Abstract: 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.

Abstract: A multi-layer, lithium anode assembly for use in a lithium-based battery can include a substrate region having a current collector comprising a continuous copper foil that is between 4 and 10 microns thick and has a lithium compatible support surface. A lithium hosting region may overlie the support surface and may include a lithium material film deposited directly onto the support surface via thermal evaporation and having a thickness that is between 1 microns and 10 microns. A cover region may be located outboard of the lithium hosting region and may have a cover film comprising a lithiophilic material deposited directly onto an exposed surface of the lithium material film via physical vapour deposition, thereby enhancing mobility of lithium ions travelling through the cover region and between an electrolyte and the lithium hosting region so that dendrite formation is inhibited when lithium is deposited in the lithium hosting.
