Electrochemical behaviors of zinc in alkaline solutions are becoming increasingly important primarily because zinc is employed in electrochemical generators as an anode.The zinc-air cell shows good cell performance as it has high energy and power densities due to its large cell voltage thanks to the large negative reduction potential of zinc and its favorable oxidation kinetics.To study the electrode kinetics of zinc oxidation,we conducted staircase cyclic voltammetry(SCV)-Fourier transform electrochemical impedance spectroscopy(FTEIS)combined experiments.
