摘要

It will provide a composite conducting material which is excellent in conductivity. At least graphite graphene-like, which is detached from the carbon material and the conductive material is a composite conductive material dispersed in the base material, The graphite-based carbon material, rhombohedral graphite layer (3R) and hexagonal graphite layer (2H) and has, the rhombohedral graphite layer (3R) and the hexagonal graphite layer (2H) composite conductive material of the following X-ray diffraction ratio is defined by (Equation 1) Rate (3R) is characterized in that at least 31% of the. Rate (3R) = P3 / (P3 + P4) 100 (Equation 1) Here, P3 is the peak intensity of the (101) plane by X-ray diffraction method of rhombohedral graphite layer (3R) P4 is the peak intensity of the (101) plane by X-ray diffractometry of the hexagonal graphite layers (2H) It is.
