Gérard Gebel has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Electrolyte for electrochemical generator
    Patent number: 10833368
    Abstract: Thermotropic ionic liquid crystal molecules, comprising a so-called rigid part, a so-called flexible part bonded covalently, directly or via a spacer, to said rigid part, and one or more ionic groups bonded covalently to said rigid part. Said molecules can be used as electrolytes in an electrochemical device, in particular a lithium-ion battery.
    Type: Grant

  • PROCESS FOR PREPARING A GELLED ELECTROLYTE
    Publication number: 20200106083
    Abstract: The invention relates to a process for functionalizing the electrically conductive or semi-conductive surface of an electrode by electro-grafting of a polymeric film obtained from an ionic liquid monomer, the cation of which bears at least one electro-polymerizable function. The invention is also directed toward a process for preparing a gelled electrolytic membrane at the surface of an electrode, by gelling the electro-grafted polymeric film, and also to the use of the electrode/electrolytic membrane assembly thus obtained in a lithium battery.

  • Polymer compositions that conduct lithium ions for electrochemical lithium generator
    Patent number: 10497973
    Abstract: The invention relates to polymer compositions that conduct lithium ions including the following ingredients: at least one ionic polymer from the polymerization of an ionic liquid, the cation of which bears at least one polymerizable function; at least one lithium salt; and at least one non-ionic polymer, the composition being a solid composition, i.e., a composition devoid of water and organic solvent(s). The invention also relates to the use of the polymer compositions for entering into the formation of electrolytic membranes of electrochemical lithium generators.

  • Interpenetrating polymer networks and uses thereof
    Patent number: 8703832
    Abstract: Interpenetrating polymer networks comprising a first network of polymer A formed from monomers, at least one of which contains an aromatic group functionalized with a cation-exchange group, and a second network of polymer B formed from monomers, at least one of which contains a fluorinated group (RF). Use of these interpenetrating polymer networks for manufacturing fuel cell membranes.
