▎ 摘  要

NOVELTY - A graphite-based carbon material comprises a rhombohedral graphite layer and a hexagonal graphite layer. The rate (3R) of rhombohedral graphite layer and hexagonal graphite layer is 31% or more calculated based on peak intensity of (101) plane of the rhombohedral graphite layer based on X-ray diffraction method, and peak intensity of (101) plane of the hexagonal graphite layer based on X-ray diffraction method. USE - Graphite-based carbon material is used as graphene precursor for preparing graphene dispersion for lithium-ion battery. ADVANTAGE - The graphite-based carbon material has excellent handleability, and is prepared by simple process with high productivity. The graphene is easily exfoliated when the graphite-based carbon material is used as precursor. The graphite-based carbon material enables easy preparation of highly-concentrated graphene dispersion. DETAILED DESCRIPTION - A graphite-based carbon material comprises a rhombohedral graphite layer and a hexagonal graphite layer. The rate (3R) of rhombohedral graphite layer and hexagonal graphite layer is 31% or more calculated by relation: rate (3R)=P3/(P3+P4)x 100 based on X-ray diffraction method, where P3 is peak intensity of (101) plane of the rhombohedral graphite layer based on X-ray diffraction method, and P4 is peak intensity of (101) plane of the hexagonal graphite layer based on X-ray diffraction method. An INDEPENDENT CLAIM is included for production of graphite-based carbon material, which involves carrying out radiowave force-based treatment and physical force-based treatment to natural graphite material in vacuum or in the air.
