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.
Aluminum air batteries are electrochemical devices. They use aluminum as the anode and oxygen from the air as the cathode. In this process, aluminum oxidizes while oxygen reduces, forming a galvanic cell. This reaction generates energy efficiently, making aluminum air batteries a sustainable option for energy sources.
Here, aluminum–air batteries are considered to be promising for next-generation energy storage applications due to a high theoretical energy density of 8.1 kWh kg −1 that is significantly larger than that of the current lithium-ion batteries.
These batteries convert the chemical energy in aluminum into electricity. They utilize the electrochemical reaction between aluminum and oxygen from the air. This process generates electricity while producing aluminum oxide as a byproduct. In electric vehicles, aluminum-air batteries can supplement traditional lithium-ion batteries.
Unlike conventional batteries, aluminum-air batteries are non-rechargeable; they require aluminum replacement rather than recharging. According to the Journal of Power Sources, aluminum-air batteries exhibit theoretical energy densities of approximately 1,500 Wh/kg.
These performance limitations and environmental concerns lead to ongoing debates about the viability of aluminum-air battery technology. Performance limitations in aluminum-air batteries impede their commercial applications. Limited energy efficiency refers to the lower energy yield compared to conventional batteries.
