a Evolution of the impedance during stripping for the LiHP|LPSCl|LiHP sample showing all cycles in Bode representation (phase angle Θ versus relaxation time τ) in the upper part of the plot and selected cycles in Nyquist representation in the lower part of the plot. The characteristic frequency of the semicircle is marked with a filled circle. b Resulting distribution of relaxation time curves of the acquired data in (a). As shown in the small insert, the area below the function γ(τ) is the total resistance R for a process at a certain relaxation time τ. c Contour plots for the different samples, as marked with the heading, from Fig. 4 during stripping. The arrows highlight different interfacial contributions during stripping.
