摘要： The present application describes a process for the preparation of titanium-based compounds having an anatase type structure with cationic vacancies arising from a partial substitution of oxygen atoms by fluorine atoms and hydroxyl groups. Electrochemically active materials comprising the titanium-based compounds for use in lithium-ion battery electrodes are also described.

摘要： A method for preparing a ceramic from an inorganic base material in the form of a powder with a high boiling point, including a step in which the powder of the inorganic base material is mixed with a second inorganic component which is also in powder form and which serves as a dopant for the inorganic base material. The dopant comprises a single inorganic material or a mixture of at least two inorganic materials that have a dopant effect on the inorganic base material. The method also includes a sintering step performed at a high temperature. Owing to the high density thereof, the resulting ceramics are suitable for use as a target element. The films and electrodes obtained from said ceramics have particularly beneficial properties.

摘要： A method of preparing an electrochemical electrode which is partially or totally covered with a film that is obtained by spreading an aqueous solution comprising a water-soluble binder over the electrode and subsequently drying same. The production cost of the electrodes thus obtained is reduced and the surface porosity thereof is associated with desirable resistance values.

摘要： 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.

摘要： Crosslinked polymers and their uses in electrochemical systems, for example, as electrolyte membrane, are described. More precisely, these crosslinked polymers are formed by the crosslinking of a random copolymer based on monomers of glycidyl methacrylate or acrylate and of poly(ethylene glycol) methyl acrylate or methacrylate with a volatile polyamine crosslinking agent.
