Electrode potential (E) plotted against time (t) during a ‘current on’ step (I = 20 mA g−1) and a ‘current off’ step (I = 0) of the modified GITT program used in this work for the comparison of the results from the GITT, ICI method and EIS. Note that the long rest period is not necessary for the ICI method. It is done in this manner here for the comparison between the three methods.
