Structure and Ionic Conduction of Solid Electrolyte Confined in Nanopores

本研究研究了纳米异质界面的结构和离子电导率。对于表现出特殊离子导电性的AgI/介孔Al_2O_3体系，研究发现，被限制在纳米孔中的AgI是无定形的，熔融的Ag离子像在α AgI中的Ag离子一样，在正确的i离子框架中自由移动。对于固体电解质和电化学活性材料的界面，离子化学势的不同引起了离子组成和电导率的变化。

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.
