The search of the oxides that function as electrodes in metal-oxygen batteries was performed. Since oxygen atoms in a metal oxide instead of gaseous oxygen molecules in air can be used as active materials if the metal oxide allows insertion or extraction of oxygen atoms, various oxides were investigated in terms of oxygen insertion and extraction. As a result, it was found that a few iron-based and a nickel-based oxides with perovskite-related structures allow reversible oxygen extraction or insertion. By using these materials, a new type battery in which oxygen atoms were shuttled between a cathode and an anode electrode via an aqueous alkaline electrolyte was constructed. Further another new type battery that was composed of the oxide allowing oxygen extraction for a cathode, a metal, such as Li and Na, for an anode, and an organic electrolyte was demonstrated.

对金属氧电池中用作电极的氧化物进行了研究。由于如果金属氧化物允许氧原子的插入或提取，则金属氧化物中的氧原子可以代替空气中的气态氧分子用作活性材料，因此从氧插入和提取的角度研究了各种氧化物。结果发现，一些具有钙钛矿相关结构的铁基和镍基氧化物允许可逆的氧提取或插入。通过使用这些材料，构建了一种新型电池，其中氧原子经由水性碱性电解质在阴极和阳极电极之间穿梭。此外，还展示了另一种新型电池，其由允许氧提取的氧化物作为阴极、金属如Li和Na作为阳极以及有机电解质组成。
