Assignee:

Wilson Greatbatch Ltd. - Clarence NY

International Classification:

H01M 610

US Classification:

429 94, 429211, 429241, 607 5

Abstract:

A solid cathode liquid organic electrolyte alkali metal high rate cell wherein a combination of an elongated alkali metal anode and elongated solid cathode with separator therebetween is wound to form an anode-cathode subassembly having a jellyroll type configuration and wherein the combination is shaped so that the resulting sub-assembly has a substantially rectangular cross-section. The anode-cathode sub-assembly is placed in a conductive cell casing of prismatic shape having opposed flat faces, a lead of either the anode or cathode is attached to the cell casing depending upon whether case positive or case negative electrical configuration is desired and a lead of the other of the anode or cathode is connected to an electrical connector means extending through the casing in an insulated manner. The anode and cathode and separator are in face-to-face contact throughout the entire cross-section of the subassembly.

International Classification:

H01M 206

US Classification:

429181

Abstract:

A lithium-iodine cell comprising a casing of electrically conducting material, an anode including a lithium element within the casing, an electrical conductor operatively connected to the lithium element and extending out from the casing, and a cathode comprising iodine-containing material in operative contact with both the casing and the lithium element. The anode electrical conductor is completely sealed from the rest of the cell, and the casing serves as the cathode current collector. The lithium anode element is shaped in a manner increasing the area of the operative surface thereof and enhancing the bond to the anode conductor, and the anode operative surface is provided with a coating of an organic electron donor material. The anode conductor is enclosed within the combination of an insulator element within the casing, an isolator element between the insulator and the conductor, and a ferrule having one end associated with the insulator within the casing and the other end extending from the casing. After assembly, the cathode material is introduced in heated form by means of a filling element through an opening in the lid of the casing which subsequently is closed.

International Classification:

H01M 4300

US Classification:

429185

Abstract:

A lithium-iodine cell comprising a pair of cup-shaped container elements each having a peripheral flange and each containing a lithium anode element and iodine-containing cathode material. The container elements are of material which is heat sealable and which does not exhibit electronic conduction when exposed to iodine. The container elements are juxtaposed with the cathode material of each container being in operative contact with a cathode current collector, and the peripheral flanges of the container elements are heat sealed together. The cell is encapsulated in potting material which is non-reactive with iodine, and the encapsulated cell is contained in an hermetically sealed metal casing having rounded surfaces.
