I did the CV analysis of my sample (CNT-MoS2 hybrid) at small scan rates (0.1-1 mV/sec). However, my results show no peaks even at the lowest scan rates, and in order to utilize the Dunn's relation and Trasatti method, i need to pick up a current and respective voltage at every sweep.
Which current value should i consider if there is no anodic and cathodic peaks in my result?
Pranjala,
In this case you can pick the current at the potential where the current increases linearly with the scan rate. Avoid choosing the currents near the upper and lower boundaries of your potential window.
