Outline of Final Research Achievements

Stable electrode materials under oxygen evolution reaction (charging reaction of metal air battery) was investigated for the construction of metal-air secondary batteries. It was found that Niobium doped-TiO2 (Nb-TiO2) is stable under oxygen evolution reaction. LaNi0.5Mn0.5O3 addition was effective for improving both the oxygen reduction reaction activity and oxygen evolution reaction activity of Nb-TIO2. It was also found that graphene is stable for under oxygen evolution reaction. NiCo2O4 was effective for improving the oxygen evolution reaction activity of Nb-TiO2.
