Embodiment 1
[0094]In this example, first mix yttrium nitrate 5 hydrate, manganese nitrate 6 hydrate, and malic acid in a molar ratio of 1:1:6, then add pure water, and use a rotary ball mill to grind at a speed of 500 rpm for one hour before mixing , so as to prepare a mixture of composite metal oxide materials. Next, the prepared mixture of composite metal oxide materials was allowed to react at a temperature of 250° C. for 30 minutes, then allowed to react at a temperature of 300° C. for 30 minutes, and then reacted at a temperature of 350° C. for one hour. Next, after pulverizing and mixing the mixture of the reaction products, firing at 1000°C for 1 hour to obtain hexagonal YMnO as a composite metal oxide 3 .
[0095] Then, except that the mixture of the reaction product was pulverized and mixed and then fired at 1000°C for one hour, the rest of the conditions were the same as those for making hexagonal YMnO 3 When it is exactly the same, the orthorhombic YMnO as a composite metal o...
Embodiment 2
[0118] In this embodiment, firstly, in the same manner as in Example 1, a hexagonal composite metal oxide (hexagonal YMnO 3 ) and non-hexagonal composite metal oxides (orthorhombic YMnO 3 , orthorhombic YMn 2 o 5 and tetragonal Y 2 mn 2 o 7 ) Sintered body composed of mixed crystals.
[0119] Then, the prepared sintered body and MnO 2 Mix at a mass ratio of 70:10, and use the resulting mixture as an oxygen storage material. The MnO 2 It is a metal oxide that can intercalate or detach lithium ions in electrode reactions.
[0120] Next, in addition to using the sintered body and MnO 2 Except that the mixture was used as the oxygen storage material, the remaining conditions were exactly the same as those in Example 1, and a metal-oxygen battery 1 was obtained.
[0121] Then, discharge was carried out under the same conditions as in Example 1 except that the metal-oxygen battery 1 prepared in this example was used. The relationship between the cell voltage and the disch...
Embodiment 3
[0131] In this example, first mixed hexagonal YMnO 3 and orthorhombic YMn 2 o 5 , except that, in exactly the same manner as in Example 1, a mixture containing a hexagonal composite metal oxide and a non-hexagonal composite metal oxide was prepared.
[0132] Next, a sintered body composed of a hexagonal composite metal oxide and a non-hexagonal composite metal oxide was produced under exactly the same conditions as in Example 1 except that the obtained mixture of multiple composite metal oxides was used.
[0133] Then, for the sintered body obtained in this example, the X-ray diffraction pattern was measured in exactly the same manner as in Example 1. Identify hexagonal YMnO 3 and orthorhombic YMn 2 o 5 Mixed crystals are formed.
[0134] Next, except for using the sintered body prepared in this example, the rest of the conditions are exactly the same as in Example 2, mixing MnO 2 , and the resulting mixture is used as an oxygen storage material.
[0135] Next, in addi...
