  • Method for drying electrolyte solution
    Patent number: 10505228
    Abstract: The present invention provides a method for producing low-water-content electrolyte solutions. In particular, the present invention provides a method of removing water from a liquid solution comprising a non-aqueous solvent, a hygroscopic metal salt and water. It also provides a method for producing a low-water content electrolyte solution without isolation of the metal salt. The method of the invention is useful in producing low water content electrolyte solutions for batteries such as lithium- or lithium-ion batteries.
    Type: Grant

    Date of Patent: December 10, 2019
    Assignee: Synthio Chemicals, LLC
    Inventors: Joseph Carl Poshusta, Jerry Lynn Martin
  • Process for producing hydrogen bis(fluorosulfonyl)imide
    Patent number: 10099925
    Abstract: The present invention provides a process for producing hydrogen bis(fluorosulfonyl)-imide (HFSI) by fluorination of a liquid hydrogen bis(chlorosulfonyl)imide (HCSI) using a gaseous hydrogen fluoride. In some embodiments, HFSI that is produced is separated from the reaction mixture as a gas and is condensed to collect a liquid HFSI.
