Jones, I W; Robinson, G; Bird, T L

In a sodium--sulfur cell, the cathode current collector in the sulfur/polysulfide cathodic reactant comprises a carbon or graphite tube containing a solid metal, e.g., aluminum, core and a liquid metal, e.g., tin or a tin--lead alloy, as a conducting interface between the carbon or graphite tube and the core. In a preferred construction, the current collector is axially located within a cylindrical electrolyte tube, the space between the electrolyte tube and graphite tube containing the sulfur/polysulfides and a graphite felt. The outer surface of the graphite tube in this case may have grooves or recesses to form a sulfur reservoir. 5 figures.
