Summary In this study, FeNi/Ag cathode was made for aluminium air battery. For this purpose, FeNi‐mesh electrode surfaces were treated in two different ways (chemical and electrochemical deposition), with noble metal silver having a high catalytic activity. The optimum time for both methods was determined. The electrochemical properties were determined using cyclic voltammogram (CV), electrochemical impedance spectroscopy (EIS), and current‐potential (i‐t) curves. The battery performance tests were performed, and surface characteristics of the electrodes were determined with a scanning electron microscope an X‐ray diffraction method (SEM‐EDS and XRD). This study shows that FeNi mesh electrodes chemically and electrochemically deposited with silver are alternative for oxygen‐reducing cathodes for aluminium air battery because they are cheap, practical, and effective. The electrochemical (FeNi/Ag‐ED) deposition is better than the chemical (FeNi/Ag‐CD) deposition in terms of both economical and higher battery potential.

Solid Al–air batteries are a promising power source for potable electronics due to their environmentally friendly qualities and high energy density. However, the solid Al–air battery suffers from anodic corrosion and it is difficult to achieve a higher specific capacity. Thus, this work aims at suppressing the corrosion of Al anode by adding an electrospun Al2O3 interlayer on to the surface of the anode. The Al2O3 interlayer effectively inhibits the self-corrosion of the Al anode. Further, the effects of the thickness of the Al2O3 film on corrosion behavior were investigated. The results showed that the Al–air battery with a 4 μm Al2O3 interlayer is more suitable for a low current density discharge, which could be applied for mini-watt devices. With a proper thickness of the Al2O3 interlayer, corrosion of the anode was considerably suppressed without sacrificing the discharge voltage at a low current density. The Al–air battery with a 4 μm Al2O3 interlayer provided a significantly high capacity (1255 mAh/g at 5 mA/cm2) and an excellent stability. This wo presents a promising approach for fabricating an inhibiting corrosion interlayer for solid Al–air battery designed for mini-watt devices.

Summary In order to explore the discharge characteristics of aluminum‐air battery and find out the best discharge performance of aluminum‐air battery under the optimum working conditions, this paper studies discharge performances of an aluminum‐air battery under various ambient temperature and battery discharge conditions. The relationship between the temperature rise of the battery electrolyte and the discharge current density was studied by an experimental method. Effects of the electrolyte concentration and the ambient temperature on the battery discharge voltage were investigated. In addition, a novel method for calculating the efficiency of the aluminum‐air battery was proposed. Results show that the temperature of the aluminum‐air battery electrolyte gradually increases as its discharge current density increases and the electrolyte temperature rise could reach as high as 10°C after 60 minutes with a constant 35 mA cm−2 discharge current density. The specific energy and the specific capacity of the aluminum‐air battery first increase and then decrease as the current density increases. When the current density is 25 mA cm−2, the specific energy has a peak of 3105 Wh kg−1 for the condition of the chamber temperature 40°C and the electrolyte concentration 2 mol L−1 (2 M), while the specific capacity has a peak of 2207 Ah kg−1; furthermore, its efficiencies under various conditions increase first with the current density, reach a peak range of 19.6% to approximately 36% at 25 mA cm−2, and then decrease. These experimental results could be used as a technical guidance for the optimization in thermal management designs of the aluminum‐air battery under various operating conditions.
