20080292958 | INSULATIVE FEEDTHROUGH ASSEMBLY FOR ELECTROCHEMICAL DEVICES - An insulative feedthrough receives an electrical lead therethrough and includes a ferrule having first and second open ends and an interior surface. At least one polymeric guide member is positioned substantially within the first end of the ferrule and has an aperture therethrough for receiving the lead. An insulating material is deposited in the ferrule through the second end for sealingly engaging the lead and the interior surface of the ferrule. | 11-27-2008 |
20090269663 | ALKALINE BATTERY - An alkaline battery of the present invention includes a battery case, a power generating element housed in the interior of the battery case, and an assembled sealing part for closing the opening of the battery case. The assembled sealing part includes a resin sealing member. The sealing member includes a central cylindrical portion having a through-hole for inserting a shank of a negative electrode current collector therethrough, a peripheral cylindrical portion interposed between the periphery of the negative electrode terminal plate and the end portion of the opening of the battery case, and a joint portion for joining the central cylindrical portion and the peripheral cylindrical portion. The end portion of the opening of the battery case is curved such that the top of the peripheral cylindrical portion of the sealing member is wrapped therein, and the curved portion is crimped inward so that the periphery of the negative electrode terminal plate is fixed tightly. The sealing member includes polyamide having an equilibrium moisture content at a relative humidity of 50% of 0.9 to 1.7%. | 10-29-2009 |
20100291435 | BATTERY PARTS HAVING RETAINING AND SEALING FEATURES AND ASSOCIATED METHODS OF MANUFACTURE AND USE - Battery parts having retaining and sealing features and associated assemblies and methods are disclosed herein. In one embodiment, a battery part includes a base portion that is configured to be embedded in battery container material of a corresponding battery container. The battery part and base portion include several torque resisting features and gripping features that resist torsional or twist loads that are applied to the battery part after it has been joined to the battery container. For example, the base portion can include several internal and external torque resisting features and gripping features that are configured to resist twisting or loosening of the battery part with reference to the battery container material, as well as prevent or inhibit fluid leakage from the battery container. | 11-18-2010 |
20110129726 | ELECTROCHEMICAL DEVICE AND MANUFACTURING METHOD THEREOF - An electrochemical device according to the present invention has an outer package including a metal film; a battery element enclosed in the outer package; resin layers provided at least inside a sealing region of the outer package; and a lead extending from the battery element through between the resin layers in the sealing region of the outer package to the outside of the outer package, and a shape of the lead in the sealing region includes front and back surfaces both consisting of curved surfaces. In the sealing region, a maximum thickness Z | 06-02-2011 |
20120270100 | Secondary battery structure - The present invention discloses a secondary battery structure, which comprises a battery body and two terminal assemblies. The battery body has two end-covers; each end-cover has a socket on the inner surface thereof and a through-hole penetrating the socket. Each terminal assembly has a screw and a fastener. The screw is inserted through the through-hole and has a head accommodated in the socket. The fastener is engaged with the screw from the outside of the end-cover to lock a wire or an electric-conduction plate in between the fastener and the battery body, whereby the wire or the electric-conduction plate is unlikely to loosen, wherefore the present invention is suitable for mobile products or frequently-vibrating products. Further, the present invention has simple structure and is suitable for low-cost standardized production. | 10-25-2012 |
20140017555 | SECONDARY BATTERY - A secondary battery including an electrode assembly; a case containing the electrode assembly; a cap plate sealing an opening of the case; a terminal plate electrically connected to the electrode assembly; an electrode terminal electrically connected to the terminal plate; and an insulation layer between the cap plate and the terminal plate and electrically insulating the cap plate and the terminal plate from each other, and the terminal plate includes a first metal layer connected to the electrode terminal, and a second metal layer on the first metal layer, the second metal layer being between the first metal layer and the insulation layer. | 01-16-2014 |
20140356699 | POWER SOURCE ENCAPSULATION - A system includes a power source having a set of power terminals, a cover encapsulating the power source including the set of power terminals and sealing the power source including the set of power terminals within the cover, and a set of conductive contacts passing through the cover, contacting the set of power terminals, and providing conductive access to the set of power terminals of the power source from outside the cover without allowing exposure of the power source to an environment outside the cover. | 12-04-2014 |
20150072222 | RECHARGEABLE BATTERY - A rechargeable battery includes an electrode assembly and a cap plate. The electrode assembly is located in a case of the battery, and the cap plate a cap plate is over an opening of the case. The battery also includes a terminal and a gasket. The terminal includes a plurality of sealing protrusions. The gasket is located between the terminal and cap plate and contacts the plurality of sealing protrusions. Together, the sealing protrusions and gasket establish a barrier which prevents electrolyte solution in the case from reaching and eroding the terminal. | 03-12-2015 |
