Wet electrolytic capacitor for use in a subcutaneous implantable cardioverter-defibrillator

A wet electrolytic capacitor comprising:

• a casing that contains a cylindrical sidewall, wherein the cylindrical sidewall defines an inner surface that surrounds an interior;
• first and second outer anodes positioned within the interior of the casing, wherein the first outer anode has a radiused sidewall and an opposing planar sidewall and the second outer anode has a radiused sidewall and an opposing planar sidewall;
• a central anode positioned within the interior of the casing between the first and second outer anodes, wherein the central anode contains opposing first and second outer sidewalls intersecting with opposing first and second inner sidewalls, wherein the first and second inner sidewalls are planar, wherein the first planar inner sidewall of the central anode faces the planar sidewall of the first outer anode and wherein the second planar inner sidewall of the central anode faces the planar sidewall of the second outer anode;
• at least one cathode positioned within the interior of the casing that contains an electrochemically-active material;
• and
• a working electrolyte that is in electrical contact with the anodes and the electrochemically-active material.
