  • Electrode for electrochemical capacitor and electrochemical capacitor using same
    Patent number: 8988858
    Abstract: A negative electrode for an electrochemical capacitor includes a current collector having electric conductivity, and an electrode layer formed on a surface of the current collector and having cations stored therein. In at least a part of the electrode layer, a value of ratio Ia/Ib of peak value Ia indicating a presence of an anion decomposition compound and peak value Ib indicating a presence of an electrolyte in a spectrum of an atom forming the anion is 0.45 or more and less than 2.55 as measured using X-ray photoelectron spectroscopy.
    Type: Grant
    Filed: October 14, 2011
    Date of Patent: March 24, 2015
    Assignee: Panasonic Intellectual Property Management Co., Ltd.
    Inventors: Kiyohiro Isii, Hideki Shimamoto, Junko Fujisawa, Susumu Nomoto
