Abstract:
1. A capacitor, comprising: a first metallic cupped shell defining a first opening; a second metallic cupped shell defining a second opening which conforms to the first opening defined by the first cupped shell, with the first and second cupped shells sealed together with a laser weld, the first and second cupped shell defining a volume; a first element disposed in the volume, the first element including a first anode layer stacked onto and touching a second anode layer, and further including a first substantially planar cathode stacked with the first and second anode layers, and a first separator between the second anode layer and the first substantially planar cathode; a third anode layer disposed in the volume and stacked into a stack with the first element, the stack having an exterior profile, with the first, second, and third anode layers being interconnected as an anode of the capacitor; and electrolyte substantially filling the volume and touching the first element and the third anode layer, wherein the volume defined by the first and second cupped shells is adapted to conform to the exterior profile of the stack.
