  • Flexible electrode-separator elements and processes for their preparation
    Patent number: 11081761
    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.
    Type: Grant
    Filed: July 21, 2017
    Date of Patent: August 3, 2021
    Assignees: HYDRO-QUÉBEC, TRANSFERT PLUS, S.E.C.
    Inventors: Nicolas Delaporte, Diby Benjamin Ossonon, Karim Zaghib, Daniel Belanger
  • Process for recycling graphene from an electrode material
    Patent number: 10811736
    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.
