a Galvanostatic Zn plating/stripping stability of symmetric Zn | |Zn cells using ZnSO4 + KI and TMAF electrolytes under 4 mA cm–2, 1 mAh cm–2. The inset curves provide enlarged views of 2-8 cycles and 510–516 cycles. b SEM images of Zn negative electrodes after 15 minutes of Zn deposition at 4 mA cm–2 in ZnSO4 + KI and TMAF electrolytes, scale bar=5 μm. c XRD patterns, d the corresponding RTC and e Inverse pole maps of Zn negative electrodes after 1 hour of Zn deposition at 4 mA cm–2 in ZnSO4 + KI and TMAF electrolytes, scale bar = 2 μm. f Crystal orientation analysis. g Binding energies of H2O, Zn2+ and TMA+ on Zn (002), Zn (100) and Zn (101) planes. Schematic illustration of h Zn dendrite formation and i electrostatic shielding effects. Source data are provided as a Source data file.
