| 摘要 |
The present invention concerns a metal-oxygen battery comprising, as the electrolyte, a monophasic electrolytic solvent medium comprising at least: - an alkali metal or alkaline earth metal supporting salt, preferably a lithium salt, - a fluorocarbon solvent having an oxygen solubility at least equal to 30% v/v, - 10 to 60% by volume of at least one fluorinated solubilising agent, different from said fluorocarbon solvent, chosen from the mono-, poly- and perfluorinated, saturated, unsaturated and/or aromatic, linear, branched and/or cyclic hydrocarbon compounds, having 4 to 18 carbon atoms, the carbon chain of which bears at least one polar end unit and can be interrupted by one or more heteroatoms chosen from oxygen and sulfur atoms, and the radicals -N(R1)-, -B(R1)- and -P(R1R2)- in which R1 and R2, identical or different, represent a hydrogen atom or a C1 to C4 alkyl radical, and - a carbonate solvent. |
