Abstract: 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).

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 that is formed from a passivation material and covers the lithium material film. The cover region may allow a lithium ion flux between an electrolyte and the lithium hosting region and inhibiting irreversible reactions between the lithium hosting region and the electrolyte or surrounding environment.

Abstract: A process for electrowinning a metal can include the steps of: a) conveying an anolyte material and a metal chemical feedstock material along an anolyte flow path within an anolyte chamber; b) conveying catholyte material along a catholyte flow path within a catholyte chamber that has a cathode; c) applying an activation electric potential between the anode and a cathode that is sufficient to electrolyze and liberate metal ions from the metal chemical feedstock material in the anolyte chamber, thereby causing a flux of metal ions to migrate through a porous membrane from the anolyte chamber to the catholyte chamber and a metal product to be formed in the catholyte chamber; and while applying the activation electric potential, extracting a feedstock-depleted anolyte material from the anolyte chamber; and extracting an outlet material comprising the catholyte material and the metal product from the catholyte chamber via a catholyte outlet.

Abstract: A vapor deposition system includes a drum. The drum includes a generally cylindrical drum core. A process ring is fixedly disposed on the drum core at a position radially outward of the drum core. The process ring includes an inner face that extends radially, an outer face that extends radially opposite the inner face, and an outer-facing surface extending between the inner face and the outer face. The outer-facing surface has a plurality of axial channels formed therethrough. A plurality of fluid coolant passages extends through the process ring. An annular gas channel is in communication with the plurality of axial channels. A fluid conduit assembly is configured to supply a fluid coolant to the fluid coolant passages and a thermal coupling gas to the annular gas channel. The axial channels direct thermal coupling gas toward the substrate.

Abstract: Systems and processes for the production of lithium metal from molten salts. Systems can include a ceramic tube affixed by or to a freeze-composite. The freeze-composite includes a matrix, of a salt and a dispersed phase. The freeze is maintained with a cooling collar to maintain a temperature below the melting point of the salt. Systems can include a molten-catholyte and a molten-anolyte each adjacent to separate surfaces of the ceramic tube. The freeze-composite forms a fluidic and non-conductive barrier between the molten-catholyte and the molten-anolyte. Processes include a freeze-composite affixed to the ceramic tube. The ceramic tube is adjacent to a composite collar which is adjacent to a cooling collar; The cooling fluid is passed through the cooling collar. A molten-catholyte is passed along a first surface of the ceramic tube. A molten-anolyte is passed along to a second surface of the ceramic tube.

Abstract: An electrorefining process for refining relatively purer lithium metal from a lithium-alloy feedstock material using a three-layer electrorefining apparatus can include a) providing an anode layer comprising a molten, lithium-alloy feedstock material that includes a combination of lithium metal having a first purity and a carrier material; b) providing an electrolyte layer comprising a molten salt electrolyte material; c) providing a product layer comprising molten lithium metal having a second purity that is greater than the first purity above the electrolyte layer; and d) applying an activation electric potential that is sufficient to electrolyze the lithium-alloy feedstock material between an anode layer and the product layer that is electrically isolated from the anode layer, whereby lithium metal is liberated from the lithium-alloy feedstock material, migrates through the electrolyte layer and collects in the product layer.
