As discussed in detail in our previous work, it is highly challenging to obtain accurate electrochemical kinetic measurements of LIB AMs at high current densities . Several necessary conditions must be maintained to ensure the accuracy of the measurements and data analysis. First, the AM, electrode, and cell designs must be optimized to eliminate any extraneous resistances or other artifacts in the data. Second, the ohmic resistance must be precisely measured and quantitively accounted for in the data analysis. Third, the condition of stability must be maintained: the kinetics of the system must be time-invariant and cannot change appreciably during or because of the kinetic measurements. Finally, for EIS measurements, the conditions of stationarity and linearity must be maintained to ensure validity of the data analysis. In the following section, it is quantitatively shown how each of these conditions can be satisfactorily met for S3E-CP, LA-GEIS, and O-GEIS measurements by optimizing the measurement methodology.
