Abstract
A metal-air battery comprising an emulsified or dispersed aqueous/ionic liquid two phase electrolyte system is provided. The two phase electrolyte system contains an aqueous phase and an ionic liquid phase wherein an amount of water exceeds the aqueous solubility of the ionic liquid. In one embodiment the metal-air battery is a lithium-air battery.
