and the Si-metal alloy of the amorphous phase are same or different. The metal of the Si-metal alloy is selected from Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Sr, Y, Zr, Nb, Ba, Lu, Hf, Ta, and element of lanthanum group. |
