Solvents and novel electrolytic compositions having a large range of stability and high conductivity
Patent number: 8737039Abstract: The present invention is concerned with novel polar solvents and novel electrolytic compositions comprising such solvents, and having a high range of stability, as required for applications in the field of electrochemistry. The present solvents have a highly polar amide function, and preferably combine with a salt soluble in the solvent and having an anion with a delocalized charge, and at least one polymer, to form an electrolytic composition.Type: GrantFiled: February 7, 2011Date of Patent: May 27, 2014Assignees: ACEP Inc., Centre National de la Recherche Scientifique, Universite de MontrealInventors: Christophe Michot, Dany Brouillette, Daniel Baril, Jean-Yves Bergeron, Michel Armand -
Patent number: 8241541Abstract: The invention provides a pre-mix of positive electrode material in transportable solid form comprising polymer and solid particles of electrochemically active material and/or electronically conductive additives and a process for preparing a pre-mix positive electrode in transportable solid form. The pre-mix positive electrode material may also comprise an alkali metal salt either dissolved or dispersed in the mixture. The invention also provides making a cathode film from the transportable solid pre-mix of positive electrode material.Type: GrantFiled: August 9, 2007Date of Patent: August 14, 2012Assignee: Bathium Canada Inc.Inventors: Alain Vallee, Paul-Andre Lavoie, Patrick Leblanc, Regis Gagnon, Fabrice Regisser, Dany Brouillette

Patent number: 7198870Abstract: A polymer matrix electrolyte (PME) includes a polyimide, at least one salt and at least one solvent intermixed. The PME is generally homogeneous as evidenced by its high level of optically clarity. The PME is stable through harsh temperature and pressure conditions. A method of forming a PME includes the steps of dissolving a polyimide in at least one solvent, adding at least one salt to the polyimide and the solvent, wherein said polyimide, salt and solvent become intermixed to form the PME, the PME being substantially optically clear.Type: GrantFiled: July 29, 2005Date of Patent: April 3, 2007Assignees: Solicore, Inc., Avestor Limited PartnershipInventors: C. Glen Wensley, Alain Vallée, Dany Brouillette, Scott Gustafson
