A capacitor may include a stack assembly. The stack assembly may include a plurality of anode plate members, each having an embedded wire. The anode plate members may be separated by at least one cathode foil sandwiched between separator sheets. A conducting member may electrically connect the embedded wires and may have an externally accessible end portion that is hermetically sealed from the interior of the capacitor. A case covers the stack assembly and may be attached to a cover. The case and cover may enclose the stack assembly within an interior area of the capacitor. The at least one cathode foil may be connected to the case. An electrolyte fluid may be disposed within the interior area of the capacitor. A passage may be provided through a central portion of the stack assembly. A tube, surrounded by insulation, may pass through the passage and may be connected to the cover and the case.

A pellet for use in a capacitor includes a rectangular body formed from compressed and sintered particles of conductive material. The body has an exterior surface which is textured to form a plurality of indentations therein. The profile of the textured surface in cross section is selected from the group including essentially of a curved profile, a sine shape profile, a rectangular shaped profile, a U-shaped profile, and a V-shaped profile.
