    Abstract: The present application provides for ceramic collars and metal rings for active brazing in sodium-based thermal batteries. The ceramic collar may be an alpha-alumina collar configured for active brazing, and thereby sealing, to outer and inner Ni rings for use in NaMx cells. The portions of the alpha-alumina collar active brazed to the outer and inner Ni rings may be outwardly facing and include inwardly extending recesses. The portions of the outer and inner Ni rings active brazed to the outwardly facing portions of the collar may be inwardly facing. The alpha-alumina collar may include a greater coefficient of thermal expansion than each of the outer and inner Ni rings, and the alpha-alumina collar and outer and inner Ni rings may be configured such that a portion of the outer and inner Ni rings is deformed into the inwardly extending recesses of the alpha-alumina collar after active brazing thereof.

    Abstract: 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.

    Abstract: A combustor for a gas turbine system includes a combustor casing having an interior-establishing wall, and a chamber extending to the interior-establishing wall. In addition, the combustor includes an igniter assembly disposed within the chamber such that a tip of the igniter assembly is positioned radially outwardly from the interior-establishing wall. The igniter assembly includes a first electrode, a second electrode, and an insulator. In addition, the first electrode, the second electrode, and the insulator form a cavity, the second electrode forms an outlet passage extending from the cavity, a maximum cross-sectional area of the cavity is greater than a minimum cross-sectional area of the outlet passage, and the first electrode and the second electrode are configured to ionize gas within the cavity in response to an electrical current applied to the first electrode or to the second electrode.

    Abstract: Embodiments of the present disclosure relate to a spark gap device that includes a first electrode having a first surface and a second electrode having a second surface offset from and facing the first surface. The spark gap device also includes a light source configured to emit light toward at least the first surface such that photons emitted by the light source when the spark gap is operated are incident on the first surface and cause electron emission from the first surface. The light source includes a discharge probe having a third electrode sealed in a tube filled with an inert gas. The spark gap device may not include a radioactive component.

    Abstract: A method for joining a ceramic component to a metallic component is described. At least one initial layer of an active metal is applied to one of the joining surfaces, by a cold spray technique. At least one second layer of a nickel-based braze composition is then applied over the initial layer by cold-spraying. The braze composition and components are then heated, so as to form an active braze joint between them. A method of sealing an open region of a sodium metal halide-based battery is also disclosed, using the brazing technique described herein to form braze joints that seal various components in the battery cells, such as metallic rings and ceramic collar structures.
