A Review on Metal-air Batteries with an Emphasis on the Electrochemical Performance of Aluminum-air Batteries
J. Environ. Nanotechnol., Volume 14, No 2 (June 2025) pp. 300-318
Abstract
Enhancing global decarbonization programs and assisting the transition to sustainable energy systems are both made possible by energy storage technology. Among the several electrochemical storage technologies, batteries stand out for their adaptability and their role in mitigating climate change. One potential alternative for next-generation energy storage is rechargeable metal-air batteries, which have environmental benefits and a high energy density. Electric cars, portable electronics, and large-scale energy storage for renewable source integration are just a few of the many uses for these batteries. With an emphasis on the electrolyte, metal anode, and air cathode, this paper offers a thorough evaluation of current advancements in metal-air battery technology. Systems using zinc, magnesium, sodium, lithium, and air provide high-performance metal-air batteries. There are clear benefits to energy efficiency and environmental friendliness offered by each of these methods. The promising combination of low production costs and high energy density has piqued the interest of many researchers in aluminum-air batteries. They are also being studied for ways to enhance their electrochemical properties, which might make them useful in future energy storage systems. Recent advances and strategic techniques in metal-air battery research are outlined in this study, which could help their greater implementation in electrification and energy storage technologies.
