Abstract
A method for producing a composite conductive material having excellent dispersibility is provided. The method includes supporting a catalyst on surfaces of carbon particles; heat treating the catalyst in a helium or hydrogen atmosphere such that the catalyst penetrate the surfaces of the carbon particles and are impregnated beneath the surfaces of the carbon particles at a contact point between the carbon particles and the impregnated catalyst; and heating the carbon particles having the impregnated catalyst disposed therein in the presence of a source gas to grow carbon nanofibers from the impregnated catalyst to form a composite conductive material, wherein the source gas contains a carbon source, and wherein the carbon nanofibers extend from the contact point to above the surfaces of the carbon particles.
