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.

Fluoride ion battery electrolyte compositions

Ion storage electrodes formed by coating an underlying substrate with a nanofibrillar film of structured conjugate polymer nanofibers and methods of forming such electrodes are described herein. The electrical properties of the electrodes may be customized by modifying the structure of the polymer nanofibers, the thickness of the nanofiber film, and the pore size of the nanofiber films.

Electrodes incorporating nanostructured polymer films for electrochemical ion storage

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.
