Lithium–oxygen (Li–O2) batteries have attracted considerable attention as prospective next-generation energy storage devices because of their highest theoretical energy density among all rechargeable batteries. Although fundamental researches focusing on the properties of the solid-state discharge products have been conducted to elucidate the factors that contribute to large charge overvoltages, many questions remain unanswered. In particular, due to the main discharge product being a peroxide, which cannot remain stable in the atmosphere, its formation process, properties, and the relationship between the surface structure and its reactivity are not fully understood. The present article aims to introduce the latest understanding of the reductive growth and oxidative decomposition processes of discharge products, particularly from a surface science perspective.
