Outline of Final Research Achievements

This study focuses on physical solid-state accumulators composed of amorphous alumina, and examines the fabrication method of the accumulator ribbons, elucidation of the accumulator mechanism, and fabrication of laminate structures. The results of this study provide knowledge on the dimensions and shapes of nano-convexity for optimizing the energy storage performance, and a fabrication method using an anodic oxidation method. The research also clarified that the energy storage phenomenon is caused by the formation of AlO6 clusters by anodic oxidation, and found that isolated electrons appear in the vicinity of defects between O atoms and adjacent Al atoms, which induce a positive charge by electrostatic induction and generate a mechanism for adsorbing electrons. Furthermore, the paper provides useful knowledge on electrode fabrication methods such as the sputtering method for stacking capacitors.

Academic Significance and Societal Importance of the Research Achievements

再生可能エネルギーの増大が緊急の課題であるものの,その開発のボトルネックが相当容量の蓄電システムが未だ構築されていないことである.従来のリチウムイオン2次電池等の蓄電体は,その大きな原子質量のため応答性は低くかつ耐電圧も4 Vまでである.また電解質に溶液を使用しているため,液漏れに起因する事故が発生するなど,安全・安心の観点からも課題がある.本研究の成果は,化学的イオン移動の原理から脱却し,物理的な電子の吸着・脱着に基づく電子自体の直接移動・貯蔵を利用した固体蓄電体を開発した点にある.これにより,蓄電体の耐電圧性,応答速度,電解質の液漏れなどの従来の蓄電池の課題を克服する方法を提供した.
