ABSTRACT:
In a sodium sulphur cell, the cathode current collector in the sulphur/polysulphide cathodic reactant comprises a carbon or graphite tube containing a solid metal, e.g. aluminum, core and a deformable electronic conductor, e.g. graphite felt, 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 sulphur/polysulphides and a graphite felt. The outer surface of the graphite tube in this case may have grooves or recesses to form a sulphur reservoir.
