Abstract: The invention is directed to designs for capacitors of implantable medical devices (IMDs) such as implantable defibrillators, implantable cardioverter-defibrillators, implantable pacemaker-cardioverter-defibrillators, and the like. The capacitor designs can reduce capacitor volume significantly and may also improve charge holding capacity relative to conventional capacitor designs. Moreover, since capacitors typically comprise a significant portion of the volume of an IMD, significant reductions in capacitor volume can likewise significantly reduce the size of the IMD.

Abstract: The present teachings provide methods of preparing an anode for use in a high volumetric energy density electrolytic capacitor. A lead wire is de-oxidized and sintered in a valve metal powder compact to form the anode. The de-oxidizing and sintering are conducted in the presence of a reactive metal having a stronger affinity for oxygen than the valve metal powder. A residual reactive metal and at least one reactive metal reaction product are removed from the anode surface with a leaching process. Remaining residual reactive metal and reactive metal reaction products are redistributed by thermal processing. A capacitor containing the anode has an operating voltage greater than 90% of the forming voltage.

Following heat treating, the anode is reformed by a second anodization.
