  • Binder for an electrode of an electrochemical system, electrode comprising this binder, and electrochemical system comprising this electrode
    Patent number: 9673480
    Abstract: Binder for an electrode of an electrochemical system having a non-aqueous electrolyte, said binder comprising a first polymer which has functional groups capable of reacting with a crosslinking agent and is crosslinked with said crosslinking agent, the crosslinked first polymer forming a three-dimensional network in which a second polymer chosen from fluoropolymers is imprisoned.
    Type: Grant
    Filed: February 8, 2008
    Date of Patent: June 6, 2017
    Assignees: INSTITUT NATIONAL POLYTECHNIQUE DE GRENOBLE, COMMISSARIAT A L'ENERGIE ATOMIQUE ET AUX ENERGIES ALTERNATIVES
    Inventors: Franck Medlege, Helene Rouault, Naceur Belgacem, Anne Blayo
  • Method for characterizing an ethylene and vinyl acetate copolymer
    Patent number: 9157877
    Abstract: A process for characterizing a copolymer of ethylene and vinyl acetate (EVA) using a differential calorimetry analysis technique. This process is determining one or more values of characteristic(s) of a sample of EVA copolymer, one of which is a level of crosslinking of the sample. The process makes it possible to determine not only the degree of crosslinking, but also the vinyl acetate content and the molecular mass of an EVA sample, in a simple, rapid, easy and precise manner.
