The stack holder is of a shape memory material that serves to maintain the anode and cathode in a face-to-face close physical proximity alignment throughout discharge. This is particularly important in later stages of cell life. As the cell discharges, anode active material is physically moved from the anode to intercalate with the cathode active material. As this mass transfer occurs, the cathode becomes physically larger and the anode smaller. This can lead to gaps forming between the anode and the cathode. However, the stack holder inhibits the formation of such gaps by maintaining a compressive force on the electrode assembly throughout cell discharge.Type: GrantFiled: September 17, 2009Date of Patent: November 12, 2013Assignee: Greatbatch Ltd.Inventors: Donald F.

Patent number: 8497037Abstract: It is an object of the present invention to provide an electrode using a current collector made of an aluminum porous body which is suitably used for an electrode for a nonaqueous electrolyte battery and an electrode for a capacitor, and a method for producing the electrode. In the current collector of the present invention, a strip-shaped compressed part compressed in a thickness direction is formed at one end part of a three-dimensional network aluminum porous body and a tab lead is bonded to the compressed part by welding. The width of the compressed part is 2 to 10 mm. Further, the electrode is formed by filling the current collector with an active material.Type: GrantFiled: July 2, 2012Date of Patent: July 30, 2013Assignees: Sumitomo Electric Industries, Ltd., Sumitomo Electric Toyama Co., Ltd.Inventors: Akihisa Hosoe, Kazuki Okuno, Hajime Ota, Koutarou Kimura, Kengo Goto, Hideaki Sakaida, Junichi Nishimura

Patent number: 8323817Abstract: A galvanic cell is disclosed. Generally, the cell includes an alkali metal anode, which electrochemcially oxidizes to release alkali metal ions, and a cathode, which is configured to be exposed to an electrolyte solution. A water-impermeable, alkali-ion-conductive ceramic membrane separates the anode from the cathode. Moreover, an alkali-ion-permeable anode current collector is placed in electrical communication with the anode. In some cases, to keep the anode in contact with the current collector as the cell functions and as the anode is depleted, the cell includes a biasing member that urges the anode against the current collector. To produce electricity, the galvanic cell is exposed to an aqueous electrolyte solution, such as seawater, brine, saltwater, etc.Type: GrantFiled: September 11, 2009Date of Patent: December 4, 2012Assignee: Ceramatec, Inc.Inventor: John Howard Gordon
