  • Pentacyclic anion salt and use thereof as an electrolyte
    Patent number: 8927160
    Abstract: The invention relates to a pentacyclic anion salt and to the use thereof in electrolyte compositions. The compound comprises 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 perfluoroalkyl 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 from 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.

  • PROCESS FOR MODIFYING THE INTERFACIAL RESISTANCE OF A METALLIC LITHIUM ELECTRODE
    Publication number: 20090280405
    Abstract: The invention relates to a method of modifying the interfacial resistance of a lithium metal electrode immersed in an electrolytic solution, which consists in depositing a film of metal oxide particles on the surface of this electrode. The invention also relates to a lithium metal electrode, the surface of which is covered with a film of metal oxide particles, and to a battery of the lithium metal type.
