| Research Abstract |
In this study, structure and ionic conductivity at nano hetero interfaces are studied. As for AgI/mesoporous Al_2O_3 system, which shows peculiar ionic conduction, it was revealed that AgI confined in nanopores is amorphous and molten Ag ions move in a rigit I-ion framework freely like Ag ion in alpha AgI. For the interface of solid electrolyte and electrochemically active materials, difference of chemical potentials of ions induces change in composition and ionic conductivity.
