Figure 4. (A) H₂ evolution from a Mg working electrode in 0.5 M NaCl (green), 0.5 M NaCl + 0.05 M NaH₂PO₄ (blue), 0.5 M NaH₂PO₄ (red) and 0.5 M NaNO₃ (orange) electrolytes^[44]. (B) Discharge profiles of Mg-air batteries working with electrolytes with/without DG additives under different current densities^[47]. (C) Discharge profiles of commercial pure Mg with NTA and Tiron electrolyte additives at concentrations of 0.001, 0.005, 0.01, 0.05, and 0.1 M. The insets show macrographs of the anode surface after 24 h^[48]. (D) Potentiodynamic polarization profiles for Mg anode in a 3.5% NaCl electrolyte with and without WSG^[49].
