Abstract: Ionic compounds containing an anion, and a cation having the following structural formula (1): R1R2R3N+-(linker1)-O-(linker2)-(FC)??(1) 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+1SO3?, where in each case n is at least 1 and at most 10.
