To explore the effects of adding different concentrations of Na 2 SnO 3 to 0.7 M NaCl solutions, potentiodynamic polarization, potentiostatic oxidation, electrochemical impedance spectroscopy, and scanning electron microscopy were utilized. The results show that the addition of Na 2 SnO 3 to a 0.7 M NaCl solution increases the corrosion potential of the Mg‐14Li‐3Al‐1Gd electrodes. Samples with 0.1 mM Na 2 SnO 3 retained the highest discharging current density and lowest polarization resistance of all the specimens. Electrodes in an electrolyte solution mixed with 0.1 mM Na 2 SnO 3 presented a larger active reaction area, deeper channels, and higher discharging currents than those with other additive concentrations. In conclusion, to improve the electrochemical behavior of Mg‐14Li‐3Al‐1Gd electrodes in a 0.7 M NaCl solution, the optimal concentration of Na 2 SnO 3 is 0.1 mM.Read More
