Fitting of Equivalent Circuit for Electrochemical Impedance Spectroscopy data using ZView 4 software

ZView 4.0 is the best option for electrochemistry analysis because, unlike later versions, it allows you to use as much data as you need.
In this video, I install the ZView software and demonstrate the steps to fit the EIS data spectrum using ZView 4.0. With this version, you can create Nyquist, Bode frequency, and Bode-phase plots. Additionally, you can export your fitting results.

Whic Semi circle in double semicircle gives Rb value to calculate ionic conductivity

[@Your_Research_Buddy]

In the case of a double semicircle in a Nyquist plot, the bulk resistance Rb is determined from the high-frequency semicircle, as it corresponds to the material's bulk properties. The low-frequency semicircle usually represents grain boundary or electrode interface contributions.

[@havefaith7850]

Thank you very much. Can you please do this in EIS software

How to determine the resistance from the grain resistance and grain boundary resistance from the Nyquist plot?

[@Your_Research_Buddy]

Thank you for watching. Generally, for materials with grain and grain boundary contributions, the plot typically shows two semicircles: High-frequency semicircle corresponds to grain resistance and this belongs to grain resistance. Low-frequency semicircle corresponds to grain boundary resistance both grain as well as grain boundaryresistance. To fit the data for precision: Use an equivalent circuit model (typically a combination of two 𝑅−𝐶 R−C circuits in series.

Sir, would you be able to create a video to share regarding this so that I can calculate ionic conductivity measurements for my solid electrolyte? To make it clearer for us. Wld really really appreciate! 🥺🙏🙏🙏

Will the old key of version 2013 will work in the new one

[@Your_Research_Buddy]

Probably not. 😊

the value of Rs, Rp and CPE displays the one dialogue box and how to fix the Wo and Rf values..

[@Your_Research_Buddy]

I appreciate your question. You will get Wo and Rf values in the same dialogue box once you add these elements.

i've question, what's a meaning CPE P and CPE T??

[@Your_Research_Buddy]

Thank you for you query. The CPE (constant phase element) is defined by two values, CPE-T and CPE-P. CPE-T, parameter represents the magnitude of the CPE. It is a measure of the capacitance-like behavior of the element. In the context of impedance, it is often referred to as the pseudocapacitance or the capacitance coefficient. while CPE-P, parameter represents the phase angle of the CPE, which indicates how much the behavior of the CPE deviates from that of a pure capacitor. It ranges between 0 and 1, where 1 corresponds to a pure capacitor (ideal capacitor behavior) and 0 corresponds to a pure resistor (ideal resistor behavior). If CPE-P equals 1 than the equation is identical to that of a capacitor. If CPE-P equals 0.5, a 45 degree line is produced on the Complex-Plane graph. I hope this can help.

Hi. Helpful video. However, I am not able to plot for all the input data. It is only plotting for a range of input values. Are you using a full version of the software? Because I think since mine is a demo version I am not able to plot it. Please suggest a solution.

[@Your_Research_Buddy]

Thanks for asking! Have you prepared a data file with (.dat)?

[@mlnsai981]

@@Your_Research_Buddy I prepared with ".txt" file as shown in the video. I am also using the Zview 4 version. Please suggest a solution. It will be really helpful. Thank you :)

@@Your_Research_Buddy Hi, I tried with .dat format as well. It is plotting for only 15 data points as before. Any suggestions? I can share my data file with you if needed. Please suggest.
