20080299335 | ABRASIVE PROCESS FOR MODIFYING CORNERS, EDGES, AND SURFACES OF CAPACITOR ANODE BODIES - Porous sintered bodies for capacitors formed from valve metals are treated by electrolysis to form a dielectric layer and coated with cathode layers. When standard parallelepiped shapes are used as they were passed, cathode coverage at the sharp corners and edges is non-uniform and failures occur at those locations. Treating pressed anode bodies with an abrasive process alters the sharpness of corners and edges, creating rounded transitions between primary surfaces and remove surface imperfections resultant from the pressing process both of which enhance cathode layer uniformity. | 12-04-2008 |
20080299371 | Anodes with corner and edge modified designs - Porous sintered anode bodies for capacitors formed from valve metals are treated by electrolysis to form a dielectric layer and coated with cathode layers. When standard parallelpiped shapes are used, cathode coverage at the edges and corners is non-uniform and failures occur at those locations. Rectangular prisms, obround prisms and cylindrical prisms are formed with transition surfaces at edges and corners, such as chamfers and curves, to enhance cathode layer uniformity. The transition surface greatly enhances the application of polymer slurries. | 12-04-2008 |
20090279233 | HIGH VOLUMETRIC EFFICIENCY ANODES FOR ELECTROLYTIC CAPACITORS - A method for treating anodes of refractory valve metals by deoxidizing the anodes using Mg in an oven, prior to sintering. The process limits free oxygen in the metal compact and improves performance of a capacitor, especially with regards to rated voltage. | 11-12-2009 |

20110149477 | SOLID ELECTROLYTIC CAPACITOR AND METHOD OF MANUFACTURE - 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. | 06-23-2011 |
