Question

Many use Electrochemical Impedance Spectroscopy (EIS) to measure the diffusion coefficient for Li-ions in intercalation based cathodes and anodes.

Yet, we also described both voltammetric and chronoamperometric methods. Please discuss in detail the advantages and disadvantages of these three methods (EIS, Voltammetry and Chronoamperometry).

Which method do you consider the best method to quantify diffusion coefficients?
