An electrochemical cell includes a can having a first end and a second end and a first element provided within the can and including an electrode. The cell also includes a first terminal integrally formed as a part of the can and extending from one of the first or second ends. The cell further includes a terminal assembly directly coupled to the first element and including a stud configured to act as a second terminal. The first end includes a boss that defines an aperture through which the stud extends, wherein the boss at least partially surrounds the stud and a bushing coupled to the stud.

Case for battery cells

The present invention includes a battery case and battery wherein the battery case includes a housing having a top and a bottom and wherein the housing defines a plurality of cavities that are generally octagonal in cross-section. The battery includes a housing defining octagonal shaped cavities, a terminal coupled to the housing, a top and bottom sealingly coupled to the housing, and a plurality of battery cells disposed win the cavities and electrically interconnected in series with the terminal.

Battery case for thin metal film cells

An injection molded containment for bipolar batteries of the type which include terminal electrodes and one or more bipolar battery cells is disclosed. In the most preferred embodiment of the present invention, a novel spacer is employed, including beveled edges to facilitate sealing of the injection molding material and the individual cells. Furthermore, the preferred spacer includes a crush ridge to assist in sealing. The present invention facilitates assembly of bipolar batteries in a way which improves sealing when compared to other techniques, such as vibration welding.

Injection molded battery containment for bipolar batteries

The preferred embodiment of the present invention relates to a sealed, oxygen recombinant lead-acid battery which includes a series of modules, e.g. 4-volt modules. The modules are prepared from frame and film assemblies which are easily stacked to the desired voltage or capacity. In the preferred embodiment, the assemblies include two 2.0 normal voltage cells, attached in series, three of which are then combined to form a 12-volt system. Modularity eliminates the need for expensive tooling and parts inventory and permits the creation of a wide variety of battery designs. Specially designed vents are employed to permit gas escape during overcharge or if recombination efficiencies are less than desired and to prevent entry of oxygen or moisture when the battery is in its recombinant mode.

Sealed lead acid battery using modular frame construction

An electrode for a lead acid flow through battery, the grids including a plastic frame, a plate suspended from the top of the frame to hang freely in the plastic frame and a paste applied to the plate, the paste being free to allow for expansion in the planar direction of the grid.

Battery electrode growth accommodation

A method of joining thermoplastic frames of a bipolar battery to form a leak-free battery stack. The battery includes a stack of generally rectangular thermoplastic frames, including a series of central frames and a pair of end frames. Each central frame has an opening and a bipolar plate, consisting of a positive electrode and a negative electrode, separated by an electrically conductive substrate, is mounted across the opening. The opposed surfaces of the frame project outwardly beyond the bipolar plate. To join the frames together, a pair of frames is mounted in spaced relation and a pair of back-to-back focused infrared heaters are positioned in the space between the frames and the focal point of each heater is directed into registry with the surface of the respective frame to melt or fuse the surface. The heating unit is then withdrawn and the frames are moved into contact with each other to weld the fused surfaces together.
