AbstractThe search for new stable and efficient cathode materials for nonaqueous Li-O-2 batteries has become an urgent task to satisfy the ever-growing needs for high capacity and high energy efficiency. To circumvent above issues, we have designed and synthesized isolated Au and Pd decorated MnOx nanomembranes, which act as bifunctional catalysts for Li-O-2 batteries with a high specific capacity of 3200 mA h g(-1) at 500 mA g(-1) which is 9.8 and 3.2 times that of Super P and bare MnOx, respectively. In addition, with such novel structured catalysts, lithium ions, electrons and oxygen-containing intermediates can be rapidly transported, thus greatly improving the performance of Li-O-2 batteries by significantly lowering the polarization and extending the cycle life to 120 times. The encouraging electrochemical property of such Au-Pd decorated MnOx nanomembranes leads to potential applications of the materials for high-performance Li-O-2 batteries.
