title: Enabling catalytic oxidation of Li2O2 at the liquid-solid interface: the evolution of an aprotic Li-O2 battery.
abstract: We show that by using a suitable soluble redox mediator, the charging overpotential can be reduced and the round-trip efficiency can be improved in an aprotic Li-O2 battery. Not only do we explore a new redox couple, 10-methyl-10H-phenothiazine, as a soluble catalyst that improves the electrochemical performance, but we also propose possible challenges that need to be overcome for the future improvement of aprotic Li-O2 batteries.
