In case of Galvanostat charge-discharge, the discharging time used to evaluate the specific capacitance using following relation: C=I*t/m*dV. But when it comes to capacity, the area under the discharge curve is more reliable instead of discharging time. I want to know how the area will be evaluated in discharging curve? Here I am attaching the CD curve (origin file as well as Tiff file).
Based on the capacity, is there any change in energy density formula?
I have used the energy density formula: E=C*V2/2*3.6
It is my humble request to the researchers community, kindly drop your valuable suggestions? Thank you
It appears that you want a numerical integration algorithm. I like Gaussian Quadrature or Romberg integration my self. You might look at:

For a very good low cost solution. All info you need is included. Best, D. Booth
