A graphite-based carbon material is disclosed which is suitable as a graphene precursor, from which a highly-concentrated graphene dispersion can easily be obtained. The graphite-based carbon material has rhombohedral graphite layer and a hexagonal graphite layer wherein a Rate, which is defined by Equation 1, is 31% or more: Rate = P3/ (P3+P4) x100 Equation 1 wherein P3 is a peak intensity of a (101) plane of the rhombohedral graphite layer based on the X-ray diffraction method, and P4 is a peak intensity of a (101) plane of the hexagonal graphite layer based on the X-ray diffraction method. The graphite-based carbon material can be produced by carrying out radiowave and physical treatment on a natural graphite material. |
