Jeffrey P. Poltorak - Simpsonville SC, US
Assignee:
Kemet Electonics Corporation - Greenville SC
International Classification:
H01G 9/15
H01G 5/013
US Classification:
29 2503, 29 2542, 29729, 361523, 361525, 264219
Abstract:

Anodes With Corner And Edge Modified Designs

View page
US Patent:
7658986, Feb 9, 2010
Filed:
May 30, 2007
Appl. No.:
11/807765
Inventors:
Jeffrey Poltorak - Fountain Inn SC, US
Yongjian Qiu - Greenville SC, US
Christian Guerrero - Travelers Rest SC, US
Lance Paul Thornton - Simpsonville SC, US
Randy S. Hahn - Simpsonville SC, US
John Prymak - Greer SC, US
Assignee:
Kemet Electronics Corporation - Greenville SC
International Classification:
B32B 3/26
H01G 9/04
US Classification:
428192, 428220, 4283044, 4283191, 4283193, 428209, 428689, 428698, 428702, 361528
Abstract:
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.

Abrasive Process For Modifying Corners, Edges, And Surfaces Of Capacitor Anode Bodies

View page
US Patent:
8057883, Nov 15, 2011
Filed:
Nov 7, 2007
Appl. No.:
11/936265
Inventors:
Jeffrey Poltorak - Fountain Inn SC, US
Christian Guerrero - Travelers Rest SC, US
Yongjian Qui - Greenville SC, US
Lance Thornton - Simpsonville SC, US
Assignee:
Kemet Electronics Corporation - Greenville SC
International Classification:
B32B 3/26
H01G 9/04
US Classification:
428192, 428220, 4283044, 4283191, 4283193, 428457, 428689, 361528
Abstract:
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.

Abstract:
A powder compaction press having opposed rib and channel punches which are interleaved and a production method are used to produce capacitor elements having a uniform compaction density and which are free of surface imperfections.

High Volumetric Efficiency Anodes For Electrolytic Capacitors

View page
US Patent:
8308825, Nov 13, 2012
Filed:
Dec 11, 2009
Appl. No.:
12/636120
Inventors:
Yuri Freeman - Greer SC, US
Philip M. Lessner - Newberry SC, US
Jeffrey Poltorak - Fountain Inn SC, US
Steven C. Hussey - Simpsonville SC, US
Assignee:
Kemet Electronics Corporation - Greenville SC
International Classification:
H01G 9/00
US Classification:
29 2503
Abstract:
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.
