CARBON MATERIAL FOR HYBRID CAPACITOR, ELECTRODE FOR HYBRID CAPACITOR USING CARBON MATERIAL, AND HYBRID CAPACITOR

摘要

PPROBLEM TO BE SOLVED: To provide a carbon material for a hybrid capacitor capable of improving a high-speed charging/discharging characteristic, to provide an electrode for the hybrid capacitor using the carbon material, and to provide the hybrid capacitor for improving the high-speed charging/discharging characteristic. PSOLUTION: The carbon material for the hybrid capacitor is provided with a carbon particle in which the inter-layer spacing of a carbon 002 plane found out by XRD measurement is 3.40 to 3.70 and a carbon layer formed on the surface of the carbon particle; wherein the ratio (weight ratio) of the carbon layer to the carbon particle is 0.001 to 0.05 and a specific surface area found out by carbon dioxide adsorption in 273K is 0.1-5 mSP2/SP/g or more and 5 mSP2/SP/g or less.
