ABSTRACT:
In a sodium-sulphur cell having a solid electrolyte and a cathode current collector with a porous conductive matrix, e.g. carbon or graphite felt, in the region between the electrolyte and the current collector, the matrix is formed of a plurality of discrete elements with electronically conductive material, e.g. graphite foil, between the elements extending across the region between the current collector and the electrolyte to increase the conductivity across that region.
