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 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.
We will focus on the specific issues in Al–air batteries, mostly related to the reactions between electrodes and electrolyte, i.e: the high dissolution of aluminum, the precipitation of insoluble carbonate, hydrogen evolution and the electrolyte evaporation or ambient moisture uptake. 4.1. Aqueous electrolytes
Aluminium–air batteries are primary cells, i.e., non-rechargeable. Once the aluminium anode is consumed by its reaction with atmospheric oxygen at a cathode immersed in a water-based electrolyte to form hydrated aluminium oxide, the battery will no longer produce electricity.
Design & assembly of Al–air batteries are the key factors in the performance and viability. Aluminum–air (Al–air) batteries, both primary and secondary, are promising candidates for their use as electric batteries to power electric and electronic devices, utility and commercial vehicles and other usages at a relatively lower cost.
Practical implementation of aluminum batteries faces significant challenges that require further exploration and development. Advancements in aluminum-ion batteries (AIBs) show promise for practical use despite complex Al interactions and intricate diffusion processes.
