Electrochemical Cell With Electrode Hold-Down
US Patent:
4276361, Jun 30, 1981
Filed:
Jun 26, 1980
Appl. No.:
6/163242
Inventors:
Robert J. Boudrot - Falmouth MA

Assignee:
GTE Products Corporation - Stamford CT
International Classification:
H01M 210
US Classification:
429186
Abstract:
A primary electrochemical cell including a hold-down unit for securing and preventing movement of a physically large battery stack of the cell. The battery stack is disposed within a rectangular metal housing of the cell, together with an electrolytic solution, and comprises a large number of rectangular anodes and cathode structures arranged in the battery stack in alternation.
The hold-down unit is disposed in the cell in abutment with the top of the battery stack and an inner surface of a cover assembly secured to the housing. The hold-down unit includes a pair of opposed end sections in abutment with the interior surfaces of one pair of walls of the housing and lying orthogonally to the planes of the components of the battery stack, and a pair of opposed connecting sections in abutment with the interior surfaces of the other pair of walls of the housing and interconnecting the pair of end sections. The connecting sections are spaced from the battery stack and define, together with the end sections, top and side openings. These openings, together with large openings in the end sections, minimize the displacement of electrolytic solution in the region of the cell above the battery stack.

Abstract:
A modular lithium battery having a plurality of cells, having electrical connecting means connecting the cells to output terminals, and venting means for releasing discharge byproducts to a chemical scrubber. Stainless steel cell casings are potted in an aluminum modular case with syntactic foam and epoxy. The wall thickness resulting is about 0. 5 inches.
