First Claim
1. An apparatus, comprising:
- a capacitor case sealed to retain electrolyte;
a first electrode disposed in the capacitor case, the first electrode comprising a substrate with a sintered portion on a side of the substrate, the sintered portion bordering a connection portion on the side of the substrate, the connection portion substantially free of sintering;
a connection post including a slot and connected to the substrate at the connection portion, wherein the connection portion is disposed at least partially in the slot of the connection post wherein the connection post includes a base defining the slot and an elongate post extending from the base;
a first electrode terminal disposed on an exterior of the capacitor case in electrical communication with the connection post and the first electrode;
a second electrode disposed in the capacitor case;
a separator disposed between the second electrode and a first electrode; and
a second electrode terminal disposed on an exterior of the capacitor case and in electrical communication with the second electrode, with the first electrode terminal and the second electrode terminal electrically isolated from one another.
