Outline of Final Research Achievements

Development of millisecond-order structural observation technique was performed using most powerful pulsed neutron source of the Materials and Life Science Experimental Facility, the Japan Proton Accelerator Research Complex (J-PARC/MLF), and a in-situ cell was prepared for structural investigations of rechargeable batteries in operand. The conduction pathways of lithium ions in solids were predicted and visualized by combining reverse Monte Carlo (RMC) modeling and the bond valence sum (BVS) approach using neutron diffraction data. Dynamics of lithium ions in Li7P3S11 glass-ceramic superionic conductor was studied using quasi-elastic neutron scattering.
