| Outline of Final Research Achievements |
Aiming the realization of flexible devices by structural design using nanosheet laminated film, the following results were obtained.
The oxide-nanosheet laminated thin films exhibited very high-speed electrode characteristics, and a flexible property with a small change in conductivity even during bending deformation. By constructing all the electrodes and solid electrolyte with nanosheet laminated thin films, we succeeded in producing proton batteries with flexible storage characteristics that the capacity does not change even during bending deformation. In addition, for the lithium-ion battery, guideline of structure design was obtained in which a battery using a laminated film of small-sized nanosheets as a solid electrolyte shows a large capacity.
