Popis: Redox mediators can enhance redox reactions in Li-O2 batteries; however, their gradual degradation remains unclear. Here the authors show that organic redox mediators are decomposed by singlet oxygen formed during cycling, indicating a strategy for the rational design of stable redox mediators.
