制备了含I-的固体电解质薄膜 ,用阻抗谱法测量了样品的I-电导率 ,分析了样品的频响特性曲线 ,用Wagner直流极化法测量了样品的电子电导。实验发现 ,此阴离子导体几乎和相应的含Na+有相同的离子电导率 ,且随着碘含量的增加 ,电导率增大。离子电导实验结果表明 ,在此阴离子导体中 ,电子电导占总电导率的 9% ,而空穴的电导率比电子电导率小 1～ 2个数量级。 The I-containing solid electrolyte membrane was prepared, the I-conductivity of the sample was measured by impedance spectroscopy, the frequency response curve of the sample was analyzed, and the electronic conductivity of the sample was measured by Wagner DC polarization method. The experiment found that this anion conductor almost has the same ion conductivity as the corresponding Na +, and with the increase of iodine content, the conductivity increases. The results of ion conductance experiments show that in this anion conductor, the electron conductance accounts for 9% of the total conductivity, while the hole conductivity is 1-2 orders of magnitude smaller than the electron conductivity.
