英文摘要	An amorphous CoSnO3@rGO nanocomposite fabricated using a surfactant-assisted assembly method combined with thermal treatment served as a catalyst for non-aqueous lithium-oxygen (Li-O-2) batteries. In contrast to the specific surface area of the bare CoSnO3 nanoboxes (104.3 m(2) g(-1)), the specific surface area of the CoSnO3@rGO nanocomposite increased to approximately 195.8 m2 g1 and the electronic conductivity also improved. The increased specific surface area provided more space for the deposition of Li2O2, while the improved electronic conductivity accelerated the decomposition of Li2O2. Compared to bare CoSnO3, the overpotential reduced by approximately 20 and 60 mV at current densities of 100 and 500 mA g(-1) when CoSnO3@rGO was used as the catalyst. A Li-O-2 battery using a CoSnO3@rGO nanocomposite as the cathode catalyst cycled indicated a superior cyclic stability of approximately 130 cycles at a current density of 200 mA g(-1) with a limited capacity of 1000 mAh g(-1), which is 25 cycles more than that of the bare amorphous CoSnO3 nano boxes.
