Abstract
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.
