ANODE ACTIVE MATERIAL INCLUDING CARBON COMPOSITE FOR LITHIUM SECONDARY BATTERY AND METHOD OF MANUFACTURING THE SAME

An anode active material contains a carbon composite, and the carbon composite may include a core particle including hard carbon and a skin layer placed on a surface of the core particle. The skin layer includes graphite particles attached to the surface of the core particle at a predetermined angle with respect to the surface and the graphite particles include graphite-based carbon material. The skin layer further includes an amorphous carbon layer filling a space between the graphite particles and attaching the graphite particles to the surface of the core particle. The carbon composite has a ratio of Ito Iin a range of 0.8 to 1.5 (0.8≤I/I≤1.5) in Raman analysis where Iis the intensity of D peak at 1300 cmto 1400 cmand Iis the intensity of G peak at 1500 cmto 1600 cm.
