LITHIUM-AIR ELECTROCHEMICAL CELL, BATTERY COMPRISING LITHIUM-AIR ELECTROCHEMICAL CELL, AND VEHICLE COMPRISING SAID BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a lithium-air electrochemical cell.SOLUTION: A 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 or a lithium alloy as active metal, and a lithium ion electrolyte, while the cathode compartment comprises an air electrode and an ionic liquid capable of supporting the reduction of oxygen. A lithium ion concentration in the cathode compartment is such that the lithium ion concentration is greatest at the lithium ion selective membrane and lowest at the cathode.SELECTED DRAWING: Figure 1
