“…8 and 9) were fitted with the circuit depicted in Fig. 10b, where a charge transfer resistance (R t ) in parallel with a double-layer capacitance (C dl ) added in series of R c [44][45][46]. Further prolonging immersion time, aggressive chloride ions penetrated through the coatings, leading to continuous corrosion, hence the coatings degraded and the interfaces changed.…”

In this research, the performance of Al-air batteries based on pure Al and Al-0.5 wt%In anodes in 4M NaOH solutions with or without different concentrations of additives was investigated by galvanostatic discharge test. The characteristics of the anodes after discharge were investigated by electrochemical impedance spectroscopy (EIS), scanning electron microscopy (SEM), and energy dispersive analysis of X-ray (EDAX). The corrosion behavior of the anodes was researched by self-corrosion rate test and potentiodynamic polarization test. The results show that the Al-In alloy exhibits a low self-corrosion rate and high anodic efficiency when ZnO or Na 2 SnO 3 is added to 4M NaOH. The results of galvanostatic discharge at 20 mAcm −2 indicate that the Al-air battery based on Al-0.5 wt%In anode shows excellent discharge performance. The Al-air battery based on the alloy anode has an operating voltage of 1.3 V and anodic efficiency of 75.2% in 4M NaOH with 0.02M Na 2 SnO 3 , and an operating voltage of 1.01 V and anodic efficiency of 82.5% in 4M NaOH with 0.2M ZnO. SEM and EDAX results prove that zinc oxide or sodium stannate could inhibit the corrosion of the Al-In anode by the deposition of zinc or tin on the anode surface.Aluminum is an excellent anode material for metal-air batteries because of its high theoretical electrochemical equivalent value (2980 mAh g -1 ), which is just lower than that of lithium (3860 mAh g -1 ) and higher than those of other metals such as magnesium (2200 mAh g -1 ) and zinc (820 mAh g -1 ). 1 As promising power and energy storage devices, Al-air batteries can be applied in fields such as electric vehicles, navigation and portable sources. In addition, the final reaction product can be recovered as aluminum during recycling. However, severe self-corrosion of the aluminum anode in alkaline electrolyte causes fuel loss during standby. A protective oxide film forms spontaneously on the aluminum surface in neutral electrolyte, which slows down the active dissolution of the aluminum anode. These problems have hindered the development and business applications of Al-air batteries. 2,3 Two main methods have been proposed to inhibit the self-corrosion of aluminum anodes in alkaline solution. The first method is to dope aluminum with active metal elements. The active metal elements mainly include Ga, In, Sn, Zn and Mg. 4 As they have high hydrogen evolution overpotential, these alloying elements can reduce hydrogen evolution. An Al-air battery based on Al-1 wt%Mg-1 wt%Zn-0.1 wt%Ga-0.1 wt%Sn anode in 4M NaOH solution showed excellent discharge performance. 5 However, the addition of excessive kinds of elements is harmful to the recovery of aluminum. What's more, the amount of active metal elements added into the aluminum should be as low as possible. Therefore, researchers preferred to study some binary aluminum alloys as anodes of Al-air batteries. 6-9 For instance, Wilhelmsen studied the corrosion rate of Al-0.1 wt%In anode in 4M KOH solution by the weight loss method and the result revealed that t...

“…5 shows the discharge behavior of Mg-air battery at different discharge current densities in the absence (blank) and presence of 2.5 mM DG surfactant. From this figure it clear that the operating voltage drops quickly in the beginning stage of discharge, which may have occurred because of battery internal resistance and thereafter get into a steady state [32]. Moreover, as shown in Fig.…”
