Sodium-sulphur type electric cell

摘要

The invention relates to an electric cell of the sodium-sulphur type particularly adapted for undergoing complete recharging. It comprises a cathode tank containing sulphur, an anode tank containing sodium, these reagents being separated by a solid electrolyte tube disposed in said cathode tank fitted with graphite felt washers ensuring cathode collection of the current generated, wherein said electrolyte tube is surrounded by a grating which is connectable to the negative terminal of the recharging current source by means of a resistor. The invention is used in cells for electric vehicles.
