Abstract
An aluminum slug anode usable in capacitors is produced from multiple-stacked layers of aluminum foils. The foils are stacked (possibly after cutting them to have an area similar to the area desired for the anode), hot-pressed, sintered, and anodized to generate the anode. A contact in electrical communication with the foils is formed, as by welding a contact across at least some of the foils. A capacitor casing be formed by situating the anode within a casing which serves as a cathode, with the anode being wrapped in a dielectric such as separator paper.
Claims30
A method of producing an aluminum slug anode for a capacitor, the method including the steps of:
- a. stacking etched aluminum foils into a multi-layer stack,
- b. hot pressing the multi-layer stack of aluminum foils,
- c. sintering the pressed multi-layer stack of aluminum foils, and
- d. anodizing the multi-layer stack of joined aluminum foils.
