Abstract
A lithium-air electrochemical cell is provided. The battery comprises: an anode compartment; a cathode compartment; and a lithium ion conductive membrane separating the anode compartment from the cathode compartment. The anode compartment comprises an anode having lithium, a lithium alloy or a porous material capable of adsorption and release of lithium and a lithium ion electrolyte, while the cathode compartment comprises an air electrode, an ionic liquid capable of supporting the reduction of oxygen and a dissolved concentration of potassium superoxide. A lithium ion concentration in the cathode compartment is low in comparison to the concentration of potassium ion.
