Abstract: A metal-air battery includes a metal anode including at least one of zinc, aluminum, magnesium, iron, and lithium. The metal-air battery also includes an ion exchange material provided within the battery for controlling material transport within the battery. The ion exchange material may be provided at one or more locations within the battery, including within an air electrode, within a material coupled to the air electrode, as a separate film or membrane, within pores of a polymeric separator, or elsewhere.

Abstract: A metal-air battery includes a metal electrode, an air electrode, and at least one of an ionic liquid and a deep eutectic solvent provided within the metal-air battery. The ionic liquid and/or deep eutectic solvent may be provided at one or more locations within the battery, such as in a liquid electrolyte, within a polymeric separator, blended within a polymeric material, within the structure of the air electrode, or elsewhere.
