“…In the EIS spectra, the diameter of the semicircles represents the charge transfer resistance at the electrode in the solution interface. The difference between the | Z | values from high to low frequency provides the total resistance ( R total ) of the surface of Al anode, which will vary according to the anode surface activity. , A lower R total value represents a high activity of the anodic surface, which in turn would afford higher performance in the Al–air battery . The electrochemical parameters including the solution resistance ( R s ) and charge transfer resistance ( R ct ) have been obtained from impedance fitting and the values are compared in Table .…”

“…38,39 A lower R total value represents a high activity of the anodic surface, which in turn would afford higher performance in the Al−air battery. 3 The electrochemical parameters including the solution resistance (R s ) and charge transfer resistance (R ct ) have been obtained from impedance fitting and the values are compared in Table 1. It can be observed from Figure 1B that a relatively lesser R total was observed for the Tiron additive-based electrolyte than that observed with bare 0.5% NaCl electrolyte.…”

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.

“…[135] A pure Al electrode in aqueous electrolytes causes corrosion and passivation of the surface of Al due to side reactions (Al 2 O 3 and Al(OH) 3 ), which is the major limitation of pure AABs. [141] The alloying of yttrium-stabilized zirconium (YSZ) with Al has better oxidation resistance. The potential interaction of Zr 4 + cations with developing oxide coatings on the electrode surface to produce pairs with vacancies may be the cause of the increase in oxidation resistance rate.…”

Aluminum‐air batteries (AABs) are regarded as attractive candidates for usage as an electric vehicle power source due to their high theoretical energy density (8100 Wh kg−1), which is considerably higher than that of lithium‐ion batteries. However, AABs have several issues with commercial applications. In this review, we outline the difficulties and most recent developments in AABs technology, including electrolytes and aluminum anodes, as well as their mechanistic understanding. First, the impact of the Al anode and alloying on battery performance is discussed. Then we focus on the impact of electrolytes on battery performances. The possibility of enhancing electrochemical performances by adding inhibitors to electrolytes is also investigated. Additionally, the use of aqueous and non‐aqueous electrolytes in AABs is also discussed. Finally, the challenges and potential future research areas for the advancement of AABs are suggested.

Aluminum–air battery (AAB) is a promising candidate for next‐generation energy storage/conversion systems due to its cost‐effectiveness and impressive theoretical energy density of 8100 Wh kg−1, surpassing that of lithium‐ion batteries. Nonetheless, the practical applicability of AABs is hampered by the occurrence of serious self‐corrosion side reactions and substantial capacity loss, resulting in suboptimal anode utilization. Consequently, improving the anode utilization to facilitate the construction of high‐performance AABs have attracted widespread attention. Herein, the fundamentals and strategies to enhance aluminum anode utilization are reviewed from modifications of aluminum anodes and electrolytes. This comprehensive review may provide a scientific tool for the development of novel AABs in the future.
