    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.

    Abstract: The invention relates to a sodium-sulphur battery for electrical drive. It is formed by elements each comprising a cathode tank containing sulphur, a solid electrolyte tube closed at its lower end, containing sodium and arranged in the said cathode tank, a ceramic insulating support for keeping the said electrolyte tube in the said cathode tank, an anode tank containing a supply of sodium, that battery being characterized in that it comprises m groups of n modules each comprising p elements, those elements being electrically interconnected in parallel in each of the modules by means of plates connected to the bottoms of the said cathode tanks and anode tanks respectively, each of the said plates comprising a substantially central bore. The invention is implemented for propelling all electric vehicles.
