Claim Text:
1. An apparatus, comprising: a capacitor case sealed to retain electrolyte; a first electrode disposed in the capacitor case; a conductor coupled to the first electrode in electrical communication with the conductor, the conductor sealingly extending through the capacitor case to a terminal disposed on an exterior of the capacitor case, with the terminal in electrical communication with the first electrode; a second electrode disposed in the capacitor case in a stack with the first electrode and adjacent the first electrode, the second electrode having a second electrode thickness; a first separator disposed between the first electrode and the second electrode and having a first separator thickness; a third electrode disposed in the capacitor in the stack with the first electrode and the second electrode and adjacent the second electrode, the third electrode in electrical communication with the first electrode and including a first sintered portion of a first thickness, and a second portion of a second thickness larger than the first thickness; a second separator disposed between the third electrode and the second electrode and having a second separator thickness; and a second terminal disposed on the exterior of the capacitor case and in electrical communication with the second electrode, with the terminal and the second terminal electrically isolated from one another, wherein the second thickness of the third electrode is substantially equivalent to a total thickness of the first thickness of the third electrode plus the second electrode thickness plus the first separator thickness plus the second separator thickness.
