Disclosed is a method of manufacturing a composite anode material for a lithium secondary battery containing nano-sized silicon and a carbonaceous material through a single process, the method including mixing a carbonaceous material and solid silicon and performing carbothermal shock for rapidly heating the carbonaceous material so that the solid silicon is melted using the heated carbonaceous material and is dispersed and attached in the form of particles to the surface of the carbonaceous material, the size of the silicon particles, which grow on the surface of the carbonaceous material, being adjusted during the carbothermal shock. Accordingly, processing costs can be lower than conventional methods of manufacturing silicon nanoparticles, and manufacturing costs can be further reduced by simultaneously performing formation of the silicon nanoparticles and compounding with the carbonaceous material.
