    Abstract: An anode usable in a cell of a lithium-ion battery comprising an electrolyte based on a lithium salt and a non-aqueous solvent, to a process for manufacturing this anode and to a lithium-ion battery having one or more cells incorporating this anode. This anode is based on a polymer composition, obtained by melt processing and without solvent evaporation, that is the product of a hot compounding reaction between an active material and additives having a polymer binder and an electrically conductive filler. The binder is based on at least one crosslinked elastomer and the additives furthermore include at least one non-volatile organic compound usable in the electrolyte solvent, the composition advantageously includes the active material in a mass fraction greater than or equal to 85%.

    Abstract: Polymer composition for an electrode, method, and a lithium-ion battery including same are provided. This composition includes an active material having a graphite usable in the anode, an electrically conductive filler and a cross-linked elastomer binder that includes a hydrogenated acrylonitrile butadiene copolymer (HNBR). The binder includes a non-hydrogenated acrylonitrile butadiene copolymer (NBR) and/or a HNBR with an acrylonitrile content that is at least 40% by weight and cross-linked by thermal oxidation. This method includes: a) mixing the active material, the binder in a non-cross-linked state and the electrically conductive filler, to obtain a precursor mixture of the composition, b) depositing the mixture on a metal current collector so that the mixture forms a non-cross-linked film, then c) thermal oxidation of the non-cross-linked film under an atmosphere containing oxygen at a temperature of between 200 and 300° C., to obtain the electrode in which the binder is cross-linked.

    Abstract: A carbonaceous composition usable to constitute a supercapacitor cell electrode, a porous electrode usable to equip such a cell, a process for manufacturing this electrode and one such cell incorporating at least one such electrode, for example in order to equip an electric vehicle. This composition is usable to be in contact with an aqueous ionic electrolyte, is based on a carbonaceous powder and comprises a hydrophilic binder-forming system. The system may include between 3% and 10% by weight a first crosslinked polymer having a number-average molecular weight Mn of greater than 1000 g/mol and having alcohol groups, and between 0.3% and 3% by weight a second polymer of at least one acid and which has a pKa of between 0 and 6 and a number-average molecular weight Mn of greater than 500 g/mol, the first polymer being crosslinked thermally in the presence of the second polymer.
