    摘要: The present invention relates to a conductive material manufacturing method and a lithium secondary battery that includes a conductive material manufactured using the same, and the conductive material manufacturing method comprises the step for removing metal impurities in a conductive material by radiating microwaves to the conductive material containing the metal impurities to convert the metal impurities into metal oxides. By converting the metal impurities contained in the conductive material into metal oxides that are inactive at the operating voltage of a battery and are not eluted in an electrolyte solution, the conductive material manufactured by the manufacturing method can enhance the performance characteristic of the battery, particularly, the capacity and lifespan characteristic thereof without concern about the elution of metal impurities and a failure of the battery due to this at a low voltage.
