Supercapacitor model with ion transport | Galvanostatic | porous media | COMSOL 5.6

[@PrakashKumar-t7i]

can we perform cyclic voltammetry simulation on li-ion battery? if yes then how?

[@simulationbyhm5194]

check out my other videos I did one on cyclic voltammetry as well

[@xawang696]

Many thanks for the video, I am a beginner at COMSOL and have some questions. Firstly, if I consider faraday reactions, do I just need to enable "electrode reactions" and add parameters? Secondly, what's the difference in the boundary condition setting if I use a normal electrode instead of a porous electrode? Finally，I want to apply cyclic voltammetry by adding "electrode surface", why can't I select the boundary? Or do I have to do cyclic voltammetry in some other way? Looking forward to your reply.

[@simulationbyhm5194]

electrode reactions is not much of help instead try with simple solid electrode and as for modelling reaction on the surface which penetrates into the electrodes apply a boundary condition for flux that allows for Li ion or other such intercalation ion to go in and out of electrode during charging and charging. As for cyclic voltammetry try apply electroc potential at one end of the capacitor instead of current density and control the voltage variation using interpolations function for the profile of voltage you want to input

SIr, I have electrodialysis model with ultrafiltration, I design the model but there is issue. Can you please help me?

[@IrfanAli-bs8nm]

I will pay for it

Hello sir, thank you for your informative video, is it possible to do this work in ANSYS Fluent?

[@simulationbyhm5194]

I would be honest, i have no idea whether it is possible in ANSYS or not. but i think if you are good with ansys COMSOL takes a month to get used to it after ansys.

Hi, can we calculate capacitance of this model?

[@simulationbyhm5194]

You can use a simple formula like "capacitance = Time integration of (current/Voltage)" at the boundary where the current was applied in the simulation his should give you the capacitance.

[@aqschaudhry1218]

@@simulationbyhm5194 it gives units of 'S' but capacitance has units 'F'

Many thanks for the video, could you please show us how to model a supercapacitors with faradaic redox reaction

[@simulationbyhm5194]

Your welcome Noumi Rihem. For the faradaic redox reactions @Porous electrode@ have a subnode for reactions you can use that. Actually, I am swamped with work at the moment for next few weeks due to the deadline with a project I have. So I might not be able to to it right now. Extremely sorry

Sir, It is very good video simulation in comsol. I am beginner in Comsol and I need to solve work. Would you like share your mph.file?

[@simulationbyhm5194]

Sure, here is the link to google drive. drive.google.com/file/d/1uLRdoeWNtVyO1vuTaHcVhzhiZCqAN001/view?usp=sharing

[@herirustamaji5620]

Thank you very much Sir. It is very valuable for me. I wait the other video from you about supercapacitor (if posible it is about thermal modelling of supercapacitor).

[@herirustamaji5620]

always success for your channel.
