Abstract:
A graphite carbon composite material including a graphite material having diversity in the sizes of optical anisotropic structure and optical isotropic structure, the ratio thereof, and crystal direction, and a carbon material on the way to a graphitized structure of easily-graphitizable carbon. Also disclosed is a carbon material for a battery electrode, a past for an electrode, an electrode, a battery, a lithium ion secondary battery and a method of producing the graphite carbon composite material.
