| Outline of Final Research Achievements |
Dramatic progresses in the performance of rechargeable batteries are necessary to fulfill various demands for the commodification of electric vehicles. All-solid-state sodium batteries with excellent safety have attracted much attention as one of candidates of post-lithium ion batteries because of great abundance and low cost of sodium. Thus, in this work, we studied three-dimensional structures for (Na2S)x(P2S5)100-x glasses (x=50, 60, 66.7, 70) and Na3PS4 metastable crystal by taking advantage of the reverse Monte Carlo modeling based on the neutron and X-ray diffraction data in order to understand relations between the structure and ionic conductivity.
