▎ 摘  要

Currently, seeking the impressive electrode material with superior performance used in lithium-ion batteries (LIB) is an emerging field of exploration. Aiming at the bad cyclic stability and poor rate performance of MnO anode materials in LIB, a simple and effective strategy adopted by preparing hybrid material composed of MnO nanostructures. In this paper, we report that the nitrogen-doped (N-doped) thermally reduced graphene oxide quantum dots (rGO QDs)-MnO composites synthesized by simple electrospinning method and toward enhanced-performance Li-ion battery. After a series of characterization and test, the rGO QDs-MnO electrode material still shows a high stable capacity of ca.760 mAh g(-1) after 300 cycles with a current density of 0.1A g(-1); it has a great improvement compared with pure MnO. Moreover, the rGO QDs-MnO composites have exhibited excellent rate capability. In fact, the introduction of N-doped rGO QDs not only improves the structure mechanical property but also facilitates the carrier transport in the MnO nanowires, acting as an effective sensitizer to enhance the reaction kinetics.
