Abstract
An electrochemical device includes a lithium anode having a red poly(benzonitrile) coating covering at least a portion of the anode; a separator and an air cathode comprising reduced graphene oxide over gas diffusion layer; and an electrolyte comprising an ether solvent, benzonitrile, and a lithium salt.
Claims3
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.
