NOVELTY - A fast-charging lithium-air battery comprises an anode, a diaphragm, an electrolyte obtained by dissolving a lithium salt in ether-based organic solvent including a fluorine-containing ether compound, and a cathode. The anode is grown in-situ with metal-lithium oxide transition metal-doped discharge product (I) in the form of a nanosheet array, where metal is transition metal including zinc, nickel, cobalt, iron and/or manganese, preferably cobalt. USE - Fast-charging lithium-air battery. ADVANTAGE - The fast-charging lithium-air battery: has self-catalytic activity; can be prepared by a method, which is simple; adopts discharge product, which greatly reduces the over-potential of battery during charging and discharging, and improves stability of battery; and uses catalytically active material, which is transition metal-doped lithium peroxide produced during charging and discharging process of the battery, thus eliminating the need for separate preparation, and can be prepared by using commercial low-cost raw materials in an industrial manner. DETAILED DESCRIPTION - A fast-charging lithium-air battery comprises an anode, a diaphragm, an electrolyte obtained by dissolving a lithium salt in ether-based organic solvent including a fluorine-containing ether compound, and a cathode. The anode is grown in-situ with metal-lithium oxide transition metal-doped discharge product of formula: M'xLiyO2 (I) in the form of a nanosheet array, where M' is transition metal including zinc, nickel, cobalt, iron and/or manganese, preferably cobalt, x is greater than 0 to less than or equal to 0.1, preferably greater than 0 to less than or equal 0.05, and y is 0.90 to less than 1, preferably 0.95 to less than 1. An INDEPENDENT CLAIM is included for preparation of the fast-charging lithium-air battery.
