研究了GeS2‐Ga2S3‐Li2S‐LiI玻璃粉末在单轴压缩条件下的界面电阻和界面电容。通过改变压力，观察到界面电阻和电容的几何尺寸发生了显著变化。假设界面电阻和电容来源于粉末颗粒之间的接触区域，建立了一个能很好地描述界面电阻和电容几何尺寸变化的定量模型。本研究强调，改善颗粒间的接触是降低高导电性硫化物固体电解质粉末制成的粉末型离子导电器件界面电阻的重要方法之一。
The interfacial resistance and capacitance in pellets made from GeS2‐Ga2S3‐Li2S‐LiI glass powder are studied under uniaxial compression. By varying the pressure, remarkable change in the geometric dimension of the interfacial resistance and capacitance is observed. Assuming that the interfacial resistance and capacitance arise from the contact region between the powder particles, a quantitative model is established that well describes the geometric dimension change in the interfacial resistance and capacitance. This work emphasizes that ameliorating the contact between the particles is one of the most important methods to reduce the interfacial resistance in the powder‐type ionic‐conduction devices made from highly‐conductive sulfide solid electrolyte powders.
