Verfahren zur elektrochemischen Herstellung eines Alkalimetalls aus wäßriger Lösung

摘要

The invention relates to an electrolytic cell which comprises an anode compartment containing an aqueous solution of at least one alkali metal salt, and which comprises a cathode compartment and a solid electrolyte by means of which the anode compartment and the cathode compartment are separated from one another. The invention is characterized in that the portion of the surface of the solid electrolyte which is in contact with the anode compartment and/or the portion of the surface of the solid electrolyte which is in contact with the cathode department have/has at least one additional ion-conducting layer.
