Anode active material including carbon composite for lithium secondary battery and method of manufacturing the same

An anode active material comprising:

• a carbon composite, the carbon composite comprising:
• a core particle including hard carbon;
• and
• a skin layer placed on a surface of the core particle, wherein the skin layer comprises:
• graphite particles attached to the surface of the core particle and including graphite-based carbon material;
• and
• an amorphous carbon layer filling a space between the graphite particles and attaching the graphite particles to the surface of the core particle,
• wherein the carbon composite has a ratio of ID to IG in a range of 0.8 to 1.5 (0.8≤ID/IG≤1.5) in Raman analysis where ID is the intensity of D peak at 1300 cm−1 to 1400 cm−1 and IG is the intensity of G peak at 1500 cm−1 to 1600 cm−1, and
• 50% by weight or more of the graphite particles based on the total weight of the graphite particles are attached at an angle of about 20° to about 90° with respect to the surface of the core particle.
