A synergic combination of a soluble ­redox mediator and protected Li metal ­electrode to prevent the self-discharge redox is realized by ­exploiting 2,2,6,6-tetramethylpiperidinyl 1-oxyl (TEMPO) an Al2O3/PVdF-HFP composite ­protective layer (CPL). Stabilization simple CPL coating effective at ­suppressing chemical reduction oxidized TEMPO opens up possibility sustainable mediation for robust cycling Li–O2 batteries.
