One embodiment of the present subject matter includes a capacitor, comprising a first metallic cupped shell having a first opening, and a second metallic cupped shell having a second opening, wherein the first opening and the second opening are adapted to sealably mate to form a closed shell defining a volume therein. In the embodiment, the closed shell is adapted for retaining electrolyte. A plurality of capacitor layers in a substantially flat arrangement are disposed within the volume, along with electrolyte, in the present embodiment. The present closed shell includes one or more ports for electrical connections.

A capacitor feedthrough assembly with a cavity including a capacitor stack, including one or more substantially flat anode layers and one or more substantially flat cathode layers in a case with a cover, the case having a first opening sized for passage of the capacitor stack and a second opening defined by a lip. Additionally, the capacitor includes a conductive member attached to the capacitor stack and disposed at least part way through the second opening in the case, and an isolating element disposed between the lip and at least a portion of the connected stack and conductive member. Also, the capacitor includes a curable resin sealingly disposed in the cavity defined by the second opening, the isolating element, and the conductive member, the curable resin electrically isolating the case from the conductive member.

Method and apparatus for providing capacitor feedthrough

One embodiment of the present subject matter includes an apparatus which includes a capacitor stack, including at least one substantially planar capacitor electrode, a case having a first opening and a second opening, the first opening sized for passage of the capacitor stack, the second opening defined by walls having a first thickness, a cover substantially conforming to the first opening and sealingly connected to the first opening and a plate substantially conforming to the second opening, the plate sealingly connected to the second opening, the plate having a second thickness which is approximately greater than the first thickness of the walls defining the second opening, wherein the capacitor stack is disposed in the case.

Method and apparatus for openings in a capacitor case

A capacitor including a capacitor stack. The capacitor includes one or more substantially planar anode layers, and one or more substantially planar cathode layers. The capacitor includes a case with a first opening and a second opening, the first opening sized for passage of the capacitor stack and the second opening defined by walls having a first thickness. Additionally, the capacitor has a cover substantially conforming to the first opening and sealingly connected to the first opening, and a plate substantially conforming to the second opening, the plate adapted for attachment of a terminal, and sealingly connected to the second opening. The plate has a second thickness which is approximately greater than the first thickness of the walls defining the second opening. The capacitor stack is disposed in the case, and the terminal is in electrical connection with the case and at least one capacitor electrode.
