“…Metal–air batteries deliver higher theoretical energy density than that of conventional Li-ion batteries and are considered as a robust and viable electrochemical energy storage means for next generation electric vehicles. − The simple yet effective design of metal–air batteries which consists of metal anode, air breathing cathode and an appropriate electrolyte is very alluring . Discharging of any particular metal–air battery involves few steps that include the transformation of metal into ions at the anodic surface and oxygen into hydroxide ions at cathodic surface.…”

Neutral aqueous electrolyte-based aluminum−air (Al−air) batteries have managed to gather significant attention because of their characteristic safety and cost effectiveness. However, the formation of the passivation layer [Al(OH) 3 ] on the aluminum anode inhibits the long-term shelf life of the battery. Herein, a novel strategy to overturn the passivation by altering the aluminum/electrolyte interface is proposed. Incorporation of synergistic reductive electrolysis mixture additives (Tiron + NaNO 3 ) can significantly reduce the passivation of the aluminum anode. The efficacy of the Tiron + NaNO 3 synergistic mixture additive has been systematically examined using half-cell and full-cell with different concentrations of the additives in 0.5% NaCl. Furthermore, dual cell performance was investigated with optimum concentration (0.005 M Tiron + 0.005 M NaNO 3 ) of the additive in 0.5% NaCl as the anolyte and different concentrations of H 2 SO 4 as the catholyte. It is found that the resulting pumpless dual cell battery comprising neutral electrolyte with 0.005 M Tiron + 0.005 M NaNO 3 mixture additive as the anolyte and 1 M H 2 SO 4 as the catholyte demonstrated a remarkable cell potential of 1.14 V at a current density of 1 mA g −1 , which is closer to the theoretical value. Morphological investigations using optical microscopy studies and X-ray photoelectron spectroscopic investigations also confirmed that the Tiron + NaNO 3 additive is effective in preventing the discharge product on both anode and cathode surfaces and thus resulting in enhanced battery performance.

“…7,8 Many papers have focused on reducing the corrosion rate by alloying magnesium anodes [9][10][11][12][13] and adding corrosion inhibitors to electrolyte. [14][15][16][17][18] Al and Zn are elements that can improve the corrosion resistance of magnesium anode, but AZ series magnesium alloys have poor discharge activity as magnesium anodes. 19,20 Addition Al and Pb elements make AP65 anode have higher discharge activity, due to the solution-redeposition of Al and Pb elements on anode surface.…”

Three kinds of water-soluble graphene, polystyrene sulfonate, titanate coupling agent and glucose/reduced graphene oxide were prepared for fabricating magnesium-air batteries with AP65 anode. Corrosion behavior and discharge performance were investigated. The three kinds of water-soluble graphene added respectively in NaCl solution result in a more negative potential and a lower exchange current density in the potentiodynamic polarization curve of AP65 anode. The comprehensive discharge performance of the magnesium-air battery with the polystyrene sulfonate/reduced graphene oxide (PSS/RGO) is better than other batteries. This is due to non-covalent adsorption of PSS on RGO and π−π interactions formed between PSS and RGO, which prevents graphene from agglomeration. PSS/RGO not only improves the ionic conductivity of solution, but also reduces the anode corrosion. X-ray diffraction, Fourier transform infrared spectrophotometry, scanning electron microscopy, and electrochemical impedance spectroscopy results correlate well with the discharge and corrosion performance of AP65 anode in three water-soluble graphene solutions.
