Ion transfer at interfaces between silver ion conductive solids

离子转移在电极和电极之间的电子转移中的添加物对传感器、电池和其他元件起着重要的作用。电子转移在两个不同的固体接口之间进行了良好的调查，作为半导体的pn接头的典型示例。离子转移也被做了很好的研究，用于液体-液体界面。However，在两种不同固体之间的界面的情况下，有几项关于在界面上传输的研究。在这项工作中，离子转移对界面已经被聚焦，而银离子操纵固体之间的离子转移被调查。Following are the summary of this work.1） Silver ion transfer bet\-AgI and AgCF_D23_ Resistance for the transfer from-AgI to AgCF-D2SO-D23 was found to be larger than that for the transfer from AgCF-D23-PEO to-AgI.2） Relaxation of open circuit voltage was measured for the cells of Ag/-AgI/AgCF-D23-D2SO-D23-D2/Ag。当从AgCF-D23-D2 SO-D2-PEO到α-AgI的界面时，放松时间更快，与时间测量结果的结果是很好的协议。

Ion transfer in addition to electron transfer at interfaces between electrode and electrolyte plays an important role for sensors, batteries, and so on. Electron transfer at interfaces between two different solid has been well-investigated, for typical examples of pn junctions of semi-conductors. Ion transfer has been also well-studied for liquid-liquid interfaces. However, in the case of interfaces between two different solids, there have been few studies on ion transfer at the interfaces. In this work, impedance for the ionic transfer at interfaces has been focused, and ionic transfer between silver ion conductive solids was investigated. Following are the summary of this work.1) Silver ion transfer between α-AgI and AgCFィイD23ィエD2SOィイD23ィエD2 dispersed polyethylene oxide(AgCFィイD23ィエD2SOィイD23ィエD2-PEO)was studied by chronoamperometry. Resistance for the silver ion transfer from α-AgI to AgCFィイD23ィエD2SOィイD23ィエD2 was found to be larger than that for the transfer from AgCFィイD23ィエD2SOィイD23ィエD2-PEO to α-AgI.2) Relaxation of open circuit voltage was measured for the cells of Ag/α-AgI/AgCFィイD23ィエD2SOィイD23ィエD2/Ag. Relaxation time was faster when silver ion transfers at interfaces from AgCFィイD23ィエD2SOィイD23ィエD2-PEO to α-AgI, which is in good agreement with the results of chronoamperometry.
