摘要：
MnO nanowires/graphene (MnO/GR) composite is prepared through a simple two-step route, which including a hydrothermal and a subsequent calcination process. Morphology and structure characterizations indicate the successful incorporation of MnO nanowires with GR sheets. The electrochemical performance of the composite as an anode material for sodium-ion batteries (SIBs) was investigated. The results show that the composite could deliver good cycling performance of 191 mAh g(-1) at the current density of 50 mA g(-1) after 100 cycles together with excellent rate performance by taking the advantages of GR. This work offers promise for the potential application of MnO/GR as an anode for SIBs. (C) 2017 Elsevier B.V. All rights reserved.
