Anodization – Deposition of aluminum alloy 6061 as the potential anode material for aluminum air battery

This study aims to investigate how altering the deposition process affects the electrochemical behavior of anodized aluminum 6061 (Al 6061). Although anodization and deposition both contribute to reducing corrosion rates by removing the oxide layer, the addition of Zn/Mn increases corrosion due to active dissolution. In this investigation, a porous matrix exhibiting an octahedral structure was created on the Al 6061 surface. Techniques like X-ray diffraction (XRD) and scanning electron microscopy (SEM) were utilized to examine the morphology of the modified aluminum surface. Cyclic Voltammetry (CV) was used to determine reduction and oxidation activity, while Electrochemical Impedance Spectroscopy (EIS) was applied to evaluate the resistance between the anode surface and the electrolyte. The specific capacity and energy density for the deposited variables were measured at 1645.83 and 1396 mWh.g − 1 , respectively. These findings indicate that modifying the aluminum surface can significantly enhance its reactivity, rendering it suitable for use as a battery anode.
