A sulfur electrode container is described which includes a metallic liner in foil form with at least two full windings within an outer casing. The liner is substantially corrosion resistant to liquid sulfur, while the outer casing is readily corroded by liquid sulfur. One method of making a sulfur electrode container includes forming a metallic liner in foil form into at least two full windings within the outer casing. Another method of making a sulfur electrode container includes wrapping a metallic liner in foil form into at least two full windings around a sulfur-carbon plug, after which the plug surrounded by the foil, is positioned within an outer casing.

Sulfur electrode container and methods of manufacture

A corrosion resistant contiguous duplex chromium-carbon-iron alloy layer bonded to a steel and other similar ferrocarbon substrate for use as a cell casing for a sodium-sulfur cell. The outer layer includes in excess of 60 weight % chromium. The duplex layer is formed by pack chromizing in a pack of chromium and ammonium halide at elevated temperatures in hydrogen or inert gas atmosphere.

Electrically conducting components of sodium/sulfur batteries subject to the corrosive attack of the cell reactants are protected by aluminiding to provide a conductive, protective coating of a metal aluminide. The protective coating finds particular application in the metal conducting container forming the sulfur compartment, where the metal aluminide reacts with the sulfur and sodium polysulfide to form a protective, doped, aluminum sulfide coating, which is conductive due to the presence of the metal from the container.
