The discharge and short-circuit studies of the prepared Al–air battery were undertaken using different Al alloy anodes. The results demonstrated that the Al anode having a higher ratio of nano-YSZ (5 wt%) had the highest discharge behaviour and excellent corrosion resistance making it a potential candidate as an electrode for the Al–air battery.
The short-circuit study of the Al–air battery used in Al, Al-1, Al-2 and Al-3 in 1 M KOH electrolyte over 0.5 h is shown in Fig. 6. The short-circuit voltages, currents and current densities measured during the short-circuit test are shown in Table 3.
Aluminum air battery (Al-air battery) is a type of batteries with high purity Al as the negative electrode, oxygen as the positive electrode, potassium hydroxide or sodium hydroxide as the electrolyte solution.

Aluminum–air batteries are remarkable due to their high energy density (8.1 kWh kg−1), light weight (2.71 g cm −3), environmentally friendly, good recyclability, and low cost [137,138]. Aluminum–air batteries consist of an aluminum anode, an air cathode and an electrolyte which is salty, alkaline, and nonaqueous solutions.
Aluminum corrosion in aqueous electrolytes is the biggest barrier in the application of the Al–air battery, which needs to be managed effectively for its potential use.
However, alkaline electrolytes, aluminum electrodes tend to be highly corrosive, and the main problem restricting a feasible usage of Al–air batteries is the low coulomb efficiency resulting from the self-corrosion of the electrode. To overcome this problem, aluminum alloys have been chosen as the electrode material [140–142].
