Abstract
An alkali metal sulphur cell has an outer tubular casing and an inner tubular solid electrolyte whose interior constitutes the cathode compartment of the cell. The outer tubular casing and the tubular solid electrolyte are spaced apart to define an annular space, at least the part of which adjacent the outer surface of the tubular solid electrolyte constitutes the anode compartment of the cell. Means are provided for causing the alkali metal to be distributed over the outer surface of the tubular solid electrolyte. Barrier means additional to the solid electrolyte are disposed between the sulphur material and at least a part of the outer casing. The barrier means may comprise a coating on one or both surfaces of the tubular solid electrolyte, alkali metal flow restrictor means or a coating on at least a part of the inner surface of the outer casing.
