1. A method of preparing a lithium-oxygen battery, the method comprising:
providing a lithium anode, an air cathode comprising reduced graphene oxide, and an electrolyte comprising an ether solvent, benzonitrile, and a lithium salt forming an electrochemical cell; and
cycling the electrochemical cell to form a coating of red poly(benzonitrile) on at least a portion of the lithium anode.
