Abstract
A capacitor includes a cathode having a coating including an oxide of one of cobalt, molybdenum, and tungsten, a nitride of a metal selected from the group consisting of titanium, vanadium, zirconium, niobium, molybdenum, and tungsten, a carbide of a metal selected from the group consisting of vanadium, niobium, molybdenum, and tungsten, an intercalation carbon cathode, or an electrically conducting polymer selected from polyacetylene, polypyrrole, poly-p-phenylene, polythiophene, poly-3-phenylthiophene, and poly-3-(4-fluorophenyl)-thiophene, an anode including a metal selected from tantalum, aluminum, niobium, zirconium, and titanium, spaced from the coating, and an electrolyte in contact with the coating and the anode.
Claims4
A capacitor comprising:
- a cathode comprising a coating including a nitride of a metal selected from the group consisting of titanium, vanadium, zirconium, niobium, molybdenum, and tungsten;
- an anode spaced from the coating and including a metal selected from the group consisting of tantalum, aluminum, niobium, zirconium, and titanium;
- and
- an electrolyte disposed between and in contact with the coating and the anode.
A capacitor cell comprising:
- a first metal body;
- a cathode comprising a coating including a nitride of a metal selected from the group consisting of titanium, vanadium, zirconium, niobium, molybdenum, and tungsten;
- a second metal body spaced from the coating;
- an anode including a metal selected from the group consisting of tantalum, aluminum, niobium, zirconium, and titanium disposed on the second metal body opposite the first metal body;
- and
- an electrolyte disposed between and in contact with the coating and the anode.
