  • Crosslinked polymer electrolyte
    Patent number: 10547082
    Abstract: A composite electrolyte can include a crosslinked polymer formed from telechelic precursor polymers having at least two photoactivatable end functional groups and a molecular weight before crosslinking of between about 1,000 and 1,000,000 Daltons (Da); and a lithium (Li) salt. Electrochemical cells and batteries including such electrolytes are also disclosed, along with various methods of manufacture.
    Type: Grant
    Filed: February 14, 2013
    Date of Patent: January 28, 2020
    Assignee: California Institute of Technology
    Inventors: Isabelle Darolles, Simon Jones, Nanditha Nair
  • Fluoride ion battery electrolyte compositions
    Patent number: 10355311
    Abstract: A fluoride ion battery includes a substantially lithium-free anode and cathode. At least one of the anode or cathode contains fluorine, and a substantially lithium-free liquid electrolyte is used for charge transport. The electrolyte is liquid at temperatures below about 200 degrees Celsius, and can be formed from an organic-soluble fluoride salt dissolved in selected classes of solvents.
    Type: Grant

  • Fluoride ion battery compositions
    Patent number: 9166249
    Abstract: A lithium-free, anion based charge transport electrochemical system that uses fluoride ion transporting electrolytes, including ionic liquids, with and without various additives to improve performance, is described. The fluoride ion transporting electrolyte can be wholly or partly an ionic liquid that is typically liquid at temperatures less than 200 degrees Celsius. In other embodiments, electrolytes that remain liquid at less than 100 degrees Celsius are useful.

  • CARBON CATHODES FOR FLUORIDE ION STORAGE
    Publication number: 20130320928
    Abstract: The invention provides fluoride ion host electrodes for use in electrochemical cells. These electrodes include carbon nanomaterials having a curved multilayered structure and a film or particles of a metal-based material. The metal-based material may react with fluorine and may be a transition metal such as silver. The invention also provides electrochemical cells in which the fluoride host electrode serves as at least one electrode of the cell.
