ABSTRACT:
A cathode cell casing and a hermetically sealed sodium-sulfur cell are disclosed. The metallic cathode cell casing is made of one of several specific metals. The cell casing includes also an opposed anode cell casing portion joined to a ring supporting an inner casing of a solid sodium ion-conductive material. A hermetically sealed sodium-sulfur cell has the above type of casing with a sodium negative electrode in the inner casing and a positive electrode of sulfur in conductive material in the cathode casing portion surrounding the inner casing. A high resistance electrical wire is positioned within the inner casing, contacts its closed end and extends to and contacts the interior surface of the anode casing portion.
