Publication number: 20100318140Abstract: 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.Type: ApplicationFiled: June 16, 2009Publication date: December 16, 2010Applicant: Medtronic, Inc.Inventors: Michael B.

Patent number: 7837743Abstract: A high voltage capacitor anode for an implantable medical device is fabricated by sintering, anodizing and heat treating a pressed tantalum powder slug. The sintering may be performed at a temperature between approximately 1500° C. and approximately 1600° C. for a time between approximately 3 minutes and approximately 35 minutes; subsequent anodization may be performed by immersing the slug in an electrolyte at a temperature between approximately 15° C. and approximately 30° C. and then applying a voltage across the slug, the voltage being between approximately 175 Volts and approximately 375 Volts; subsequent heat treating may be performed at a temperature between approximately 400° C. and approximately 460° C. for a time between approximately 50 minutes and approximately 65 minutes. Following heat treating, the anode is reformed by a second anodization.Type: GrantFiled: September 24, 2007Date of Patent: November 23, 2010Assignee: Medtronic, Inc.Inventors: Kevin M.
