| Outline of Final Research Achievements |
In this study, ultrasmall MgMn2O4 spinel nanoparticles were synthesized via wet-process such as alcohol-reduction process and hot-injection process. The obtained MgMn2O4 nanoparticles exhibited high-rate cathode performances for Mg secondary batteries operated at room temperature.

| Academic Significance and Societal Importance of the Research Achievements |
マグネシウム二次電池正極はマグネシウムイオンの小さい固体内拡散係数を原因とする低い出力密度が課題であり、実用化には拡散速度を上げるために高温作動が必須であった。本研究で合成された材料を正極に用いることで、低い出力特性を改善、マグネシウム二次電池の室温動作が可能となった。本研究成果によりマグネシウム二次電池の実用化に向け大きく進展したと言える。
