A metal-oxygen cell capable of improving cycle performance is provided. The metal-oxygen cellincludes a positive electrodethat contains an oxygen storage material and uses oxygen as an active material, a negative electrodethat uses a metal as an active material, and an electrolyte layersandwiched between the positive electrodeand the negative electrodeand containing an electrolyte solution, effecting cell reactions of the positive electrodeon a surface of the oxygen storage material. The positive electrodecontains a conductive polymer that is capable of suppressing permeation of oxygen and conducting metal ions and covers at least a part of the surface of the oxygen storage material.

Metal-oxygen cell

There is provided a metal oxygen battery which is capable of obtaining superior batter capacity when starting use from charging. In the metal oxygen batteryincluding a positive electrode, which includes an oxygen-storing material and lithium oxide, and uses oxygen as an active substance, a negative electrodecapable of absorbing and discharging lithium ions, and an electrolyte layerinterposed between the positive electrodeand the negative electrode, in which the positive electrode, the negative electrode, and the electrolyte layerare hermetically accommodated in a case, the oxygen-storing material has an oxygen amount stored at a start of charge time diluted.
