Tris(pentafluorophenyl) borane-containing electrolytes for electrochemical reversibility of lithium peroxide-based electrodes in lithium-oxygen batteries

► TPFPB reduces the charge potential of Li2O2-based electrode. ► TPFPB mitigates the formation of Li2CO3 by the electrochemical decomposition of EC and EMC. ► The electrochemical reversibility of Li2O2-based electrode is improved in the presence of TPFPB.
