SEM images of (a-d) bare Zn and (e-h) 3D-ULPT-Zn anodes deposited at various areal capacities with a fixed current density of 5 mA cm-2. In situ optical microscopy visualization of Zn deposited on (i) bare Zn and (j) 3D-ULPT-Zn anodes. k The current-time (i-t) curves of bare Zn and 3D-ULPT-Zn anodes at an overpotential of -150 mV. l Schematic illustration of the Zn deposition process in bare Zn and 3D-ULPT-Zn anodes. Scale bar: 5 μm for a-h (1 μm for the insets) and 100 μm for i-j
