ABSTRACT:
The invention relates to an electric cell of the sodium-sulphur type, suitable more particularly for undergoing a complete recharge. 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 which is fitted with graphite felt washers ensuring cathode collection of the current generated, wherein some washers are disposed to have an edge distant from the wall of said electrolyte tube in order to avoid depositing sulphur on said tube during recharging. The invention is used in electric cells for electric vehicles.
