发明名称 Polarizable Electrode Member, Process for Producing the Same, and Electrochemical Capacitor Utilizing the Member
摘要 A polarized electrode for use in an electrochemical capacitor, in which electrode includes a current collector made of a metal plain foil, an anchor coat layer formed at least on one of the surfaces of the current collector, and an electrode layer formed on either the anchor coat layer or the current collector. The anchor coat layer contains a conductive carbon and a binder. The conductive carbon is graphitized carbon black. The binder contains at least one selected from the group consisting of an ammonium salt of carboxymethylcellulose, a rubber polymer, polytetrafluoroethylene, polyvinyl alcohol, polyvinyl pyrrolidone, alternating copolymer of isobutylene-maleic anhydride. With this configuration, a polarized electrode can be made thinner, and an electrode layer can be formed directly on the anchor coat layer. Furthermore, it can ensure sufficient coupling strength between the current collector and the electrode layer, and increase the energy density and the power density realizing a reduced resistance.
