Patent ID: 10411318

Abstract:
The present invention concerns a metal-oxygen battery containing, as the electrolyte, a monophasic electrolytic solvent medium having 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 fluorinated solubilizing agent; and a carbonate solvent. The fluorinated solubilizing agent is different from the fluorocarbon solvent; is chosen from the mono-, poly- and perfluorinated, saturated, unsaturated and/or aromatic, linear, branched and/or cyclic hydrocarbon compounds; and has 4 to 18 carbon atoms with the carbon chain having at least one polar end unit and can be interrupted by one or more heteroatoms of oxygen and sulfur atoms and 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.
