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.

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.
