摘要

Side reactions caused by reactive oxygen species (e.g., superoxide and singletoxygen) are limiting factors in the lithium–oxygen batteries (LOBs). Superoxidedismutase mimetics (SODms), which suppress superoxide-triggeredside reactions by accelerating the disproportionation reaction during discharge,are introduced as soluble additives in the LOBs. However, althoughSODms promote the disproportionation reaction, which is the main pathwayfor singlet oxygen evolution, the correlation between SODms and singletoxygen has not been verified. Here, 4-carboxy-TEMPO is selected as a representativeSODm that effectively promotes the disproportionation reactionand chemically verifies acceleration of singlet oxygen evolution. Furthermore,by using quencher, it is reported that the release of singlet oxygen evolvedby the SODm is decreased. Because this study closely examines the relationshipbetween the additives and singlet oxygen, it is believed that this studyprovides an important reference for the development of additives for thepractical application of LOBs.
