NOVELTY - A graphite-type carbon raw material comprises rhombohedral system graphite layer (3H) and hexagonal system graphite layer (2H). Ratio Rate(3R) by X-ray diffraction method of rhombohedral system graphite layer (3R) and hexagonal system graphite layer (2H) is greater than or equal to 31%. USE - A graphite-type carbon raw material used as graphene precursor (claimed). Can also be used for graphene dispersion liquid used in electrode agent of lithium ion battery, electroconductive auxiliary agent, discharge capacity improvement agent, charging-and-discharging-efficiency improvement agent, electrode of capacitor products, electrolyte solution, and electrically conductive agent of electroconductive ink. ADVANTAGE - The graphite-type carbon raw material peels easily in a graphene and can obtain high concentration graphene dispersion easily. DETAILED DESCRIPTION - A graphite-type carbon raw material comprises rhombohedral system graphite layer (3H) and hexagonal system graphite layer (2H). Ratio Rate(3R) defined by equation Rate(3R)=P3/(P3+P4)x 100 (1) by X-ray diffraction method of rhombohedral system graphite layer (3R) and hexagonal system graphite layer (2H) is greater than or equal to 31%, where P3 is peak intensity of (101) plane by X-ray diffraction method of rhombohedral system graphite layer (3R), and P4 is peak intensity of (101) plane by X-ray diffraction method of hexagonal system graphite layer (2H). DESCRIPTION OF DRAWING(S) - The drawing shows an X-ray diffraction profile of the graphite-type carbon raw material. (Drawing includes non-English language text).
