چکیده:

Mathematical modeling can be used to improve understanding of the structures and processes in supercapacitors. There are a few models for pseudocapacitors compared to electrochemical double layer supercapacitors. Lin et al [1] developed a new model which considers both double layer charging and Faradaic process as the origin of the psudocapacitity. To finding the important parameters and their effects on the performance of a pseudocapacitor, the authors analyzed their model theoretically [2]. Recently we developed a new model for the performance of mixed oxide pseudocapacitor [3, 4] too. All of these model don’t use of structural details of the active materials. In this work, we make a model for impedance response of pseudocapacitors because both structural and electrochemical properties are important in the impedance response
