Improved method for producing an aluminum slug anode from multi layer aluminum foils and an aluminum slug anode produced from multi layer aluminum foils.
Etched aluminum foils are stacked to a multi layer stack and then hot pressed to the final thickness of the desired aluminum slug anode. Following the hot pressing, the hot pressed multi layer stack of aluminum foils is sintered, preferably but not necessarily in a reducing atmosphere. This production process utilizing hot pressed aluminum foils is easier to handle than the process with pressed aluminum powder. If the sintered and hot pressed multi layer stacks do not have the desired shape, they can be cut after sintering, but also at earlier or later stages of the whole process. In a next step the slug anode is provided with means for electrically contacting the slug anode. In a last step the aluminum slug anode is anodized. Further, an implantable medical device comprising capacitors with the slug anode is produced. The implantable medical device is a cardioverter and/or defibrillator. |
