The present invention relates to a lithium-air battery comprising: - a negative electrode comprising a negative-electrode active material; - a positive electrode capable of using oxygen as a positive-electrode active material; and - at least one catholyte layer comprising a catholyte medium comprising a non-aqueous liquid phase solvent in contact with said positive electrode, wherein the catholyte medium comprises a lithium salt and an additive in the form of a salt of a transition metal M, wherein: M is selected from the group consisting of: Mn, Mo, Co, Ni, Cr, Fe, Cu, Zn, Zr, Nb, Ru, Ag, and wherein the molar ratio M/Li in the catholyte medium is less than 0.1. In other aspects, the present invention relates to relates to a process of discharge of such a lithium-air battery and to a metal-oxide discharge product doped with transition metal M obtained through such a process of discharge. |
