Calculation of Specific Capacitance of a Supercapacitor from Cyclic Voltammetry data

Estimation of Specific Capacitance of a Supercapacitor Electrode Material from the Cyclic Voltammetric Curve (I vs. E Curve) by using Origin computer program.

Formula to calculate Specific Capacitance: Cs = A / (2. m. ν. dV)

Cs – Specific capacitance (F/g) .
A – Area under the I vs. E curve (AV)
m – Mass of the electrode material (g)
ν – Scan rate (V/s)
dV – Potential window (difference in potential)
