Abstract: A process for electrowinning a metal using a flow-through electrowinning apparatus 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: Zinc containing electrodes and anodes, processes for their production, and cells including said electrodes and anodes are disclosed. The electrodes and anodes can include zinc adjacent to a copper current collector and carrying lithium metal. Processes include the deposition of zinc and then lithium onto the current collector and the electrochemical products include the electrodes and anodes in a lithium-metal cell.

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: Lithium anodes that include lithium metal sheets or foils welded to current collectors are described with processes for their formation. One example is a lithium metal anode for use in a battery that includes a current collector carrying proximal lithium metal layers that carry distal lithium metal layers. The proximal lithium metal layers having thicknesses of about 100 nm to about 25 μm and having greater than about 99.5 wt. % lithium, the distal lithium metal layers having thicknesses of about 10 μm to about 200 μm and having greater than about 90 wt. % lithium. Notably, the proximal and distal lithium differ in their average grain sizes with the distal average grain size but at least 1.5 times the size of the proximal average grain size.

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.

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.
