Abstract

For the development of new type cell, a study on new electrolyte, $AgI-Ag_8S_3SO_4$ system has been carried out by using electrical conductivity measurement, DTA and X-ray powder diffraction method. From both X-ray powder diffraction and DTA method, it is clearly known that 20mole% $ Ag_8S_3SO_4$-AgI system forms single phase, having monoclinic structure. It is also found that 20mole% $Ag_8S_3SO_4$-AgI system is purely $ Ag^+ $cation conduction from results of conductivity measurement by applying 4-probe method.

새로운 전지의 개발을 위하여$ AgI-Ag_8S_3SO_4$system들을 만들어 이에 대한 전기전도도 측정, 상 연구 및 그 구조를 조사하였다. X-ray powder diffraction method로 20mole% $ Ag_8S_3SO_4$-AgI system의 구조가 단사정계임을 규명하였고 DTA method로 단일상을 이룸을 확인하였다. 4-probe method를 적용시켜 전기전도도를 측정한 결과 20mole% $ Ag_8S_3SO_4$-AgI system이 순수한 $ Ag^+ $이온성 couduct임을 밝힐 수가 있었다.
