Abstract
A metal-air battery includes a housing having an aperture for the passage of air and a pair of electrodes that extend from the housing. An air cathode may be interconnected with one of the electrodes and an anode may include a metal foil that is interconnected with another of the electrodes. A separator may be interposed between the air cathode and the metal foil and a barrier layer may surround the metal foil. The barrier layer may function to substantially reduce the passage of moisture to the metal foil. A method of making a metal-air battery is also presented.
