Patent ID: 7324329

Claim:
A method of making an electrochemical-electrolytic capacitor, said method comprising the steps of: (a) preparing an electrochemical capacitor cathode-containing portion, said electrochemical capacitor cathode-containing portion comprising a plurality of electrically-conductive cathode particles in intimate electrical contact with one another and disposed in a first solid ionomer matrix, said first solid ionomer matrix being a proton-conductive, electrically-non-conductive, unitary structure, said first solid ionomer matrix having a volume that extends, on one side, beyond said electrically-conductive cathode particles and is devoid of said electrically-conductive cathode particles; (b) preparing an electrolytic capacitor anode-containing portion, said electrolytic capacitor anode-containing portion comprising a plurality of electrically-conductive anode particles in intimate electrical contact with one another and disposed in a second solid ionomer matrix, said second solid ionomer matrix being a proton-conductive, electrically-non-conductive, unitary structure, said electrically-conductive anode particles differing in composition from said electrically-conductive cathode particles, said second solid ionomer matrix having a volume that extends, on one side, beyond said electrically-conductive anode particles and is devoid of said electrically-conductive anode particles; and (c) then, bringing said electrochemical capacitor cathode-containing portion and said electrolytic capacitor anode-containing portion together so that said volume of said first solid ionomer matrix and said volume of said second ionomer matrix together form a dielectric layer between said electrically-conductive cathode particles and said electrically-conductive anode particles.
