US Patent:

42185246, Aug 19, 1980

Filed:

Apr 9, 1979

Appl. No.:

6/028468

Inventors:

Bruce S. Dunn - Saratoga Springs NY
Manfred W. Breiter - Schenectady NY
Randall N. King - Johnstown NY

Assignee:

Electric Power Research Institute, Inc. - Palo Alto CA

International Classification:

H01M 436

US Classification:

429104

Abstract:

Novel assembly method and sodium/sulfur battery prepared thereby are provided whereby, in a preformed sulfur compartment, the sulfur electrode is prepared in situ, providing for graduated resistance from the beta-alumina electrolyte to the container wall. The method employs providing for a high resistance conductor as a relatively thin sheet adjacent the beta-alumina electrolyte and a conductive sulfur electrolyte extending from the high resistance conductor to the container wall, whereby the electrolyte is composed of sulfur and small carbon fibers. Conveniently, the high resistance film is positioned adjacent the beta-alumina electrolyte and appropriate amounts of the carbon fiber are introduced into the electrolyte chamber, followed by the addition of molten sulfur.

Filed:

Nov 6, 1978

Appl. No.:

5/958039

Inventors:

Bruce S. Dunn - Schenectady NY
Robert R. Dubin - Ballston Lake NY

Assignee:

General Electric Company - Schenectady NY

International Classification:

B23K 2000

US Classification:

228193

Abstract:

A method is disclosed for forming a composite body which comprises bonding a moderately deformable metallic element to at least a portion of at least one major surface and to an associated portion of the edge surface of a solid ion-conductive electrolyte material element which contains mobile ions of a metal different from the metallic element. A method is disclosed for bonding a composite body to a deformable metallic casing which comprises pressing the sharp edge at the open end of the casing against the composite body while employing an inert atmosphere, elevated temperature and pressure.

Appl. No.:

5/807406

Inventors:

Bruce S. Dunn - Schenectady NY

Assignee:

General Electric Company - Schenectady NY

International Classification:

H01M 202

US Classification:

429 30

Abstract:

A composite body has a substrate with opposite major surfaces, the substrate has a solid ion-conductive electrolyte material region and at least a portion of at least one major surface of a solid ion-insulating material region, and at least one moderately deformable metallic element bonded directly to the ion-insulating material of the substrate, the metal of the metallic element different from the metal of the mobile ions of the solid ion-conductive electrolyte material region.

International Classification:

C25D 500
H01M 618
B32B 904

US Classification:

204 16

Abstract:

A solid electrolyte material composite body is described which comprises an ion-conductive electrolyte portion selected from a specific class and an ion-insulating surface portion of a divalent ion substituted beta-alumina, and both portions having the same mechanical and physical properties. A method of forming such a body and a method of bonding the body to a metallic element are also described.

Inventors:

Bruce S. Dunn - Schenectady NY

Assignee:

General Electric Company - Schenectady NY

International Classification:

H01M 620

US Classification:

429193

Abstract:

A composite body is described which comprises a body of solid ion-conductive electrolyte material, the body having a casing portion with one open end and a header integral with the casing adjacent its open end, and a surface portion of an ion-insulating material on only the exterior surfaces of the header portion of the body. A method of forming such a composite body is also described.

Inventors:

Bruce S. Dunn - Schenectady NY

Assignee:

General Electric Company - Schenectady NY

International Classification:

B23K 2800
C25D 1100

US Classification:

204 16

Abstract:

A method is disclosed for bonding a moderately deformable metallic element to a solid ion-conductive electrolyte material element which contains mobile ions of a metal different from the metallic element. The method includes juxtaposing the elements, and applying an electric potential across the elements to convert a surface portion of the electrolyte material element to an ion-insulating material and to effect bonding between the juxtaposed surfaces.
