An anode active material for lithium secondary battery includes a secondary particle formed by agglomerating primary particles, an average diameter of the primary particles is in a range from 5 μm to 15 μm, and an average diameter of the secondary particle is in a range from 10 μm to about 25 μm. The primary particles include an artificial graphite, and an I(110)/I(002) of the secondary particle is in a range from about 0.0075 to 0.012.
