ABSTRACT:
An electrolytic cell for metal, particularly Mg, production includes a cathode or intermediate bipolar electrode having a cathodic face provided with a plurality of small cavities shaped to trap droplets of molten metal formed during electrolysis. The cavities help the metal droplets to coalesce and reduce the extent of back reaction with e.g. chlorine generated at the anode.
