Understanding Corrosion and Materials Deterioration in Metal–Air Batteries

Abstract

Electrochemical energy storage and conversion (EESC) technologies are important to today's energy systems. They provide sustainable solutions to the growing global demand for efficient and green energy. Among them, metal–air batteries have emerged as promising candidates due to their high theoretical specific energies and energy densities. However, like many electrochemical systems, metal–air batteries are highly susceptible to corrosion and material degradation during operation. These batteries often operate under harsh environmental conditions. Corrosion not only compromises the structural integrity of the battery but also leads to reduced efficiency, safety concerns, and shortened lifespan. Understanding the mechanisms of corrosion in metal–air batteries is therefore essential for improving their durability.
