Galvanostatic Charge–Discharge (GCD) | Battery & Supercapacitor Testing 🔋📈

Galvanostatic Charge–Discharge (GCD) is one of the most important electrochemical techniques used to evaluate the performance of batteries and supercapacitors. In this video, we explain the working principle of GCD, how constant current charging and discharging occurs, and how the voltage–time curve is analyzed. You’ll learn how GCD helps in calculating key parameters such as specific capacitance, charge–discharge capacity, energy density, power density, coulombic efficiency, and internal resistance (IR drop). This method is widely used in electrochemical energy storage research due to its simplicity and reliability. Whether you are a student, researcher, or beginner in electrochemistry, this video will help you understand GCD clearly and effectively.
