ABSTRACT:
An alkali metal-sulphur cell has an outer tubular casing and an inner tubular solid electrolyte dividing the cell into anode and cathode compartments and whose interior provides one of such compartments. The outer tubular casing and the tubular solid electrolyte are spaced apart to define an annular space, which provides the other compartment of the cell.
A primary porous coating is provided on at least one surface of the solid electrolyte and an outer layer is provided on the primary porous coating, the outer layer being more dense than the primary porous coating.
