TY - JOUR AB - © 2017 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim Large over-potentials owing to the sluggish kinetics of battery reactions have always been the drawbacks of Li?O2 batteries, which lead to short cycle life. Although redox mediators have been intensively investigated to overcome this issue, side-reactions are generally induced by the solvated nature of redox mediators. Herein, we report an alternative method to achieve more efficient utilization of tetrathiafulvalene (TTF) in Li?O2 batteries. By coordinating TTF+ with LiCl during charging, an organic conductor TTF+Clx? precipitate covers Li2O2 to provide an additional electron-transfer pathway on the surface, which can significantly reduce the charge over-potential, improve the energy efficiency of Li?O2 batteries, and eliminate side-reactions between the lithium metal anode and TTF+. When a porous graphene electrode is used, the Li?O2 battery combined with TTF and LiCl shows an outstanding performance and prolonged cycle life.
