Outline of Final Research Achievements

The element-selective structural analysis methods were used to characterize the local structures in several phosphate compounds with the NASICON-type structure. They are promising materials for lithium ion batteries, as they reveal superior charge-discharge characteristics. The chemical state in Li2NaV2(PO4)3 samples of a candidate cathode during the charge-discharge was analyzed by using X-ray absorption spectroscopy. X-ray anomalous scattering was used to analyze the middle-range order structure in NASICON-type glass-ceramics, which are utilized as electrolytes in solid state batteries. Influences of foreign elements on the local structure around aluminum and phosphorus in these samples were also analyzed by NMR. These results were discussed coupled with their electrochemical properties.
