Abstract
The present invention relates to an anode active material for lithium secondary battery and a lithium secondary battery comprising the same. The anode active material for lithium secondary batteries comprises two kinds of crystalline carbon, with the peak intensity ratio of 3R(101) face to 2H(100) face I3R(101)/I2H(100) ranging from 0.55 to 0.7 in an X-ray diffraction pattern.
