Figure 4
Results for 2 Ω interrupted discharge; each row contains a discharge curve (with the time of the tomography and diffraction measurements indicated by arrows), a reconstructed tomography slice through the region of interest and the corresponding spatially resolved diffraction patterns at different radial distances from the current collector. The third column is for the anode [transformation of Zn (overlapping peaks 110 and 103) to ZnO (peak 112)] and the fourth column is for the cathode [transformation of MnO2 (peak 100) to MnOOH (peak 210)]. The cathode reaction is observed as a peak shift because the materials form a continuous solid solution (Gallaway et al., 2015). |
