CV Data Analysis through OriginLab - Calculation of Specific Capacitance - 17

Cyclic Voltammetry (CV) is among the various techniques, used to study the electrochemical properties of nanomaterials. Those materials which possess good electrochemical properties are used in supercapacitors and rechargeable batteries. The electrochemical factor which decided whether the material could be used in energy storage devices or not is the specific capacitance. In this video, I have shown a detailed method for the calculation of specific capacitance from CV data through OriginLab software.

Good evening sir..How can I get specific capacity from cyclic voltametery curve?

[@ruchindagooneratne7684]

Love all the vids! I do have a question with regard to the final equation. Since the absolute area was used, shouldn't eq (6) be used instead of (10)? Meaning, that the specific capacitance doesnt need to be divided by 2? Thanks!

really appreciate your efforts. Could I ask how could you calculate the specific capacitance from three electrode system in GCD and CV. thanks in advance

[@kirannargatti]

Really helpful and great explanation. But one thing is not clear, in case of 3 electrode system if we consider absolute area from origin software, then the capacitance equation will be A/2mk(v2-v1) or A/mk(v2-v1)? and in given example, final answer 33.89 is correct or it should be 67.78?

[@nanoworld6122]

This was for discharching of capacitor.

[@aadilkhan9196]

A.O.A Really good one and nicely explained.But I have an objection. I hope you will try to resolve it. During surface area calculation we should use area within the CV loop , actually you divide the equation by 2 to get that area (area within the CV loop) .But in example solution you have determined that area (within the loop) then you should not divide the equatiuon by 2.

[@nanoworld6122]

This formula is used for both, i.e. 2 electrodes as well as 3 electrodes electrochemical work station data. In the case of the 2 electrode system, if we considered the electrodes are symmetric (ideally) then we should not divide it by 2 ( we considered it is already divided). I performed my CV characterization in 3 electrodes electrochemical work station ( As I mention it in my video), that's why I divide it by 2.

What does the capacitance during discharge exactly means? Little confused here.. isn't it the device capacitance? Why need to subtract it from charging capacitance to get the device capacitance?

i have one query. you have area in (AV), mass in (g), scan rate in (mV/s), potential window in (V) so how do you got capacitance in F/g. I think area should be in (mAV)

Please re-watch this video, and note everything in your note book and then re-think about it.

@@nanoworld6122 yes sir, i got it now, you have converted scan rate into V/s during calculation. Thank you for replying sir.

yes, the potential is in Volts and the scan rate in in mV

Don't you think that the unit of scan rate should also be V/s instead of mV/s that you are using while calculating Cp in excel sheet. Since 1 F is equal to 1 A.s/V

[@nanoworld6122]

I think you did not watch it carefully. When putting formula, I multiply it with 10^-3. This means I already used V/s for the rate. Please re-watch
