An anode active material for a lithium secondary battery having a high capacity and a high efficiency of charge discharge characteristics. The anode active material includes a silicon mono-phase and an alloy phase formed of silicon with a metal element at least one selected from the group consisting of Ti, Ni, Cu, Fe, Mn, Al, Cr, Co, and Zn. The anode active material is a powder in which the silicon mono-phase is uniformly distributed in a matrix of the alloy phase, has particle size distribution defined as D0.1 and D0.9, and the value of D0.1-D0.9 is in a range from about 3 mum to about 15 mum. |
