Abstract: Method for cutting soft metals, comprising the use of a cutting tool capable of being set in motion by ultrasonic vibration. The method is employed for cutting components used in the manufacture of an electrochemical storage device, for example, a lithium battery. These components include the anodes, the cathodes, the solid electrolytes, the current collectors and the separators. The method is also employed in a system for manufacturing and/or characterizing an electrochemical storage device.

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.

Abstract: A relithiated Li intercalation material for producing Li metal or an alloy thereof or for pre-lithiating an electrode material as well as an anode and an electrolysis cell comprising same are provided. A method of producing Li metal or an alloy thereof or for pre-lithiating an electrode material is also provided. This method comprises carrying out a Li production electrolysis reaction in the electrolysis cell, wherein the electrolysis cell comprises the relithiated Li intercalation material as an anode, a current collector as a cathode, and an electrolyte comprising a lithium salt.

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: Processes are described for the direct or indirect electrochemical alkaliation of an alkali metal deficient electrochemically active material. The processes include an electrolysis step either during the alkaliation of the alkali metal deficient electrochemically active material on an electrode current collector (direct) or during the regeneration of a reducing agent used for the alkaliation of the electrochemically active material (indirect).

Abstract: A process for the recycling of an electrochemically active material is described. The process comprises the steps of reacting the electrochemically active material with an oxidizing agent or a reducing agent in a solvent without addition of a strong acid, to produce a lithium salt and a delithiated electrochemically active material precipitate. This precipitate is separated from the lithium salt and used in the regeneration of the electrochemically active material.
