Abstract: A process for recycling an electrode material comprising graphene and an electrochemically active material is described. The process comprises a step of adding, in any order, water and a non-miscible solvent to the electrode material, thereby forming a biphasic system comprising an organic phase and an aqueous phase; and a step of separating and filtering the organic phase to recover graphene. The process optionally comprises additional steps of washing, drying, and/or thermally treating. Also described are electrodes including the recycled graphene, as well as the electrochemical cells and their uses.

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: The present technology relates to self-standing electrodes, their use in electrochemical cells, and their production processes using a water-based filtration process. For example, the self-standing electrodes may be used in lithium-ion batteries (LIBs). Particularly, the self-standing electrodes comprise a first electronically conductive material serving as a current collector, the surface of the first electronically conductive material being grafted with a hydrophilic group, a binder comprising cellulose fibres, an electrochemically active material, and optionally a second electronically conductive material. A process for the preparation of the self-standing electrodes is also described.

Abstract: Described is a method or process for modifying the surface of carbon-coated electrochemically active materials such as complex oxides like olivine-type cathode materials. For instance, the surface of the carbon-coated powder material is modified to increase its hydrophobic characteristics. Also, specific groups may be grafted on the carbon surface of cathode material using the diazonium chemistry, for instance, by the spontaneous grafting of aryl ions generated in situ by the diazotization of an arylamine compound.
