Alternatively, metal–air batteries such as Al–air batteries are a combination of both battery and fuel cell components. In these batteries, the anode consists of a solid metal electrode (Al), while the cathode utilizes the oxygen present in the air.
Aluminum-based batteries have undergone significant development since their inception, with notable milestones including the introduction of Al–MnO 2 batteries around the 1960s and subsequent efforts to improve their efficiency and applicability.
Al–air batteries are metal–air batteries that utilize aluminum as the anode and ambient oxygen as the cathode. The anodic and cathodic half–cell reactions are summarized in eqn (1) and (2), respectively, together with the corresponding overall reaction in eqn (3).
Components of Al–air battery and reaction mechanism The Al–air battery, as an energy storage system, consists of three major components, that is, anode, cathode, and electrolyte. In a battery, both electrodes are made up of solid materials, whereas in a fuel cell, the electrodes are gases.
As pure aluminum is unstable when used as an anode for Al–air batteries, the most common method to prolonging the battery operation time and decreasing the corrosion rate is through the use of Al alloys. A considerable number of alloying elements such as Ga, Tl, In, Sn, Zn, Bi, Mn and Mg have been adopted.
Aluminium–air batteries (Al–air batteries) produce electricity from the reaction of oxygen in the air with aluminium. They have one of the highest energy densities of all batteries, but they are not widely used because of problems with high anode cost and byproduct removal when using traditional electrolytes.
