▎ 摘  要

NOVELTY - A capacitor comprises a pair of electrodes and an electrolyte. At least one electrode comprises a metal complex (I) or (II), or its adduct, and a carbon material. USE - Capacitor e.g. lithium ion capacitor is used for electric vehicle. ADVANTAGE - The capacitor is relatively economical, and has high capacitance without using a rare metal, such as ruthenium, and can be economically mass-produced without undergoing complicated manufacturing process. DETAILED DESCRIPTION - A capacitor comprises a pair of electrodes and an electrolyte. At least one electrode comprises a metal complex of formula (I) or (II), or its adduct, and a carbon material. M=metal atom;and D -D =nitrogen atom, sulfur atom, or carbon atom. (i) When D1-D28are carbon atoms, each carbon atom may be bonded with H, halo, alkyl, cycloalkyl, alkenyl, alkynyl, aryl, alkylsulfonyl, alkoxy or alkylthio. INDEPENDENT CLAIMS are included for the following: a composite material of metal complex or its adduct, and carbon material, which has a capacitance density of 20 F/cm3 or more; and manufacture of the composite material, which involves (i) dissolving the metal complex or its adduct in a solvent to prepare a solution, (ii) dispersing the carbon material in the solution to prepare a dispersion, and (iii) removing the solvent from the dispersion.
