Publication number: 20170133714Abstract: The invention relates to an ionogel that may be used for making a self-supporting film forming a solid electrolyte of an electrochemical device, to such a device incorporating this ionogel and to a process for manufacturing this ionogel. The invention generally applies to all energy storage devices such as supercapacitors or storage batteries (e.g. lithium-ion). An ionogel according to the invention comprises: a polymeric confinement matrix which comprises at least one polylactic acid, and at least one ionic liquid confined in this matrix. According to the invention, this matrix also comprises a polycondensate of at least one sol-gel molecular precursor bearing hydrolysable group(s).Type: ApplicationFiled: November 4, 2016Publication date: May 11, 2017Inventors: David Ayme-Perrot, Philippe Sonntag, Philippe-Franck Girard, Carole Cerclier, Jean Le Bideau, Thierry Brousse

Publication number: 20160164139Abstract: The invention relates to a monolithic ionogel with an organic confinement matrix for at least one ionic liquid, and a method for manufacturing same. An ionogel according to the invention comprises a biopolymer confinement matrix with a cross-linked polysaccharide base and an ionic liquid confined in a network formed by the matrix, and it is such that the polysaccharide has siloxane cross-linking bridges, the ionogel being a chemical gel able to constitute a self-supported solid electrolyte by itself. This ionogel is obtained using a method comprising silanisation of the polysaccharide in a basic aqueous solution by a silanisation agent, and polycondensation of the silanised polysaccharide. In a first embodiment, this method comprises preparing a hydrogel with a polysaccharide base that is silanised and cross-linked by sol-gel, then exchange reactions of solvents with increasing hydrophobicities.Type: ApplicationFiled: July 29, 2013Publication date: June 9, 2016Applicants: Hutchinson, Centre National de la Recherche Scientifique, Universite de NantesInventors: David Ayme-Perrot, Carole Cerclier, Jean Le Bideau, Nela Buchtova, Aurélie Guyomard-Lack, Philippe-Franck Girard

Patent number: 7622422Abstract: A method of preparing an ionic conducting gel in solid form, known as ionogel. The method includes a step of mixing an ionic liquid with at least one molecular precursor containing at least one hydrolyzable group, if necessary in the presence of an acid, such as a carboxylic acid. The mixture is subsequently left to stand for one or more days until a gel is formed by polycondensation of the molecular precursor(s). The gel contains the aforementioned ionic liquid and can be set, in particular in transparent monolithic solid form.Type: GrantFiled: July 2, 2004Date of Patent: November 24, 2009Assignees: Centre National de la Recherche Scientifique, Universite Montpellier II, Universite Blaise Pascal Clermont IIInventors: André Vioux, Jean Le Bideau, Marie-Alexandra Neouze, Fabrice Leroux
