The invention relates to an additive for limiting the corrosion of the collector in an electrochemical system. An additive according to the invention consists of a salt (1 / mM) + X- in which: - (1 / mM) + represents a cation chosen from the proton, cations derived from an alkali metal, from a metal alkaline earth, transition metal, zinc, cadmium, mercury, rare earth or organic cations; the X- anion is an anion whose charge is delocalized, which contains at least one fluorine atom bonded to a heteroatom. The additive is useful in particular for lithium generators having a cathode whose collector is an aluminum. |
