Effects of Corrosion on the Durability of Battery

Abstract

The term “corrosion” refers to the degradation of metallic materials (metals and their alloys) caused by a reaction with environmental factors. This phenomenon causes serious financial and health problems. Corrosion is one of the electrochemical phenomena that manifests itself as the formation of clusters on the surface of metals, where one electrode, known as the “anode”, consumes the other, known as the “cathode”, which remains dormant. In reality, these clusters form as soon as the metal surface becomes heterogeneous, forming the anode and cathode domains where the two primary electrochemical reactions (oxidation and reduction) take place. For example, dissolution or passivation of active electrode materials and dissolution, oxidation or passivation of current collectors are the main causes of corrosion in batteries. An in-depth analysis of battery corrosion is necessary due to the rapid development of battery research. We begin with an overview of recent developments in corrosion and electrode protection for different battery types.
