Outline of Final Research Achievements

Materials science on hydrides with high-density hydrogen was greatly advanced; by synthesizing new hydrides composed mainly of 3d-Transition-Metals (TMs) for which hydrogen-densification is difficult (so called, the Hydride-Gap), by analyzing and building-up databases on them, and by enhancing their energy-related functions. The typical research outputs are as follows; synthesizing of the novel high-density hydrides composed of complexes with six- to nine-fold hydrogen coordination, clarifying the densification process, and developing as fast-ionic conducting materials for battery device application.
