Outline of Final Research Achievements

Novel ion conducting materials that can be applied to energy devices were developed. In addition to classical material search, new direction for material exploration using theoretical science and information science was examined. Hydride ion conductors, which are new ionic conduction species, were developed and demonstrated applicability as an electrolyte for all-solid-state energy devices. For the nano interfacial analysis using the quantum beam, the clear relationship between the nanometer-scale electrochemical interfacial structure and the device performance was revealed. The solid electrolytes in which lithium ions and oxide ions diffuse were developed by exploration based on the known crystal structure. Furthermore, a novel material search method for ion conductors with new composition and new structure using the information science was conducted. The problems to solved and possibility of the novel method were proposed.
