  • Electrode for lithium-ion battery comprising a binder formed from a blend of two polymers, the first polymer being a first polyacrylate or one of its derivatives, the second polymer being a second polyacrylate or a carboxymethyl cellulose or one of their derivatives, ink for producing such an electrode
    Patent number: 11050054
    Abstract: Electrode for a lithium storage battery, or a lithium battery, including: an active electrode material, made from silicon, a conductive agent, a binder comprising a mixture of two polymers: the first polymer having a first molecular weight, the first polymer being a first polyacrylate or one of its derivatives, the second polymer having a second molecular weight, the second polymer being a second polyacrylate or a carboxymethyl cellulose, or one of their respective derivatives. The first molecular weight is less than or equal to 400,000 g/mol and greater than or equal to 150,000 g/mol. The second molecular weight is greater than or equal to 650,000 g/mol and less than or equal to 4,000,000 g/mol.

  • LOW-WEIGHT NEEDLED FABRIC, METHOD FOR THE PRODUCTION THEREOF AND USE OF SAME IN A DIFFUSION LAYER FOR A FUEL CELL
    Publication number: 20180301713
    Abstract: The invention relates to a fabric comprising carbon threads, said fabric having a mass per unit area within the range of 40 g/m2 to 100 g/m2, preferably from 40 g/m2 to 80 g/m2, specifically from 60 g/m2 to 80 g/m2, and characterized in that it comprises staple fibers, said staple fibers extending out from the threads constituting the fabric from which they originate and extending in a direction that is not parallel to the direction of the thread from which they originate and/or in that the fabric is needled. The invention also relates to the use of this fabric in a diffusion layer for a fuel cell and a method for manufacturing this diffusion layer.
