Abstract (en)
[origin: WO2021012055A1] A molten salt, membrane electrolyzer apparatus may include an anolyte compartment containing a molten salt anolyte comprising primarily chloride salts and a lithium carbonate (Li2CO3) feed material. A first and second electrode assemblies each having respective anodes, cathode housings proximate the first anode within the anolyte compartment and in fluid contact with the molten salt anolyte and having a primary transfer portion comprising a porous membrane and cathodes positioned within the first catholyte compartment so that the primary transfer portion is disposed between respective anode and cathode. A power supply can be configured to apply an electric potential between the first anode and the first cathode that is sufficient to initiate electrolysis of lithium carbonate and is greater than the electric potential required to initiate LiCl electrolysis.
