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.

Alkali-hydroxide modified poly-vinylidene fluoride/polyethylene oxide lithium-air battery

An anode for a metal-air battery has an electrode and a metal foil interconnected with the electrode. A barrier layer surrounds the metal foil and includes a polymer blend that substantially reduces the passage of moisture therethrough while permitting the passage of ions therethrough. A method of making the barrier layer is also presented.
