Python Supercapacitor Analysis Tool

We have developed a python toolkit for the analysis of supercapacitors. It aims to offer an easy and standardised way to extract useful information from the Galvanostatic Charge Discharge (GCD) curves. This includes the capacitance and equivalent series resistance for each charging/discharging cycle and their evolution with time (Figure 1), the relationship between capacitance and current density (Figure 2), and more. Various built-in options in the library also provides the flexibility suitable for the scientific investigation of supercapacitors. For more information , please visit
