A rechargeable battery and a method of fabricating which includes stacking a plurality of electrode pages having an uncoated portion between portions coated with an active electrode material. The electrode pages are arranged in a stack and an overall current collector is connected at the uncoated portion in order to form an electrode booklet. The overall current collector maintains the arrangement of the electrode pages and electrically connects all of the uncoated portions of the electrode pages. A tilted stack of electrode pages is utilized when a large number of electrodes are desired to result in a battery cell having a vertical orientation.
Current Collecting Post Seal For High Durability Lithium-Ion Cells

International Classification:
H01M 2/08 B29C 65/00
US Classification:
429175, 429163, 429164, 429178, 429179, 1563082
Abstract:
A cover assembly for a Lithium-ion battery container to improve the durability of the battery. A high pressure injection molded polymer is combined with flanges disposed on the current collecting posts of the battery to provide an improved seal for the battery cover, especially at the interface of the cover and the current collecting posts. The injection molded polymer is fused to the flanges, current collecting posts and container cover to result in a diffusion path of increased length for gases and/or liquids which are known to enter or escape from battery containers. Additional polymer layers can be applied to the assembly to further improve the seal.

International Classification:
H01M 436 H01M 614
US Classification:
429105
Abstract:
A non-aqueous electrochemical cell having a solid active cathode, an active metal anode and a low vapor pressure highly conductive electrolyte comprising a liquid solvate-complex of sulfur dioxide (SO. sub. 2) and an alkali or alkaline earth metal salt soluble therein such as those having a Group 3A element halide anion with the ratio of salt to SO. sub. 2 in said electrolyte ranging from about 1:1 to 1:7.

Assignee:
Duracell Inc. - Bethel CT
International Classification:
H01M 614
US Classification:
429101
Abstract:
A novel inorganic non-aqueous electrochemical cell having an alkali or alkaline earth metal anode, an inorganic electrolyte comprised of an SO. sub. 2 solvent with an alkali or alkaline earth metal halide salt of aluminum, tantalum niobium or antimony, dissolved in the SO. sub. 2 and a cathode comprised of a carbonaceous material having an apparent bulk density in excess of 5 lb/ft. sup. 3 (80 gm/l). Lower bulk density carbonaceous material may, however, be used in electrolytes having high salt concentrations. Ketjenblack EC (furnace black) carbonaceous material may be admixed with a solid cathode active material which is substantially insoluble in the SO. sub. 2 electrolyte to provide a high primary cell capacity and an effectively rechargeable cell. There is no SO. sub. 2 per se discharge in the cell.
