Abstract:
The present invention provides an anode material for a lithium-ion battery comprising a carbon particle having a particle size of 5 μm to 30 μm, and including defective portions on a surface of the carbon particle, the defective portions being grooves formed by cathodically exfoliating graphene layers from the carbon particle.
