PURPOSE: Provided is a process for producing carbon material used for anode material of a lithium ion secondary battery by mixing a graphite with a carbon, the produced carbon material can improve the properties of the lithium battery. CONSTITUTION: The process for producing the carbon material comprises the steps of: dissolving a carbon material in an organic solvent, such as acetone, pyridine, tetrahydrofuran, toluene, benzene, quinoline, to prepare a mixture solution; coating graphite powder with the mixture solution, wherein the graphite powder has a particle size of 1-30 micrometer; drying and then carbonizing it at a temperature of 500-2000deg.C under the inert atmosphere. |
