Title: FLUORINATED IONIC LIQUIDS WITH HIGH OXYGEN SOLUBILITY FOR METAL-AIR BATTERIES
Abstract:
The present invention relates to ionic compounds containing an anion, and a cation having the following structural formula (1): R1R2R3N+-(|inker1)-O-(iinker2)-(FC) wherein: - R1 and R2 either linear or branched alkyl groups or together form a N-heterocylic ring with the nitrogen atom to which they are joined;- R3 is linear or branched alkyl group; - linker1 and linker2 are alkylene chains or polyether chains; and - the group FC is a fluorinated alkyl group, as well as an electrolyte material comprising such an ionic compound and a metal salt, and metal-air batteries using such an electrolyte material. The invention also relates to a metal-air battery containing an electrolyte material, wherein the electrolyte material comprises at least one ionic compound and a metal salt, and wherein at least one ionic compound contains an anion CnF2n+1COO- or CnF2n+1S03-, where in each case n is at least 1 and at most 10.
