Abstract: There are provided an apparatus and a method for producing lithium metal by electrolysis of LiCl in a diaphragmless electrolytic cell. The method and apparatus of the invention make use of a liquid-liquid separator which is at least one film coalescer or at least one centrifugal separator to coalesce or separate lithium metal from the Li metal/electrolysis medium mixture produced in the electrolytic cell. There is also provided a method for producing lithium metal from Li2O in an electrolytic cell, the method comprising feeding Li2O or feeding LiCl produced from Li2O to the electrolytic cell.
