Patent number: 9452987Abstract: A pentacyclic anion salt is provided for use thereof in electrolyte compositions. The compound has an inorganic, organic or organometallic cation M of valency m (1?m?3) and m anions corresponding to the formula (I) in which Rf is a —CFZ?Z? group in which Z? is F or a perflouroalkyl group having from 1 to 3 carbon atoms, and Z? is an H, F or Cl group, an optionally fluorinated or perfluorinated alkoxy group having from 1 to 5 carbon atoms, an optionally fluorinated or perfluorinated oxaalkoxy group having 1 to 5 carbon atoms or an optionally fluorinated or perfluorinated alkyl group having from 1 to 5 carbon atoms; Z? being other than F when Z? is F. An electrolyte composition comprises said salt in solution in a liquid solvent or a polymer solvent.Type: GrantFiled: December 1, 2014Date of Patent: September 27, 2016Inventors: Michel Armand, Sylvie Grugeon, Stephane Laruelle, Maria Bukowska, Przemyslaw Szczecinski, Wladislaw Wieczorek, Leszek Niedzicky, Bruno Scrosati, Stefania Panero, Priscilla Realle

Publication number: 20130298386Abstract: The invention relates to a method for producing a battery using A+ (Li+ or Na+) as an electrochemical carrier, as well as to the resulting batteries. The method involves assembling together a negative electrode, a positive electrode, and an electrolyte, and then exposing the assembly to a firm charge at the operating temperature of the battery. The electrolyte is a ceramic or a solution of an A+ salt in a polar liquid, a polymer, or the mixture thereof. The active material of the negative electrode is a material which has a redox couple, the potential of which is 0 V to 1.6 V relative to the A+/A+ couple. The active material of the positive electrode is a material which has a redox couple, the potential of which is higher then that of the couple of the negative electrode.Type: ApplicationFiled: June 16, 2011Publication date: November 14, 2013Applicants: UNIVERSITE DE PICARDIE JULES VERNE, CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUEInventors: Jean-Marie Tarascon, Michel Armand, Shanmukaraj Devaraj, Sylvie Grugeon, Stephane Laruelle
