Abstract
One embodiment of the present subject matter includes a capacitor, comprising a first cupped shell having a first opening, and a second 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.
Claims20
A method, comprising:
- positioning a plurality of substantially planar capacitor layers in a stacked arrangement in a first cupped shell having a first opening;
- sealably mating a second opening of a second cupped shell to the first opening of the first cupped shell along a joint, the mated first and second cupped shells defining a closed shell having a volume and at least one electrical port providing access to the volume;
- and
- disposing electrolyte in the volume.
A method, comprising:
- stacking into a first element a first anode layer which abuts a second anode layer;
- fixing in alignment the first element, a first separator and a first substantially planar cathode layer, with the first separator isolating the first anode layer and the first substantially planar cathode;
- stacking into a stack the first element and a third anode layer, with a second separator isolating the first element and the third anode layer;
- interconnecting the first, second and third anode layers;
- retaining the stack in a volume defined by a first cupped shell which is mated to a second cupped shell such that the first and second cupped shells conform to the stack, with electrolyte substantially filling interstices in the volume;
- and
- sealing the first element into the volume with a seal.
