Abstract: The invention relates to a cathode for a metal/air battery comprising at least one active layer produced in an active material and having an air side and a metal side, a current collector and a hydrophobic membrane produced in a hydrophobic material and deposited on the air side of the active layer. Said hydrophobic material has a porous structure and has penetrated into the air side of the active layer so as to form, between the hydrophobic membrane and the active layer, an interpenetration zone of hydrophobic material in the active material, in which there is a concentration gradient of hydrophobic material which decreases in the ingoing direction of air into the cathode.

Abstract: The invention relates to a battery comprising at least a cathode current collector, a cathode, a separator, an electrolyte, an anode and an anode current collector, the cathode being disposed between the cathode current collector and the separator, and the anode being disposed between the separator and the anode current collector, the battery further comprising a sealing gasket disposed on the periphery of the cathode, of the anode and of the separator and connecting the inner peripheral edge of the cathode current collector to the inner peripheral edge of the anode current collector. Said sealing gasket is at least partly made of a viscoelastic elastomeric material.
