NOVELTY - A nonporous carbon having crystallites of a graphite-like carbon and a specific surface area of less than 270 m2/g is made by, preparing an easily graphitizable carbon with multilayer crystallites of graphite; dry distilling carbon at 700-850 degrees Celsius to obtain a calcined carbon; treating calcined carbon with a caustic alkali at 800-900 degrees Celsius; and removing remaining alkali.    USE - For electric-double layer capacitor for electric vehicle.    ADVANTAGE - The inventive method produces a nonporous carbon having crystallites of graphite-like carbon that produces an electric-double layer capacitor with improved performance including capacitance.    DETAILED DESCRIPTION - Production of a nonporous carbon having crystallites of a graphite-like carbon and a specific surface area of less than 270 m2/g, the crystallites having an interplanar spacing d002 of 0.360 to 0.380 nm, the method comprising preparing an easily graphitizable carbon in which multilayer crystallites of graphite have been developed; dry distilling the carbon at 700-850 degrees Celsius to obtain a calcined carbon; treating the calcined carbon with a caustic alkali at 800-900 degrees Celsius; and removing the remaining alkali.    An INDEPENDENT CLAIM is included for a nonporous carbon for use in an electric double-layer capacitor, comprising crystallites of a graphite-like carbon as above having a specific surface area of less than 270 m2/g. The nonporous carbon shows a short relaxation time constant (T2) of 18-50 ms (Gaussian type), a moderate relaxation time component (T2) of 100-400 ms (Lorentzian type), and a long relaxation time component (T2) of 500-2000 ms or longer (Lorentzian type) when 1H resonance is observed at room temperature by pulse nuclear magnetic resonance. The relaxation time components indicate different states of bond of hydrogen atoms left within the carbon structure. The ratio of the sum of the moderate and long relaxation times to the short relaxation time is less than one third.
