Abstract:
1. An apparatus, comprising: a capacitor case sealed to retain electrolyte, the capacitor case inner surface defining a conductive substrate; a first electrode comprising a plurality of first electrode material portions disposed in the capacitor case, the plurality of first electrode material portions comprising a sintered portion disposed on a second substrate, wherein the plurality of first electrode material portions are disposed onto the second substrate, in a nested configuration, with at least a first first electrode portion having a different area than a second first electrode portion; a conductor coupled to the second substrate in electrical communication with the sintered portion, the conductor seatingly extending through the capacitor case to a terminal disposed on an exterior of the capacitor case with the terminal in electrical communication with the sintered portion; a second electrode disposed in the capacitor case, the second electrode comprising a sintered portion disposed on the conductive substrate on the inner surface of the capacitor case; a separator disposed between the first electrode and the second electrode; 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.
