ABSTRACT:
In the manufacture of a sodium sulphur cell, the sodium is gas-pressurized to force it upwardly over a surface of the electrolyte by means of a capsule of material, e.g. sodium azide, which releases an inert gas on heating, so enabling the cell to be sealed before the sodium is pressurized.
