[Abstract]

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