Patent number: 9005793Abstract: Systems and methods for obtaining and/or maintaining a column height of an electrolyte relative to a separator surface within an energy storage device. Embodiments of the invention provide a wicking component, a current collector, and a bias component. The current collector is positioned to force the bias component to press the wicking component tight to an inner surface of a separator. The bias component maintains contact between the wicking component and the surface of separator and creates a capillary gap in which sodium wicks.Type: GrantFiled: December 3, 2012Date of Patent: April 14, 2015Assignee: General Electric CompanyInventors: Alec Roger Tilley, Hiroshi Ohata, Koichi Kanie

Patent number: 9005797Abstract: A battery includes a stack of bipolar individual battery cells, each of which includes an electrode stack and two sheet metal covers bounding the individual battery cell at least in the stacking direction. The electrode stack is connected to at least one of the sheet metal covers by at least one weld. In the region of the at least one weld, the sheet metal cover welded to the electrode stack and/or the sheet metal cover of the adjacent individual battery cell in contact with the sheet metal cover is/are of a set-back design. As a result, the sheet metal covers of adjacent individual battery cells do not have any contact in the region of the at least one weld.Type: GrantFiled: July 3, 2010Date of Patent: April 14, 2015Assignee: Daimler AGInventors: Dirk Schroeter, Jens Meintschel, Martin Ertle, Rainer Kaufmann, Claudia Brasse, Claus-Rupert Hohenthanner, Joerg Kaiser
