In this paper, we will provide an overview of recent material developments for various elements of aluminum–air batteries, including the anode, air cathode and electrolyte. Each component and material has its own strengths and challenges. This type of battery comprises three main components: an anode, a cathode and an electrolyte.
Neutral or alkaline solutions are commonly utilized as electrolytes in Al-air batteries [9, 10]. According to research, the aluminum anode cannot be fully utilized in neutral electrolytes as the specific energy density of the batteries would turn out constrained . ...
High theoretical energy densities of metal battery anode materials have motivated research in this area for several decades. Aluminum in an Al-air battery (AAB) is attractive due to its light weight, wide availability at low cost, and safety.
Aluminum's light weight, safety, ready availability, and high energy density via three-electron transfer make it an obvious candidate to consider in the pursuit of realizing metal-air battery systems. In practice, significant obstacles prevent the use of pure aluminum as an anode material in aqueous electrolytes.
In practice, significant obstacles prevent the use of pure aluminum as an anode material in aqueous electrolytes. Secondary battery designs are precluded, as evolution of hydrogen will occur before aluminum deposition can take place due to the high negative standard potential of aluminum.
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.
