Abstract: A method for forming a high aspect ratio sintered powder anode with low warpage, an anode made thereby and a cathode comprising the anode are provided. The method comprises placing a multiplicity of anode precursors on a forming substrate in a common plane wherein no more than 10% of the anode precursors are out of the common plane. A second substrate is then placed over the forming substrate with the anode precursors between the forming substrate and the second substrate thereby forming a sandwiched assembly. The sandwiched assembly is heated to a sintering temperature of the anode precursors thereby forming the sintered powder anodes. The and sintered powder anodes are removed from between the forming substrate and the second substrate.

Abstract: An improved solid electrolytic capacitor and method of forming a solid electrolytic capacitor is described. The method includes forming an anode comprising a valve metal or conductive oxide of a valve metal wherein an anode lead extension protrudes from the anode. A dielectric is formed on the anode and a cathode layer is formed on the dielectric. The anode, dielectric, and cathode layer are encased in a non-conducting material and the anode lead extension is exposed outside of the encasement at a side surface. A conductive metal layer is adhered to the anode lead extension which allows termination preferably by electrically connecting a preformed solid metal terminal, most preferably an L shaped terminal, to the conductive metal layer at the side surface.
