SIMPLIFY AND RESOLUTION OF IMPEDANCE MODEL FOR SYMMETRIC CELLS

从测量电解池的电化学边界条件出发，对Ｊ．Ｒ．Ｍａｃｄｏｎｌｄ关于对称池的电化学交流阻抗谱（ＥＩＳ）精确解进行了分类化简，给出了不同边界条件下的理想阻抗谱的近似简化关系式、对应等效电路以及各种电路元件与材料性能参数的关系式．由于此模型的通常性，可用来处理半导体、绝缘体、液体、固体电解质、熔融盐及导电聚合物阻抗频谱的实验数据．用此化简模型，以新型原位电化学复合的干态苯胺／聚硫橡胶膜的电化学阻抗数据处理为例，介绍了对称池电化学阻抗数据的处理方法．

In this article simplified classify the symmetric cell EIS accurate solution of J.R. Macdonald by measuring the electrochemical border condition of electrolytic cell, and gave the approximate simplified relation of the ideal impedance spectra, the corresponding equivalent circuits and the relation between various circuit component and the material performance parameter. Because of the common performance of this model, it could be used to handle the experiment data of impedance for semiconductor, insulator, liquid, solid electrolyte, melt salt and conducting polymer. Herein introduced the electrochemical data treatment of cell of cell of symmetry by the simplified model, for example. The electrochemical impedance data treatment of in_situ electrochemical composite“dry” PAn/TR film.
