Major research activity
We contribute to solve environmental and energy problems for building of a sustainable society by developing new energy-related materials. The main subject is the developments of “high-density hydrogen storage materials” for fuel cell application and “solid-state ion-conducting materials” applicable to solid electrolytes for next generation rechargeable batteries. We explore solid-state materials composed of light-weight metals which can store and release hydrogen reversibly at moderate temperatures and pressures with fast kinetics on the former subject. We also develop novel solid-state hydrides in which Li and Na ions can hop easily, as if they move in liquids, at near or below ambient temperature on the latter subject.
