Outline of Final Research Achievements

In the present study, using an environmental high-voltage electron microscope, (1)lithium-related materials were studied under non-exposue-in-air conditions, (2)In-situ observations were performed with heating, applied voltages and various atomspheres in order to study degradation processes of the materials, and (3)various kinds of battery-related compounds were studied by STEM-electron energy loss spectroscopy for analysis of elemental distribution, and nano-probe electron diffraction mapping for study of local strain around interfaces of multi-layered structures.
