摘要

Provided is a composite conductive material having superior conductivity. The composite conductive material is characterized by having a rhombohedral graphite layer (3R) and a hexagonal graphite layer (2H), the fraction that is Rate (3R) defined by formula 1 according to an X-ray diffraction method of the rhombohedral graphite layer (3R) and hexagonal graphite layer (2H) being at least 31%: Rate (3R) = P3/(P3+P4)×100 …(formula 1). Here, P3 is the peak strength in the (101) plane according to an X-ray diffraction method of the rhombohedral graphite layer (3R), and P4 is the peak strength in the (101) plane according to an X-ray diffraction method of the hexagonal graphite layer (2H).
