MODELING ELECTRICAL DOUBLE LAYER AND PSEUDOCAPACITIVE PERFORMANCE OF CARBON ELECTRODES

摘要

In order to assess and improve performance of carbon based capacitors, it is important to be able to model and fit experimental data derived from Constant current charge/discharge and Electrochemical Impedance Spectroscopy. Equivalent circuit models such as transmission line modeling are commonly used to study and fit the experimental data of porous electrodes. Another approach is to use porous electrode theory to describe the physical phenomenon at the electrode/electrolyte interfaces.
