NOVELTY - A carbon particle comprises graphite crystal which has interlayer distance (d(002)) calculated from X-ray diffraction measurement of less than or equal to 3.38 Angstrom . The circularity of particle cross-section of carbon particle is 0.6-0.9. The microcrystal size (Lc(002)) of C axial direction of carbon particle is greater than or equal to 500 Angstrom . The peak intensity ratios (Ih002/Ih110) of surface horizontal to graphite layer as second face (002) of carbon and surface vertical to graphite layer as one hundred tenth (110) face of carbon measured by X-ray diffraction of sample are less than or equal to 600.    USE - A carbon particle for negative electrode used for lithium ion secondary battery (claimed) e.g. paper type battery, button battery, coin-type battery, laminate type battery and cylindrical cell for portable equipment, electric vehicle and electric power storage.    ADVANTAGE - The carbon particle is excellent in high capacity at cycle property.    DETAILED DESCRIPTION - A carbon particle comprises graphite crystal which has interlayer distance (d(002)) calculated from X-ray diffraction measurement of less than or equal to 3.38 Angstrom . The circularity of particle cross-section of carbon particle is 0.6-0.9. The microcrystal size (Lc(002)) of C axial direction of carbon particle is greater than or equal to 500 Angstrom . The peak intensity ratios (Ih002/Ih110) of surface horizontal to graphite layer as second face (002) of carbon and surface vertical to graphite layer as one hundred tenth (110) face of carbon measured by X-ray diffraction of sample are less than or equal to 600. The carbon particle is produced by adding water with respect to water dispersion coating material containing carbon particles (98 mass parts), styrene butadiene resins (1 mass part) and carboxymethylcellulose (1 mass part) so that viscosity may become 1500-2500 mPa.s in 25 degrees C, coating water dispersion coating material on copper foil so that thickness may become 70 mu m, drying at 120 degrees C for 1 hour, and obtaining sample. An INDEPENDENT CLAIM is included for a lithium ion secondary battery.
