| Outline of Final Research Achievements |
Surface modification of cathode materials, such as surface coating with metal oxide thin films, is one of the promising methods to improve the performance of all-solid-state batteries. In order to understand the effects of the modification on electrochemical property, it is of importance to obtain detailed structural information in the modified region at the atomic scale. In the present study, we investigated the microstructures and thermal stability of Li-Ti-P-O amorphous thin films by transmission electron microscopy in combination with nanobeam electron diffraction. As a result, we found the thermally induced structural change related to the development of medium range order in the amorphous thin films.
