Abstract: The present subject matter includes a capacitor stack having a plurality of anode layers, and a plurality of cathodic metal substrates partially coated in a titanium coating. Cathode portions lacking titanium enable weld interconnections which are substantially free of titanium, improving capacitor properties. In some embodiments, anodes are interspersed among cathodes, and are electrically separated from the cathodes, with portions of cathode material attached to the welding area of the anode. These portions of the cathode material are no longer electrically connected to the cathode. As the anode and these cathode portions are welded and aged, leakage current is reduced due to improved oxide growth in the welding area due to the absence of titanium.

Abstract: Implantable defibrillators are implanted into the chests of patients prone to suffering ventricular fibrillation, a potentially fatal heart condition. A critical component in these devices is an aluminum electrolytic capacitor, which stores and delivers life-saving bursts of electric charge to a fibrillating heart. To reduce capacitor size, manufacturers have developed special aluminum foils, such as core-etched and tunnel-etched aluminum foils. Unfortunately, core-etched foils don't work well in multiple-anode capacitors, and tunnel-etched foils are brittle and tend to break when making some common types of capacitors. Accordingly, the inventors devised a new foil structure having perforations and cavities. In an exemplary embodiment, each perforation and cavity has a cross-sectional area, with the perforations having a larger, for example, 2 to 100 times larger, average cross-sectional area than the cavities.
