Patent number: 9362537Abstract: An electrochemical cell is presented. The cell includes a housing having an interior surface defining a volume, and an elongated, ion-conducting separator disposed in the volume. The separator usually extends in a vertical direction relative to a base of the housing, so as to define a height dimension of the cell. The separator has a first circumferential surface defining a portion of a first compartment. The cell further includes a shim structure disposed generally parallel to the first circumferential surface of the separator between the interior surface and the first circumferential surface of the separator. The structure includes at least two shims, a first shim and a second shim, that substantially overlap each other. An energy storage device including such an electrochemical cell is also provided.Type: GrantFiled: July 26, 2013Date of Patent: June 7, 2016Assignee: General Electric CompanyInventors: Guillermo Daniel Zappi, Mohamed Rahmane, Benjamin Hale Winkler, James Lowe Sudworth, Roger Neil Bull, Charles Dominic Iacovangelo

Patent number: 9059484Abstract: An electrochemical cell includes an outer casing defining at least a portion of an anode electrode chamber, an ionically conducting separator disposed within the outer casing, an inner surface of the separator defining a cathode electrode chamber, a cathode electrode disposed within the cathode chamber, a conductive current collecting body coupled with the cathode electrode, an alkali metal-containing electrolyte disposed in the cathode electrode chamber, and a sealing body coupled with the outer casing and sealing the anode electrode chamber from an external atmosphere disposed outside of the outer casing. The electrolyte supplies alkali metal through the separator to the anode electrode chamber in response to an electric charge applied to the conductive current collecting body. A first content of a gas component in the anode electrode chamber is in the anode electrode chamber in an amount that is less than an amount of a second content of the gas component in ambient air.Type: GrantFiled: August 13, 2010Date of Patent: June 16, 2015Assignee: GENERAL ELECTRIC COMPANYInventor: James Lowe Sudworth

Publication number: 20150004456Abstract: Fin-based current collectors provide high performance and cost savings in electrochemical cells. Embodiments of the invention provide a current collector for a sodium-metal halide electrochemical cell having at least one substantially flat and elongated metal fin being electrically conductive and having at least one bend with respect to a dominant longitudinal axis of the current collector. The at least one substantially flat and elongated metal fin is configured to be joined to a metal ring of the electrochemical cell via one of welding or brazing.Type: ApplicationFiled: July 16, 2013Publication date: January 1, 2015Inventors: ROBERT CHRISTIE GALLOWAY, ROGER NEIL BULL, JAMES LOWE SUDWORTH, PAUL SUDWORTH, CONNOR BRADY, MICHAEL BARONE

Publication number: 20130143110Abstract: A terminal apparatus for an energy storage cell is presently disclosed. The terminal apparatus includes a terminal body with a peripheral edge extending substantially around a perimeter of the terminal body such that the terminal body is configured to be secured to a cell housing to retain an electrochemical cell in the cell housing, a terminal connector extending from the peripheral edge forming a first terminal for an energy storage cell, a sealable vacuum port extending through the terminal body, and an aperture in the terminal body configured to receive a second terminal of the energy storage cell. A method of manufacturing an energy storage cell is also disclosed.Type: ApplicationFiled: December 1, 2011Publication date: June 6, 2013Inventors: Roger Neil BULL, Neil Anthony Johnson, Owen Scott Quirion, James Lowe Sudworth, Paul Sudworth, Alec Roger Tilley, Edward James Balaschak
