Patent ID: 8658309

Claim:
An electrochemical cell comprising a positive electrode, a negative electrode and an electrolyte positioned between said positive electrode and said negative electrode, said electrolyte comprising a solution having an inorganic fluoride dissolved in one or more solvents, said solution comprising: said one or more solvents; a dissociating agent provided to said one or more solvents; said dissociating agent comprising one or more compounds selected from the group consisting of a Lewis base and a cation receptor; and said inorganic fluoride dissolved in said one or more solvents having said dissociating agent; wherein said inorganic fluoride is LiF; wherein said dissociating agent and inorganic fluoride are provided in amounts sufficient to generate a concentration of inorganic fluoride dissolved in said one or more solvents greater than or equal to 0.15 M; wherein said negative electrode comprises a negative electrode active material selected from the group consisting of lithium metal, a lithium metal alloy, an intercalation host material, a carbonaceous material and a lithium storage material; and wherein said positive electrode comprises a positive electrode active material selected from the group consisting of an intercalation host material, a carbonaceous material, a subfluorinated carbonaceous material and a fluorine ion storage material.
