Abstract
A graphite composite material obtained by mixing graphite materialhaving diversity in the sizes of optical anisotropic structure and optical isotropic structure, the ratio thereof, and crystal direction, and graphite material 2 having a rhombohedron structure, which is different from graphite material 1 and has an average interplanar spacing dof plane (002) of 0.3354 nm to 0.3370 nm measured by the powder X-ray diffraction method and Lc of 100 nm or more. Also disclosed is a carbon material for a battery electrode, a paste for an electrode, an electrode, a battery, a lithium ion secondary battery and a method of producing the graphite composite material.
