Usually, EIS measurements are performed in 2 steps: a stabilization step followed by an acquisition step. The first is necessary in order to ensure that the impedance is determined when the system has reached its stationary state. In this work, a theoretical framework is proposed for estimating the required stabilization time for EIS measurements. Here, it was applied to the simplest case: the simplified Randles cell. In order to calculate the required stabilization time for performing EIS

... rements, a theoretical dynamic model of a Randles cell under galvanostatic sinusoidal perturbation was developed. The proposed model can be used to estimate, from a theoretical point of view, the required stabilization time for performing EIS measurements in a Randles-like system. Even though, this work focuses on the simplest case, the developed theoretical framework can be applied to any system, however complex it may be.
