Abstract: The present invention discloses a method for chemically marking metal products such as metal ingots and other rough or processed metal materials. More specifically, the aim of the present invention is the use of tracers during the method for casting or other methods for manufacturing metal products. These tracers in turn can be identified by physico-chemical methods for confirming the specification of the product, the source of the products or of other similar elements and to assist anti-counterfeiting measures or the identification of production batches or cycles.

Abstract: There is provided a method for producing an anode for lithium batteries. The method comprises: providing a current collector, forming a layer of protective material thereon, depositing a lithiophilic material on the layer of protective material, and depositing a molten lithium material on the layer of lithiophilic material. The lithiophilic material and the molten lithium material subsequently react to form the anode active material. The current collector and/or at least one other layer of the anode may comprise a continuous 3D structure on a surface thereof. The protective material deposited on the current collector constitutes a barrier between the current collector and lithium in the anode active material, therefore formation of cracks in the current collector is avoided.

Abstract: There are provided an apparatus and a method for producing lithium metal by electrolysis of LiCl in a diaphragmless electrolytic cell. The method and apparatus of the invention make use of a liquid-liquid separator which is at least one film coalescer or at least one centrifugal separator to coalesce or separate lithium metal from the Li metal/electrolysis medium mixture produced in the electrolytic cell. There is also provided a method for producing lithium metal from Li2O in an electrolytic cell, the method comprising feeding Li2O or feeding LiCl produced from Li2O to the electrolytic cell.
