  • Electrode compositions containing carbon nanotubes for solid electrolyte capacitors
    Publication number: 20070242412
    Abstract: An improved capacitor with an anode with an anode wire and an oxide layer on the surface of the anode. A cathode layer is exterior to the oxide layer. A carbon conductive layer is exterior to the cathode layer wherein the cathode layer comprises 5-75 wt % resin and 25-95 wt % conductor. The conductor has carbon nanotubes. An anode lead is in electrical contact with the anode wire and a cathode lead is in electrical contact with the carbon conductive layer.
