  • FLUORIDE ION BATTERY COMPOSITIONS
    Publication number: 20120164541
    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.

  • Polymer materials as binder for a CFx cathode
    Publication number: 20110183204
    Abstract: Lithium anode based battery systems can use polymeric binding materials to act as particulate binders for fluorinated carbon based electrodes. The binders mechanically hold electrochemically active particles together, while inhibiting lithium fluoride crystallization that generates unwanted heat release in a discharging battery. Polymeric binders that include positively-charged groups, negatively-charged groups, electron deficient ?-anion receptor groups, or boronate-based fluoride receptor group can be used alone or in combination.

  • Non-Aqueous Electrochemical Cell using Fluorinated Carbon-carbon Composite Electrode
    Publication number: 20110143208
    Abstract: Non-aqueous electrochemical cells, and batteries formed of such cells are described. More particularly, use of electrochemical cells containing sub-fluorinated carbon-carbon composite as an active material for the positive electrode of such cells and batteries is disclosed. When used in conjunction with lithium anodes and a non-aqueous electrolyte, the electrochemical cell provides high discharge rate and excellent capacity utilization.

  • Fluoride Ion Battery Electrolyte Compositions
    Publication number: 20110143219
    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.
