| Research Abstract |
We have focused on the electrode function of insulating materials which had been believed inactive. Some compounds with high activity were discovered during the project, of which structure was also determined. Atomic-scale anisotropic lithium diffusion and subsequent clustering, together with their kinetics, were experimentally elucidated. Thermodynamic approach was made to understand the size-dependency of these phenomena.
