Abstract:
1. A capacitor, comprising: a capacitor stack having at least a first substantially planar electrode having a first metal substrate partially coated in a titanium coating, and at least a second substantially planar electrode having a second metal substrate partially coated in a titanium coating, the first substantially planar electrode having an etched first edge portion with the titanium coating substantially absent, the second substantially planar electrode having an etched second edge portion with the titanium coating substantially absent, the etched first edge portion and the etched second edge portion adapted to electrically connect the first substantially planar electrode to the second substantially planar electrode; a capacitor shell, the capacitor stack disposed in the capacitor shell; and at least one feedthrough connected to the capacitor stack and traversing the material defining the capacitor shell, wherein the etched first edge portion and the etched second edge portion are in alignment defining an electrode connection surface adapted to connect the first substantially planar electrode and the second substantially planar electrode, the first substantially planar electrode and the second substantially planar electrode connected along the electrode connection surface by a conductive interconnect, with electrolyte disposed in the capacitor shell.
