International Classification:

H01M 1002

US Classification:

429 66, 429 54, 429120, 429159, 429161, 429175

Abstract:

Mechanically and thermally improved rechargeable batteries and modules. The battery is prismatic in shape with an optimized thickness to width to height aspect ratio which provides the battery with balanced optimal properties when compared with prismatic batteries lacking this optimized aspect ratio. The optimized thickness, width and height allow for maximum capacity and power output, while eliminating deleterious side affects. The battery case design allows for unidirectional expansion which is readily compensated for by applying external mechanical compression counter to that direction. In the module, the batteries are bound within a module bundling/compression means under external mechanical compression which is optimized to balance outward pressure due to expansion and provide additional inward compression to reduce the distance between the positive and negative electrodes, thereby increasing overall battery power. Finally the batteries, modules and packs thereof can also include means for providing variable thermal insulation to at least that portion of the rechargeable battery system which is most directly exposed to ambient thermal conditions, so as to maintain the temperature of the rechargeable battery system within the desired operating range thereof under variable ambient conditions.

Abstract:

Mechanically and thermally improved rechargeable batteries, modules and fluid-cooled battery pack systems. The battery is prismatic in shape with an optimized thickness to width to height aspect ratio which provides the battery with balanced optimal properties when compared with prismatic batteries lacking this optimized aspect ratio. The optimized thickness, width and height allow for maximum capacity and power output, while eliminating deleterious side affects. The battery case design allows for unidirectional expansion which is readily compensated for by applying external mechanical compression counter to that direction. In the module, the batteries are bound within a module bundling/compression means under external mechanical compression which is optimized to balance outward pressure due to expansion and provide additional inward compression to reduce the distance between the positive and negative electrodes, thereby increasing overall battery power. The fluid-cooled battery pack includes; 1) a battery-pack case having coolant inlet and outlet; 2) battery modules within the case such that the battery module is spaced from the case walls and from other battery modules to form coolant flow channels along at least one surface of the bundled batteries; and 3) at least one coolant transport means. The width of the coolant flow channels allows for maximum heat transfer.

Ovonic Battery Company, Inc. - Troy MI

International Classification:

H01M 212

US Classification:

429 54

Abstract:

The electrochemical cell of the instant invention includes a case having a gas outlet, one or more positive electrodes positioned within the case, one or more negative electrodes positioned within the case electrode separators positioned between the positive and negative electrodes, electrolyte positioned within the case, and a pressure vent for releasing internal pressure occurring in the case to the surrounding atmosphere. The pressure vent is affixed to the case covering the gas outlet, the pressure vent includes a vent housing having a hollow interior area in gaseous communication with the surrounding atmosphere and the interior of the case via the gas outlet, a pressure release piston positioned within the hollow interior area, the pressure release piston sized to surround the gas outlet and having a seal groove configured to encapsulate all but one surface of a seal mounted within the seal groove, leaving the non-encapsulated surface of the seal exposed, and a compression spring positioned to urge the pressure release piston to compress the seal in the seal groove and block the gas outlet in the case.

International Classification:

H01M 1050

US Classification:

429101

Abstract:

A sealed prismatic metal hydride battery greater than 10 Ah in size comprising a battery case of high thermal conductivity; and at least one bundle of metal hydride electrodes of high thermal conductivity in thermal contact with said battery case. Batteries according to the invention prevent the accumulation of heat that can damage nickel metal hydride batteries particularly during overcharge.

429 54

Abstract:

A sealed battery case comprising: a case of formable metal; a lid for the case, the lid having an annular shroud defining the periphery of at least one opening; at least one terminal having a sealing lip at its circumference; where the terminal is crimp sealed into said annular shroud. Also described is a method of attaching a terminal in a lid opening of a battery case; the opening having an opening and an annular shroud surrounding the opening. The annular shroud is of an inner diameter slightly larger than the diameter of the opening and extending outward from the lid, and the terminal has a diameter smaller than the diameter of the opening and a sealing lip around its circumference. The sealing lip has a diameter in between the diameter of the opening and the diameter of the shroud; the method comprising the steps of: placing a seal of an insulating material; around the sealing lip; inserting the terminal into the shroud; and crimping the shroud around the seal.
