| Outline of Final Research Achievements |
In this work, several novel ionic conductors and related novel materials were successfully discovered by exploration of new ionic conductors containing relatively large ions, such as Cs. In particular, the discovery of oxide-ion-conducting oxychlorides is a very innovative achievement. For the discovered materials, relationships between structures and properties (ionic conductivity) were investigated using X-ray and neutron diffraction techniques. The established structure science of the novel ionic conductors provide new guideline for exploration of next ionic conductors.
