摘要： Methods of preparing an electrode are provided. A metal powder can be sintered onto a portion of a lead wire to form a connection region. An additional metal powder can be de-oxidation sintered onto the connection region to form the electrode. The oxides formed during the de-oxidation sintering are then removed from the electrode.

摘要： Implantable medical devices (IMDs) and components, including flat electrolytic capacitors and methods of making and using same, particularly an improved electrolytic capacitor fabricated of an electrode stack assembly comprising a plurality of capacitor layers stacked in registration upon one another. Each capacitor layer comprises a valve metal cathode layer having a cathode tab, a valve metal anode layer having an anode tab, and a separator layer located between the cathode layers. The anode layer is assembled from a plurality of valve metal anode sheets that are etched and anodized, stacked side-by-side, and electrically and mechanically joined together by laser weld beads. A valve metal anode tab having a thickness equal to one or more anode sheet is inserted into a tab notch in one or more stacked anode sheet and joined to the anode sheet stack by laser welding the tab and sheet edges together.

摘要： Methods of preparing an electrode are provided. A metal lead wire is pre-treated to facilitate bonding of the lead wire to a metal powder during subsequent de-oxidation sintering. A connection region can be formed by directly contacting the metal lead wire with a liquid reactive metal. After removal of resultant oxides, an additional metal powder can be de-oxidation sintered onto the connection region to form the electrode. The oxides formed during the de-oxidation sintering are then removed from the electrode.

摘要： 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.
