NOVELTY - Oxygen adsorption and desorption material, is claimed. The oxygen adsorption and desorption material has pores and/or channel structures for storing oxygen inside. USE - Oxygen adsorption and desorption material is useful for fully enclosed lithium-air battery (claimed). ADVANTAGE - The material has reversible adsorption and desorption ability of oxygen, when the battery is discharged, oxygen is released from the oxygen storage layer and enters the cathode through the isolation layer to react, when the battery is charged, the oxygen generated by the reaction will be absorbed by the oxygen storage layer again through the isolation layer. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) preparing the oxygen absorbing and desorbing material, comprising (a) mixing the oxygen storage material and the binder in an organic solvent, coating the uniformly stirred mixture on the substrate, until the mixture is completely dried, where the mass ratio between the oxygen storage material and the binder is 9:1, 6:1, 5:1, 4:1 or 3:1; (2) fully enclosed lithium-air battery, comprising lithium anode, diaphragm, cathode, isolation layer and oxygen storage layer arranged successively in layers, and the oxygen storage layer is an oxygen adsorption and desorption material. The lithium anode, separator, cathode, separator and oxygen storage layer are all located inside the sealed battery case.
