Hi jketter, You are absolutely right with your suggestion but I don't know any person who can I interact about this kind of discussions. Therefore, I need to learn myself as much as I can. Firstly, I want to explain what I'm looking for and what I already have. My working electrode is TiO2-Deposited FTO/Glass (thin film). I use LiClO4-PC aqueous solution as an electrolyte. The method is discussed in several papers (doi: 10.1016/0167-2738(86)90214-6). Upon Li+ intercalation due to change in structure TiO2 expected to change a color (from a transparent to grey). However, there is no discernible change in the color that can human eye recognize in my analysis. As a result, I have doubt about the reactions kinetics. So my questions are, as follows. 1) Does seeing a peak in CV curve guarantees that some redox reactions is happening? 2) I've attached a picture of CV curves for various scan rates. Do you agree that it is a quasi reversible system (also discussed in here:https://www.researchgate.net/post/How_to_interpret_CV_redox_peaks_and_is_it_possible_run_a_Chronoamperometry_simulation_from_existing_CV_data) 3) Since current is proportional to scan rate what is the correct way to calculate inserted charges (Qa and Qc -> Integration in Gamry) 4) After a lot of try, I found going to further from -1.7V broke my working electrode. And also, going to away from +1.9V. Can I consider this, as my limitations? 5) What does max current means in CV measurement? Does changing the value effects the shape of the curve? By the way, by simulating I meant to be able to convert CV curve to Current-Time curve since all parameters are known. İn example: In attached image I have CV's for various scan rates. I also now potential differences. So I can obtain the required time for a full cycle and the integration gives me the total charge inserted and extracted from the electrode. Of course, I will not be sure if this value will reflect the truth until I'll sure where/when does redox reactions happening. I'm looking for a guidance rather than answer to my questions. I know that there is a lot, and it is not possible to cover all of them in here. Waiting for your suggestions. Thank your for your interest/help. Question.tiff

I'm using Gamry Potentiometer for taking CV measurements for finding the appropriate voltage values for oxidation/reduction peaks and Echem Analyst for analyzing. CV measurements has performed on liquid electrolyte in order to find if working electrode accept Li ions. My question is about interpreting the results. How can I interpret if potential difference equal or below 1V has no oxidation or reduction peak (or has only one of them) while potential sweep between -2V to 2V bring good results but if I change it to 1 to -3 no reduction peak again. Moreover, going to negative values has a bad consequences such broke the working electrode. What does it mean going to negative values? That was my first question, my second question is: Is it possible perform Chronoamperometry measurements (in other word, simulate) by using existing CV measurements via Echem analyst script editor?
