a, c CLSM images of bare Zn (a) and Zn(11\(\bar{2}\)0) (c) electrodes in Zn symmetric cells with a fixed areal capacity of 2.0 mAh/cm2 under different current densities ranging from 1.0 mA/cm2 to 20.0 mA/cm2. The corresponding upper and lower limit values of the colormap are 80 μm and 0 μm, respectively. b The corresponding surface roughness of the Zn electrodes in (a) (blue) and (c) (red).
