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.
