Lithium sulfur battery

A lithium sulfur battery comprising an electrolyte solvent which comprises at least one fluorosubstituted compound is described. Preferred fluorosubstituted compounds which are predominantly solvents are notably selected from the group consisting of fluorosubstituted carboxylic acid esters, fluorosubstituted carboxylic acid amides, fluorosubstituted fluorinated ethers, fluorosubstituted carbamates, fluorosubstituted cyclic carbonates, fluorosubstituted acyclic carbonates, fluorosubstituted ethers, perfluoroalkyl phosphoranes, fluorosubstituted phosphites, fluorosubstituted phosphates, fluorosubstituted phosphonates, and fluorosubstituted heterocycles. Monofluoroethylene carbonate, cis-difluoroethylene carbonate, trans-difluoroethylene carbonate, 4,4-difluoroethylene carbonate, trifluoroethylene carbonate, tetrafluoroethylene carbonate, 4-fluoro-4-methyl-1,3-dioxolane-2-one, 4-fluoro-4-ethyl-1,3-dioxolane-2-one, 2,2,2-trifluoroethyl-methyl carbonate, 2,2,2-trifluoroethyl-fluoromethyl carbonate are preferred. The solvent may further comprise a non-fluorinated solvent, e.g., ethylene carbonate, a dialkyl carbonate, or propylene carbonate. Use of such fluorinated compound as additive for such batteries and specific electrolyte solutions.

SYNTHESIS OF FLUORINATED α-DIKETONES AND SOME INTERMEDIATES

Reactions of perfluoroalkylcopper compounds with α-ketoacyl chlorides were used for the synthesis of fluorinated α-diketones.Heptafluoropropylcopper prepared from copper bronze and 1-iodoheptafluoropropane reacted with benzoylformyl chloride to give heptafluoro-1-phenyl-1,2-pentanedione, with trimethylpyruvyl chloride to give 2,2-dimethyl-5,5,6,6,7,7,7-heptafluoro-3,4-heptanedione, and with 3,3,4,4,5,5,5-heptafluoro-2-keto-pentanoyl chloride or oxalyl chloride to give tetradecafluoro-4,5-octane-dione.Syntheses of fluorinated acetylenes, cyanohydrins, α-hydroxy acids, α-keto acids, their chlorides, and other intermediates for the syntheses of α-diketones by the above route and by other methods are described.An interesting seven-membered ring containing β-hydroxy ketone was obtained by an intramolecular aldol condensation of a fluorinated bis(methyl) ketone.
