Analysis of electrochemical parameters for activated carbon supercapacitor

This project investigates the correlation between the cyclic voltammetry (CV), galvanostatic charge-discharge (GCD), and electrochemical impedance spectroscopy (EIS) tests, which are the most common tests done to evaluate the performance of supercapacitor. The main contribution of this work is to st...
