    • A lithium sulfur battery comprising 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, and 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-l,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 my further comprise non-fluorinated solvents, e.g. ethylene carbonate, a dialkyl carbonate or propylene carbonate. The invention also concerns the use of fluorinated compounds as additive for such batteries and specific electrolyte solutions.
