Flexible and free-standing MnOx/reduced graphene oxide paper with excellent cycling stability for Li-ion battery anode

In this study, the performance of manganese oxide nanorods/reduced graphene oxide (MnO x /rGO) composite papers as anode for lithium-ion battery is investigated. The self-supporting and flexible composite papers are fabricated via traditional vacuum filtration. The crystal structure, chemical state and morphology are determined by XRD, XPS and SEM, respectively. And the electrochemical performance is measured by means of cyclic voltammetry (CV) and galvanostatic charge/discharge (GCD) techniques. It is proved that the MnO x /rGO papers exhibit layer-by-layer structure in which rod-shaped MnO x is sandwiched among the rGO sheets. As anode for lithium-ion batteries, the capacity of MnO x /rGO paper can be stabilized at 518 mAh g −1 for 1500 charge/discharge cycles.
