title: A highly efficient Li2O2oxidation system in Li-O2batteries.
abstract: A novel indirect charging system that uses a redox mediator was demonstrated for Li-O2batteries. 4-Methoxy-2,2,6,6-tetramethylpiperidinyl-1-oxyl (MeO-TEMPO) was applied as a mediator to enable the oxidation of Li2O2, even though Li2O2is electrochemically isolated. This system promotes the oxidation of Li2O2without parasitic reactions attributed to electrochemical charging and reduces the charging time.
