Abstract: A cathode composition is presented. The cathode composition includes an alkali metal halide and an electroactive metal. The electroactive metal includes a first population of particles that is present in a range at least about 50 weight percent of a total weight of the electroactive metal. A specific surface area of the first population of particles is lower than 0.2 m2/g. An electrochemical cell and an energy storage system including the cathode composition are also presented.

Abstract: An electrochemical cell is described, including an anodic chamber and a cathodic chamber separated by an electrolyte separator tube, all contained within a cell case. The cell also includes an electrically insulating ceramic collar positioned at an opening of the cathodic chamber, and defining an aperture in communication with the opening; along with a cathode current collector assembly; and at least one metallic ring that has a coefficient of thermal expansion (CTE) in the range of about 3 to about 7.5 ppm/° C., contacting at least a portion of a metallic component within the cell, and an adjacent ceramic component. An active braze alloy composition attaches and hermetically seals the ring to the metallic component and the collar. Sodium metal halide batteries that contain this type of cell are also described, along with methods for sealing structures within the cell.
