Abstract: The present application provides configurations, components, assemblies and methods for sealing cells of sodium-based thermal batteries, such as NaMx cells. In some embodiments the cells may include an integrated bridge member hermetically sealed to an electrically conductive case and a ceramic collar of the cell to hermetically seal an anodic chamber of the cell. In some embodiments the cells may include the ceramic collar hermetically sealed to an electrolyte separator tube of the cell to hermetically seal the anodic chamber of the cell. In some embodiments the anodic chamber may be defined, at least in part, by the case, integrated bridge member, ceramic collar and electrolyte separator tube. In some embodiments the cells may include a current collector hermetically sealed to the ceramic collar, and a cap member hermetically sealed to the current collector tube to hermetically seal a cathodic chamber of the cell.
