| Outline of Final Research Achievements |
Electrode materials that have high stability against anodic polarization and high activity toward oxygen reduction reaction (discharge reaction) and oxygen evolution reaction (charge reaction) are required for improving the performance of metal-air batteries. In this study, we focused on graphene as an electrode material of metal-air batteries. The mechanochemical method was investigated as the synthesis method of graphene. As the result, multi-layered graphenes were successfully obtained by mechanochemical reaction using planetary ball mills. The graphene synthesized by the mechanochemical reaction showed higher oxygen reduction and evolution activity than the chemically exfoliated graphene. The oxygen evolution activity of the graphene synthesized by the mechanochemical reaction was improved by doping nitrogen and sulfur. Moreover, it was found that the graphene synthesized by the mechanochemical reaction has high activity toward the glucose oxidation.
