  • Patent number: 9088012
    Abstract: By way of example, the present subject matter provides a method, including stacking a plurality of substantially planar electrodes into a stack, in alignment, encapsulating the stack by pressing a first beveled edge of a first cup-shaped housing piece against a second beveled edge of a second cup-shaped housing piece, with the first beveled edge of the first cup-shaped housing piece encouraged into substantially coextensive alignment with the second beveled edge of the second cup-shaped housing piece and joining the first beveled edge of the first cup-shaped housing piece to the second beveled edge of the second cup-shaped housing piece.

  • Patent number: 8867192
    Abstract: An electrolytic capacitor is constructed as a stacked structure of alternating anode and cathode plates. A clip is fitted over a peripheral portion of each cathode plate, the clips being welded together to electrically connect the cathode plates in common. The dimensions of the clips are such that the clips take up approximately the same space away from the edges of the cathode plates as the thickness of the anode plate on each side of a cathode plate when the anode and cathode plates are stacked upon one another.
