Results for 2 Ω continuous discharge; each row (A, B, C or D) represents a reconstructed tomography slice through the region of interest and the corresponding spatially resolved diffraction patterns at different radial distances from the current collector at one time point on the discharge curve at the top of the image. Stack plots show the transformation of Zn (overlapping peaks 110 and 103) to ZnO (peak 112) in the anode (third column) and the progression of the MnO2 (peak 100) to MnOOH (peak 210) reaction in the cathode (fourth column). The cathode reaction is observed as a peak shift because the materials form a continuous solid solution (Gallaway et al., 2015). |
