In-situ optical microscope images of zinc deposition in a blank and b 20% EFA at 1.0 mA cm−2 (the testing temperature is 25 °C). Two kinds of electrolytes during plating/stripping at 30 mA cm−2 within 120 min: two-dimensional contour diagram of H2 production in c blank, d 20% EFA. In-situ FTIR patterns of e blank and f 20% EFA during plating/stripping process at 1.0 mA cm−2, 1.0 mAh cm−2 (S-H, M-H, and W-H are strong, medium, and weak H-bonds, respectively.). COMSOL simulations about g, h electric field intensity and i, j Zn2+ concentration across the negative electrode surface.
