Abstract: Processes are described for the direct or indirect electrochemical alkaliation of an alkali metal deficient electrochemically active material. The processes include an electrolysis step either during the alkaliation of the alkali metal deficient electrochemically active material on an electrode current collector (direct) or during the regeneration of a reducing agent used for the alkaliation of the electrochemically active material (indirect).

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.
