Patent number: 7217473Abstract: 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 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.Type: GrantFiled: September 9, 2004Date of Patent: May 15, 2007Assignee: Ovanic Battery Company, Inc.Inventors: Stanford R. Ovshinsky, Dennis A. Corrigan, Srinivasan Venkatesan, Subhash K. Dhar, Arthur Holland, Donn Fillmore, Lin Higley, Philippe Gow, Ronald Himmler, Nick Karditsas, Kenneth Laming, Anthony Osgood

Patent number: 6878485Abstract: 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: GrantFiled: April 12, 2002Date of Patent: April 12, 2005Assignee: Ovonic Battery Company, Inc.Inventors: Stanford R. Ovshinsky, Dennis A. Corrigan, Srinivasan Venkatesan, Subhash K. Dhar, Arthur Holland, Donn Fillmore, Lin Higley, Philippe Gow, Ronald Himmler, Nick Karditsas, Kenneth Laming, Anthony Osgood

Patent number: 5472802Abstract: 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.Type: GrantFiled: October 25, 1993Date of Patent: December 5, 1995Assignee: Ovonic Battery Company, Inc.Inventors: Art Holland, Kevin Dean, Donn Fillmore
