Mechanical hermetic seal

A housing for an energy storage cell includes an interior which provides beneficial properties to fabricators of the cell. The cell may be hermetically sealed by conventional laser welding techniques.

Aluminum housing with a hermetic seal

This disclosure relates to a method for making a lithium anode for an electrochemical cell and more particularly to a method of extruding a ribbon of lithium into a reaction chamber for reacting the surface of the extruded lithium metal with nitrogen to produce a coating of lithium nitride on the surface of the lithium metal ribbon.

Method for making a lithium anode for an electrochemical cell

A strip of electrode material is extended across a through-hole in a supporting surface and pushed through the hole into a container of an electrochemical cell. The strip assumes a generally U-shaped appearance as it is pushed through the hole by a mandril. The mandril preferably includes an elastomeric head which expands radially outward upon pressing contact with the interior base wall of the container so as to press the trailing legs of the U-shaped material outward against the interior container wall.

Method and apparatus for inserting electrodes into the container of an

In accordance with the invention, a novel electrochemical cell and a method for making same is provided which is particularly suitable for use in a battery of the type employing one or more cells. One feature of the cell includes a sealed non-metallic pouch of thin flexible material which forms a cell adaptable to varying battery configurations as well as cell shapes. A second feature of the cell includes a novel feedthrough arrangement wherein a pair of electrically conductive members are located on respective sides of an interjacent through-hole formed in the housing material. The pair of electrically conductive members are coupled through the through-hole to form the feedthrough. An electrode of anode material is electrically coupled to the internally located member of one feedthrough pair. An electrode of cathode material is electrically coupled to the internally located member of the other feedthrough. The cell further includes electrically insulative porous material for separating the electrodes, as well as a volume of electrolyte electrochemically coupling the electrodes.

Electrochemical cell

An improved preformed cathode is described for use in a primary electrochemical cell. The novel cathode of the present invention is a self-supporting member having a configuration which is determined by the spatial limitations of the particular primary electrochemical cell in which the cathode is to be utilized. The cathode is formed from about 65 to 94 weight percent of carbon black, at least 1 weight percent of a mechanical binder which is inert in the primary electrochemical cell, 1 to 10 weight percent of a fibrous material such as carbon, glass, ceramic fluoropolymer, and/or metallic fibers, and any remainder thereof is graphite powder. The preformed cathode is formed by mixing the individual components together with a quantity of a suitable liquid to form a uniform mixture which is sheeted to a self-supporting structure of the desired thickness. Thereafter, the preformed cathode is dried, cured for a period of time sufficient to remove substantially all of the liquid and to stabilize the mechanical binder, and cut into discs for assembly into cells.

Fiber reinforced cathode for electrochemical cell

A lithium/thionyl chloride electrochemical cell, particularly suitable for use in surgically implanted devices, is disclosed which exhibits a step change in its output voltage sufficiently prior to full cell discharge to enable the timely replacement of the cell under non-critical circumstances.

Step cell

A 'ball and socket' seal arrangement for an electrochemical cell is disclosed wherein a ball of insulating material is captively retained in a socket formed by a portion of the cell cover in cooperation with a retaining member. The cell feedthrough passes through the socket and the insulating ball. After assembly of the components, the sockets are compressed, thereby forcing the insulator ball to conform to the inner surface of the socket to make an effective seal.
