Ionic conducting material having good anticorrosive properties

A battery, comprising an positive electrode, a negative electrode and an electrolyte, wherein the electrolyte comprises at least one ionic compound in an aprotic solvent, wherein the ionic compound is represented by one of the formulae (1/mM)+((FSO2)2N)—, (1/mM)+((FSO2)3C)− or (1/mM)+((FSO2)2CQ)−, wherein:

• Q is —H, —COZ or Z;
• each substituent Z independently denotes a fluorine atom;
• M is a cation selected from the group consisting of an alkali metal, an alkaline-earth metal a transition metal, zinc, cadmium, mercury, a rare earth, diazonium ion, phosphonium ion, sulphonium ion, oxonium ion, and an organic cation NuR+, wherein Nu is selected from the group consisting of ammonia, alkylamines, pyridines, imidazoles, amidines, guanidines and alkaloids, wherein R is hydrogen, an alkyl group or an oxaalkyl group containing from 1 to 20 carbon atoms or an aryl group containing from 6 to 30 carbon atoms;
• and
• m is the valency of the cation M.
