Based on mathematical solutions of the impedances of one-dimensional transmission-line models, a variety of models of porous electrodes are made to cope with possible actual cases. In the examined models, ionic resistance in pores, faradaic impedance, and electronic resistance are considered. Numerical calculation of the impedance values of each model revealed the effects of each parameters on the behaviors of the Cole-Cole plots. In addition, effects of additional elements set at the both ends of the transmission-line model, which determine the boundary conditions, were also examined. Finally, possibility to extract the impedance at the interface only by reverse-estimation was investigated. Although this attempt has been achieved, it is also demonstrated that inaccuracies of the assumed parameters might deteriorate the estimated values.
