The method of preparing the anode material includes: drying a first mixture including graphite balls, a nano-silicon slurry, pitch, and flake graphite to prepare a dried product; sintering the dried product to prepare a sintered product including a hard coating layer formed on an outermost surface thereof and containing amorphous hard carbon; mixing the sintered product with a carbon precursor, followed by heat treatment to form a soft coating layer on an outer circumferential surface of the sintered product; and forming a carbon nanotube layer on an outer circumferential surface of the soft coating layer.",
