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.
