US Patent:

7578924, Aug 25, 2009
Filed:

Jul 29, 2004
Appl. No.:

10/903958
Inventors:

Xiaofei Jiang - Liberty SC, US
Tearl Stocker - Easley SC, US
R. Jason Hemphill - Pickens SC, US
Thomas F. Strange - Easley SC, US
Assignee:

Pacesetter, Inc. - Sunnyvale CA
International Classification:

C25F 3/02
US Classification:

205674, 205640
Abstract:

Anode foil, preferably aluminum anode foil, is etched using a process of treating the foil in an electrolyte bath composition comprising a sulfate and a halide, such as sodium chloride. The anode foil is etched in the electrolyte bath composition by passing a charge through the bath. The etched anode foil is suitable for use in an electrolytic capacitor.

US Patent:

Filed:

Jul 29, 2011
Appl. No.:

13/194760
Inventors:

David R. Bowen - Taylors SC, US
Ralph Jason Hemphill - Pickens SC, US
Xiaofei Jiang - Clemson SC, US
Corina Geiculescu - Easley SC, US
Tearl Stocker - Easley SC, US
International Classification:

C25F 3/02
US Classification:

205660
Abstract:

Anode foils suitable for use in electrolytic capacitors, including those having multiple anode configurations, have improved strength, reduced brittleness, and increased capacitance compared to conventional anode foils for electrolytic capacitors. Exemplary methods of manufacturing an anode foil suitable for use in an electrolytic capacitor include disposing a resist material in a predetermined pattern on an exposed surface of an anode foil substrate such that a first portion of the exposed surface of the anode foil substrate is covered by the resist material, and a second portion of the exposed surface remains uncovered; polymerizing the resist material; exposing at least the second portion of the exposed surface to one or more etchants so as to form a plurality of tunnels; stripping the polymerized resist material; and widening at least a portion of the plurality of tunnels. The resist material may be deposited, for example, by ink-jet printing, stamping or screen printing.

C23F 3/00
US Classification:

216 6, 216 87, 216 94, 205640
Abstract:

A method of producing a highly etched electrode for a capacitor from a foil is disclosed. The method comprises first applying a laser beam to the foil to form a plurality of marks on the foil surface and then etching the foil. Preferably, the laser marks facilitate etching of foil surface in areas near the marks and retard etching of foil surface inside the marks. After etching, the foil is further processed in a combination of optional steps such as forming and finishing steps. The laser marking of the foil allows for positional control of tunnel initiation, such that tunnel initiation density and the location of tunnel initiation is controlled. By controlling the position of tunnel initiation, foils are etched more uniformly and have optimum tunnel distributions, thus allows for the production of highly etched foils that maintain high strength and have high capacitance. The present invention further includes an electrolytic capacitor comprising etched aluminum anode foils, which have been prepared using the methods of the present invention.
