Outline of Final Research Achievements

The purpose of this research is to rise research and development of all-solid-state lithium-ion batteries to the unprecedented level based on deep understandings about electrode/electrolyte interface phenomena. To this end, I adopted hydrides as solid electrolytes in order to improve both Li ionic conductivity and interface adhesion. In addition, I developed high-quality thin films of Li-ion conductive hydrides that enables investigation of detailed interface phenomena using excellent interface design ability of thin films. The results of this study opened the way for constructing interface design direction and development of high-performance all-solid-state lithium-ion batteries.
