A molten salt, membrane electrolyzer apparatus may include an anolyte compartment containing a molten salt anolyte comprising primarily chloride salts and a lithium carbonate (Li.sub.2CO.sub.3) 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.

There is provided an energy management method, comprising steps of conducting (304) electric energy from an energy production plant (110, 112, 114, 140) to an energy storage facility (120, 220), applying, in the energy storage facility (120, 220), the received electric energy on a chemical compound (222) to separate the chemical compound to a first component (224) and a second component (226), and storing (306), in the energy storage facility (120, 220), the first component and the second component separately.

A process for production of metal(s) by molten-salt electrolysis includes direct non-carbothermic chlorinating of ore containing metal oxide(s) to produce metal chloride(s); and electrolysis of molten salt(s) of the metal chloride(s) for electrowinning of metal(s) product.

A process for producing refined lithium metal can include: a) processing a lithium chemical feedstock material using an electrowinning apparatus to produce a crude lithium metal having a first purity; b) combining the crude lithium metal with a carrier material to create a lithium-rich feed alloy; c) introducing the lithium-rich feed alloy as a feedstock material to an electrorefining apparatus and processing the lithium-rich feed alloy using the electrorefining apparatus to separate lithium metal from the carrier material thereby producing i) a refined lithium metal having a second purity that is greater than the first purity and ii) a lithium-depleted alloy that comprises the carrier material and less lithium metal than the lithium-rich feed alloy; and d) extracting the lithium-depleted alloy from the electrorefining apparatus and recycling at least a portion of the lithium-depleted alloy to provide at least a portion of the carrier material used in step b).
