Sodium sulfur cells. [Tubular sodium-sulfur battery]

Patent ·
OSTI ID:7362742
A sodium--sulfur cell comprises inner and outer tubes, the inner tube constituting the solid electrolyte for the cell. The interior of the inner tube defines the anode compartment of the cell, and the space between the inner and outer tubes defines the cathode compartment of the cell. The inner tube contains metal wool and/or a plate spaced from the inner surface of the inner tube to cause molten sodium to be distributed over the inner surface of the inner tube by capillary action. The inner and outer tubular members are closed at one end by a compression seal assembly. The seal assembly comprises a flange on the inner tubular member engaging the end of the outer tubular member to close the end of the outer tubular member, a closure member engaging the flange to close the inner tubular member, and a clamp fitting over the closure member and held in position by the outer tubular member.
