| Outline of Final Research Achievements |
We have developed new synthetic, analytical, computational, and informatics methods in the fields of inorganic solid-state materials, enabling the exploration of fast lithium-ion and hydride-ion conductors. We have elucidated that the ionic conductivity within solids and between solids is determined by defect structures ranging from atomic to nanometer scales. Additionally, we have revealed correlations between ionic conductivity and not only electric fields but also stress and light fields, thereby expanding the scientific understanding of ionic conductors.

| Academic Significance and Societal Importance of the Research Achievements |
イオン導電体内およびイオン導電体間をイオンが高速に動きまわるメカニズムは十分に理解されていない．観測の難しさからこれまで着目されていなかった局所的な構造を実測および制御することで，イオン導電体を高機能化できることを実証したことは学術的に意義がある．イオン導電体はエネルギー変換・貯蔵デバイスの基幹材料であり，高機能材料の創出および機構理解は，エネルギー高効率利用や二酸化炭素排出軽減の観点から社会的意義も大きい．
