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: 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: 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.
