Anode Corrosion and Its Mitigation in Metal–Air Batteries—I (Li/Na/Al/Mg-Air)

Metal–air batteries, often called metal–air fuel cells, have emerged as a promising energy storage technology due to their high energy density and environmental sustainability. Nevertheless, the problem of anode corrosion poses a significant danger to their practical implementation. This chapter discusses the fundamentals of anode corrosion in air batteries, its mitigation approaches, and existing challenges, intending to gain a deeper understanding and find effective strategies to address this issue. The implications pertain to the formulation of techniques for reducing anode corrosion, which involve choosing materials resistant to corrosion such as applying protective coatings and making design adjustments can improve the dependability and effectiveness of air battery technology, thereby aiding the progress of sustainable energy storage options.
