  • Publication number: 20190288260
    Abstract: This application describes a process for the preparation of flexible electrode-separator elements or assemblies, which includes the application of an electrode material on the separator. The electrode material comprises graphene, for instance produced by graphite exfoliation. The electrode-separator elements obtained by the process as well as their use in electrochemical cells are also described.

  • Publication number: 20190288349
    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.

  • Patent number: 10302016
    Abstract: The invention relates to a support providing a complete connection between a degassing pipe (3) and a turbine shaft (2), said support including a plurality of outer contact spans (41a) intended to bear on the inner walls of the turbine shaft to secure the degassing pipe with respect thereto, characterized in that the different spans are each bordered by at least one elastomer insert (41g) which contributes to the protection of the turbine shaft during insertion of the support therein.

  • Publication number: 20180138512
    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.
