Patent number: 8470469Abstract: A gasket is for use in a starved electrolyte bipolar battery. The gasket may be made from a hydrophobic material in the shape of a frame to prevent the creation of an electrolyte path between adjacent cells when mounted in a battery. The frame may be designed to at least partially encompass a biplate when mounted in a bipolar battery, and include a device or way to permit gas passage through the gasket. The gasket may be made from a material with deformable properties to provide a sealing to a biplate and/or endplate when mounted in a bipolar battery, whereby an outer pressure tight seal of the battery may be obtained. A starved bipolar battery and a method for manufacturing a starved bipolar battery are also disclosed.Type: GrantFiled: September 3, 2008Date of Patent: June 25, 2013Assignee: Nilar International ABInventors: Neil H.

Patent number: 8053111Abstract: A biplate assembly may include a biplate, a negative electrode and a positive electrode. A method for manufacturing the biplate assembly may involve selecting the size of the biplate and arranging the positive electrode, which is formed by a compressed first powder, to a first side of the biplate. The first powder contains positive active material. The method may also involve arranging the negative electrode, which is formed by a compressed second powder, to a carrier arranged within the biplate assembly. The second powder contains negative active material. The carrier may be a side opposite to the first side of the biplate.

Patent number: 7258949Abstract: The present invention relates to a bipolar battery, especially a NiMH battery, having: a sealed housing, a negative end terminal, a positive end terminal, and at least one biplate assembly comprising a biplate, a positive and a negative electrode. A separator is arranged between each negative and positive electrode forming a battery cell, said separator includes an electrolyte. An inner barrier of a hydrophobic material is arranged around at least one electrode, whereby said inner barrier prevents an electrolyte path from one cell to another cell, and a frame is present to provide predetermined cell spacing between each biplate and/or biplate and end terminal. The frame is attached in such a way to each biplate to permit ambient gas to pass between adjacent cells, thereby creating a common gas space for all cells in the battery. The invention also relates to a method for manufacturing a bipolar battery.Type: GrantFiled: May 9, 2003Date of Patent: August 21, 2007Assignee: Nilar International ABInventors: Lars Frederiksson, Neil H.

Patent number: 5599641Abstract: A terminal connector assembly provided for conducting electrical current from an electrolytic device through the wall of a case containing the device for preventing leakage of electrolyte from the case. The terminal connector includes a terminal insert mounted within the case wall. The insert contains a first end portion projecting through the wall forming an exterior connection member. A second end portion is laterally spaced from the first end portion and forms an interior connection member remote from the exterior connection member. A mechanism is provided for substantially reducing the transmittal of mechanical loads from the first end potion to the second end portion. A member is provided for electrically interconnecting the interior connection member with the electrolytic device within the case. Finally, a mechanism seals the connection between the electrically interconnecting member and the interior connection member to prevent leakage of electrolyte from the device.Type: GrantFiled: April 20, 1994Date of Patent: February 4, 1997Assignee: Gylling Optima Batteries ABInventors: Larry K.

Patent number: 4578324Abstract: An active cooling system (40, 41) for cooling electrochemical cells (11) that are arranged in a stack (9) in a fuel cell or battery (3). The cooling system (40, 41) comprises cooling panels (15, 16) carrying a cooling fluid that flows adjacent to, and parallel to the plane of, each cell (11). The rate of cooling fluid flow past each cell (11) is made to be substantially equal, so that each cell (11) experiences substantially the same cooling environment, adding to the longevity of the fuel cell or battery (3). This can be accomplished by equalizing the resistance to cooling fluid flow for each cooling path (12), e.g., by using pressure equalizing, monotonically increasingly sized orifices (28) in an input manifold (25). Dual cooling panels (15, 16) are preferably employed, in a counterflow mode. The panels (15, 16) may be divided into parallel channels (33). Heat pipe panels (35) containing a two-phase fluid may be used in lieu of panels (15, 16) that contain cooling fluid in a single state.Type: GrantFiled: October 5, 1984Date of Patent: March 25, 1986Assignee: Ford Aerospace & Communications CorporationInventors: Charles W. Koehler, Gerrit van Ommering, Neil H. Puester
