| Outline of Final Research Achievements |
In this study, we performed synchrotron X-ray diffraction (SXRD) and time-of-flight neutron diffraction (TOF-ND) analyses on (Li2S)x(P2S5)100-x glasses (x = 50, 60, and 70), Li7P3S11 glass-ceramic and Li3xLa2/3-xTiO3 crystal and succeeded in clearly visualizing three-dimensional structure and the predicted conduction pathways of the lithium ions at RT by combining reverse Monte Carlo (RMC) modeling and the Bond Valence Sum (BVS) method. The conduction pathways of the lithium ions could be briefly classified into two types: lithium ‘stable’ and ‘metastable’ regions. It was found that a significant relationship exists between the topology of the conduction pathways of the lithium ions and the activation energy of the electrical conduction.
