NOVELTY - Graphite particles have bulk density of 800-1000 kg/m3 and specific surface area of 3000-6000 m2/kg. The viscosity of graphite paste formed by blending graphite particles with polyvinylidene chloride and 1-methyl-2-pyrrolidone, is 2 Pa.second or less at a shear rate of 4 second-1 and 25degreesC. The graphite paste contains 55 wt.% of 1-methyl-2-pyrrolidone, and 45 wt.% of sum of graphite particles and polyvinylidene chloride.    USE - For cathodes of non-aqueous electrolyte secondary battery (both claimed) used in portable electronic devices, electric vehicles and electric power storage devices.    ADVANTAGE - The graphite particles exhibit excellent adhesion and improved coating property. The electrode made of the graphite particles has rapid charging and discharging property and overcharge property. The battery formed using the electrode made of the graphite particles has high capacity and excellent cycle property.    DETAILED DESCRIPTION - Graphite particles have bulk density of 800-1000 kg/m3 and specific surface area of 3000-6000 m2/kg. The viscosity of graphite paste formed by blending graphite particles with polyvinylidene chloride and 1-methyl-2-pyrrolidone, is 2 Pa.second or less at a shear rate of 4 second-1 and 25degreesC. The graphite paste contains 55 wt.% of 1-methyl-2-pyrrolidone, and 45 wt.% of sum of graphite particles and polyvinylidene chloride. The amount of polyvinylidene chloride is 10 wt.% of total weight of graphite particles and polyvinylidene chloride.    INDEPENDENT CLAIMS are included for the following:    (1) manufacture of graphite particles which involves heat processing graphite particles having average particle diameter of 10-50 mum and true density of 2200 kg/m3 or more at 300-1300degreesC so that weight reduction percentage of graphite particles becomes 30% or less. After heat processing, mechanical surface reforming is carried out to form graphite particles;    (2) cathode for non-aqueous electrolyte secondary battery which is obtained by adhering above graphite particles on the surface of collector; and    (3) non-aqueous electrolyte secondary battery.
