Abstract

Disclosed herein is a method of controlling the morphology of a metal product in an electrolytic cell comprising the steps of (a) providing an electrolytic cell comprising a molten electolyte, a cathode having a non-uniform current distribution in contact with the molten electrolyte, and an anode in contact with the molten electrolyte; (b) providing a metal compound to the electrolyte; and (c) applying either a fixed voltage or a fixed current across the anode and the cathode thereby depositing metal on the cathode.
