Research

In Electronic Materials Laboratory, we have designed an inorganic material that generate mobile “protons (H+)” and “hydride ions (H-)” in the crystal lattices, and have developed unique inorganic ionic conductors in which hydrogen redox between H+ and H- proceeds according to the hydrogen chemical potential. Based on these materials, we also create a “solid-state ionic device” that simultaneously conducts electrochemical water splitting and reduction/hydrogenation reaction with electricity derived from renewable energy so as to produce useful chemical compounds from common raw substances such as water and air. Our skills are as follows: inorganic material design using first-principles calculation, precise structural and electronic state analysis using advanced X-ray and neutron beams, device fabrication by solid-state and vacuum processes, and electrochemical evaluations of the device performances.
