Abstract: The invention relates to electrochemical current sources, more particularly to metal-air current sources, and even more particularly to lithium-air current sources and their electrodes. A cathode comprises a base made of a porous electrically conducting material that is permeable to molecular oxygen, the working surface of which has a copolymer applied thereto, which is produced by the copolymerization of a monomeric transition metal coordination complex having a Schiff base and a thiophene group monomer. The monomeric transition metal coordination complex having a Schiff base can be, for example, a compound of the [M(R,R-Salen)], [M(R,R-Saltmen)] or [M(R,R-Salphen)] type, and the thiophene group monomer can be a compound selected from a thiophene group consisting of 3-alkylthiophenes, 3,4-dialkylthiophenes, 3,4-ethylenedioxythiophene or combinations thereof.

Abstract: The invention is related to a metal-air current source and to its cathode. The cathode includes a base made of porous current-conducting material, permeable for molecular oxygen, to whose operating surface is applied a polymer complex compound of transition metal with the Schiff base, having a stack structure, in which the separate fragments of the said polymer compound are connected to each other through the donor-acceptor interaction, for example the compound of poly-[M(R, R?-Salen)], poly-[M(R, R?-Saltmen)] or poly-[M(R, R?-Salphen)] type.
