Abstract
There is provided a metal oxygen battery which uses an oxygen-storing material containing YMnOas a positive electrode material, and can reduce the discharge overpotential. The metal oxygen batteryhas a positive electrodeto which oxygen is applied as an active substance, a negative electrodeto which metallic lithium is applied as an active substance, and an electrolyte layerinterposed between the positive electrodeand the negative electrode. The positive electrodecontains, as an oxygen-storing material, a composite metal oxide obtained by crushing and mixing a yttrium salt, a manganese salt and an organic acid, primarily calcining the mixture, and thereafter, adding a zirconium salt to the obtained primarily calcined material, and secondarily calcining the mixture, the composite metal oxide containing YMnOand ZrO.
