  • Method for detecting and dosing hydrofluoric acid in an electrolyte containing lithium hexafluorophosphate LIPF6 for lithium batteries
    Patent number: 9719954
    Abstract: A method for detecting and dosing hydrofluoric acid content of an electrolyte containing lithium hexafluorophosphate LiPF6 in lithium batteries, including measuring a variation in weight of a material that can undergo a surface reaction with the hydrofluoric acid in the electrolyte, the variation being determined by a quartz microbalance.
    Type: Grant
    Filed: September 13, 2013
    Date of Patent: August 1, 2017
    Assignee: RENAULT s.a.s.
    Inventors: Gregory Douglade, Jean-Frederic Martin
  • METHOD FOR PREPARING PARTIALLY SURFACE-PROTECTED ACTIVE MATERIALS FOR LITHIUM BATTERIES
    Publication number: 20150295242
    Abstract: The present invention relates to a method for preparing particles intended to be used, as active materials, within a composite electrode for lithium batteries, which are coated with at least one layer of oxide, preferably a layer of metal oxide covering only the areas which are capable of being more reactive with an electrolyte based on lithium hexafluorophosphate LiPF6.
