Aluminum-air (Al-air) batteries have gained significant attention due to their high energy density and specific capacity, making them promising for electric vehicles and grid-scale energy storage. However, aluminum corrosion remains a major bottleneck in their design and performance. This review provides a comprehensive overview of Al-air batteries, including their reaction mechanisms, electrochemical characteristics, and the latest advancements in electrolyte, air cathode, and anode modifications. The paper discusses the challenges and future prospects of Al-air batteries, emphasizing their potential as a sustainable alternative to lithium-ion batteries. Key components such as the anode, electrolyte, and air cathode are analyzed, along with strategies to enhance their performance. The review also highlights the importance of rechargeability and the environmental benefits of aluminum-based batteries. Despite the progress, issues like corrosion and stability need to be addressed to fully realize the potential of Al-air batteries in large-scale applications.Aluminum-air (Al-air) batteries have gained significant attention due to their high energy density and specific capacity, making them promising for electric vehicles and grid-scale energy storage.
