Outline of Final Research Achievements

Electronegativity, a measure of the tendency to attract a bonding pair of electrons, is an important index closely related to materials properties. In this study, by expanding the conventional estimation method of electronegativity for elements, we propose new method for complex anions composed of transition metals (Fe, Ni) and non-transition metals (B) with high hydrogen density. The new method enables us to systematically understand the materials properties of various complex hydrides.

Academic Significance and Societal Importance of the Research Achievements

遷移金属や非遷移金属を含む錯体水素化物には、燃料電池や全固体電池など多様なエネルギーデバイス・システムの社会普及を目指す高密度水素貯蔵や高速イオン伝導などの優れたエネルギー関連機能が隠されている。本研究成果により、錯体水素化物の材料物性を体系的に理解することが可能となり、高い潜在性を持ちながらも機能材料としての認識が限定的であった錯体水素化物の学術的・社会的価値を高めることに貢献した。
