Publication number: 20020187393Abstract: A battery terminal for a battery case is formed with a circumerentially extending shoulder which engages the inner surface of the battery case when the terminal is installed in an aperture in the case by inserting the terminal in the aperture from the inside of the battery case. A retaining ring is then interference resistance welded to the terminal as the retaining ring is pressed into a seated position against the outer surface of the case. An o-ring seal on the shoulder engages the inner surface of the battery case and seals against leakage of the battery acid. High pressure deformation of the battery case and resulting creep are significantly reduced because the force that is used to press the retaining ring against the outer surface of the battery case is relatively low. Furthermore, the welded joint is almost as strong as the material that the terminal is made of and stronger than the plastic battery case.Type: ApplicationFiled: June 6, 2001Publication date: December 12, 2002Inventors: Venkatasubramanian Ananthanarayanan, Michael Henry Froning, Desra N.

Publication number: 20020182493Abstract: 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.Type: ApplicationFiled: April 12, 2002Publication date: December 5, 2002Inventors: Stanford R.

Publication number: 20020155350Abstract: It has been discovered that the connection between a current collector and a molybdenum terminal pin can be improved by roughening the terminal pin. However, a roughened terminal pin detracts from the integrity of the glass-to-metal seal. To overcome this, a sleeve or couple surrounds that portion of the roughened terminal pin that will be sealed to the insulating glass. The sleeve or couple is welded at each end to the terminal pin, and a glass-to-metal seal is formed between the sleeved terminal pin, the insulating glass, and the metallic lid. The resulting assembly contains a portion of the terminal pin that has a roughened surface and is suitable for making a high strength connection to a current collector of a primary or secondary lithium ion battery, and to a sleeved portion which has a relatively smooth surface that provides a high strength for a glass-to-metal seal.Type: ApplicationFiled: April 23, 2001Publication date: October 24, 2002Inventor: David M.

A recess is formed on the top of the leading end of the pole so as to be easier to melt the upper portion of the pole, and by welding with the inner wall of the penetration hole of the bushing, the annular bump is later melted, and the bushing penetration hole is filled up with the fused lead.Type: ApplicationFiled: April 22, 1998Publication date: July 26, 2001Inventor: AKIRA IWAMURA

Patent number: 6258481Abstract: A battery is delineated comprising, in combination, a battery cover having a Cast on Strap (COS) post extending into an aperture located in a top surface of the battery cover; and a battery terminal bushing, integrally coupled to the battery cover, having a first portion fitting about and coupled to the COS post, and having a second portion extending away from the first portion approximately orthogonally. The second portion of the battery terminal bushing extends through the battery cover and is accessible via an aperture located on a side surface of the battery cover, thereby providing frontal access to battery termination.Type: GrantFiled: October 15, 1998Date of Patent: July 10, 2001Assignee: C&D/Charter Holdings, Inc.Inventors: William J. Ross, Guy L. Pfeifer
