dc.description.abstract Seeking to design high-efficiency catalyst (LMO@N-rGO) for Li-O(sub2) batteries, we suggested a onestep hydrothermal strategy to grow well-crystallized spinel LiMn(sub2)O(sub4) (LMO) nanoparticles homogeneously on nitrogendoped reduced graphene oxide nanosheets (N-rGO). We found that the prepared material can yield a twin-function battery, functioning as a Li-O(sub2) (air) battery under the oxygen atmosphere and a Li-ion battery in the absence of oxygen. In the Li-O(sub2) configuration, the material displayed a lower charge plateau voltage for 0.21 V and excellent cycling performance (120 cycles at 1000 mA h g(sup-1) limited capacity). Furthermore, in the absence of oxygen, the material exhibited very good Li-ion battery cathode performance, achieving a capacity of up 80 mA h g(sup-1). On the basis of our characterization results, three reasons are suggested for the twin performance of the material: the highly uniform dispersion of LMO nanoparticles, the improved Li diffusion kinetics, and the synergic effect between the spinel LMO nanoparticles and the N-rGO. en_US
