Figure 7. (a) Schematic diagram of a Zn symmetric cell with Ti spacer. (b) Comparison of cycle life curves for Zn symmetric cells. Cross-sectional SEM images of zinc electrodeposition on a copper substrate show distinct morphologies under different conditions. Reproduced with the authors’ permission of ref. [14] Copyright 2023, Royal Society of Chemistry. Zinc plating images at (c) low current density and (e) high current density exhibit different structural features. After zinc plating/stripping cycles, the samples reveal (d) the morphology at low current density and (f) the morphology at high current density. Top-sectional SEM images and corresponding elemental mapping further highlight the differences in zinc plating morphology at (g) low current density and (h) high current density.
