Filed:

Sep 26, 2000

Appl. No.:

09/669370

Inventors:

Joseph Probst - Williamsville NY
Esther S. Takeuchi - East Amherst NY
Sally Ann Smesko - North Tonawanda NY

Assignee:

Wilson Greatbatch Ltd. - Clarence NY

International Classification:

H01M 458

US Classification:

4292317, 4292318, 42923195, 429245, 296231

Abstract:

An alkali metal/solid cathode electrochemical cell, particularly a Li/CF cell, having an electrolyte-to-cathode (E/C) weight ratio of about 0. 938 to about 0. 73, and an anode-to-cathode (A/C) capacity ratio of about 1. 03, is described. This provides the cell with an improvement in terms of delivered capacity of about 6% to about 15% under a 1 kohm discharge load, and of about 2% to about 5% under a 2 kohm load in comparison to prior art Li/CF cells. Fabricating the cathode electrode at such high pressures was not previously thought possible.

Assignee:

Wilson Greatbatch Ltd. - Clarence NY

International Classification:

H01M 464

US Classification:

429233, 429241, 429242, 296231, 29 2

Abstract:

The basket weave structures has a lattice construction surrounded by a frame and comprising first strand structures intersecting second strand structures to provide a plurality of diamond-shaped openings or interstices bordered by the strands. The strand structures intersect or join with each other at junctions thereby forming the current collector as an integral unit.

International Classification:

H01M 204

US Classification:

429175, 429101, 429199, 429177

Abstract:

A header insulator for an electrochemical cell is described. The header insulator provides a boss for the terminal ferrule, a boss for the fill ferrule, and at least one boss disposed along the length of the insulator to provide for alignment of the electrode assembly inside the case.

Appl. No.:

10/074369

Inventors:

Joseph M. Probst - Williamsville NY, US

Assignee:

wilson Greatbatch Ltd. - Clarence NY

International Classification:

H01M004/72

US Classification:

429233, 429237, 429238, 429241, 429244, 29 2, 296231

Abstract:

The present invention relates to a current collector for an electrochemical cell. The current collector has a unique grid structure comprised of a frame supporting a plurality of radial strands as conductors radiating outwardly from a focal point on a connector tab. The frame and radial conductors are maintained in a fan-like orientation with respect to each other by two groups of concentric conductor strands, one located adjacent to the tab, the other spaced a substantial distance therefrom. The radiating conductors provide a more direct path to the connector tab for electron flow. This results in the current collector having reduced internal resistance in comparison to conventional current collector designs.

International Classification:

H01M006/12

US Classification:

429162, 429151, 429161, 429163

Abstract:

An economical method for manufacturing an electrode assembly of virtually any shape to fit into a similarly shaped casing without compromising volumetric efficiency is described. This is accomplished by providing an electrode assembly of multiplate anode and cathode plates that substantially match the internal shape of the casing. That way, no matter what shape the device being powered by the cell dictates the electrode assembly assumes, as little internal volume as possible is left unoccupied by electrode active materials.
