Multiple anode capacitor
First Claim
1. A multiple anode high energy density electrolytic capacitor comprising a cylindrical housing containing a body having a layered spiral winding said body having an elongate spiral wound cathode layer sandwiched between elongate spiral wound first and second separator layers, an elongate spiral wound solid core anode layer interleaved in the spiral winding and separated from contacting said cathode layer by being arranged between said first and second separator layers, an elongate spiral wound first porous anode layer interleaved in the spiral winding between said solid core anode layer and a separator layer, wherein said cathode layer, is spiral wound for at least about one turn around the central axis of the spiral winding before interleaving of said solid core anode layer begins, and said solid core anode layer is spiral wound for at least one turn around said central axis of said spiral winding before interleaving of said first porous anode layer begins.
