• Our focus is on the development of solid-state-ionics materials to be used for a variety of energy conversion systems. To further improve the performance of fuel cells and lithium batteries, novel ionic conductors and mixed conductors with high ionic conductivity and chemical stability are highly demanded. We have been developing such the materials based on defect chemistry and thermodynamics of ceramics, and trying to apply those materials to actual energy conversion devices.

To date, a hydrogen production system utilizing oxygen permeable membranes and an all-solid-state battery have been prepared.
