Dear friend Niranjan Pandit

The cyclic voltammetry (CV) and galvanostatic charge-discharge (GCD) techniques are commonly used to estimate the capacitance of a supercapacitor. The capacitance values estimated from these two techniques may differ due to their different measurement principles. CV measures the current response to a voltage sweep, while GCD measures the voltage response to a constant current.

To make a comparison between the estimated capacitance values from these two techniques, you can follow the steps below:

It is important to note that both CV and GCD are useful techniques for estimating the capacitance of a supercapacitor, and a comparison of the estimated capacitance values can provide valuable insights into the behavior of the supercapacitor.
