Abstract
The invention relates to a sodium-sulphur type electric cell. The cell includes a cathode tank containing sulphur and an anode tank containing sodium, fixed to an alumina plate, as well as an electrolyte tube immersed in the sulphur, such fixing being effected by disposing an aluminium seal between the tank and the plate and compressing at a temperature close to but less than the melting point of aluminium, at least the cathode tank being advantageously made of chrome-plated steel. The invention is implemented in electric cells for electric propulsion.
