1. An apparatus, comprising:
a capacitor case sealed to retain electrolyte;
a sintered cathode disposed in the capacitor case, the sintered cathode having a serpentine shape in a cross-section of the sintered cathode defining peaks in the cross-section of the sintered cathode on both a first side and a second side of the sintered cathode;
a sintered anode disposed in the capacitor case, the sintered anode having a shape in a cross-section of the sintered anode including a plurality of voids shaped and positioned to receive the peaks on the first side of the sintered cathode, wherein one or more of the peaks on the first side of the sintered cathode are positioned within the voids such that a tip surface of each of the one or more peaks on the first side of the sintered cathode is nestled within and abutting a back surface of a respective void of the plurality of voids;
a conductor coupled to the sintered anode, the conductor sealingly extending through the capacitor case to a terminal disposed on an exterior of the capacitor case;
a separator between the sintered anode and the sintered cathode; and
a second terminal disposed on the exterior of the capacitor case and in electrical communication with the sintered cathode, with the terminal and the second terminal electrically isolated from one another.
