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.

柔性和独立的 MnOx/还原氧化石墨烯纸，具有优异的循环稳定性，用于锂离子电池负极

在这项研究中，研究了氧化锰纳米棒/还原氧化石墨烯（MnO x /rGO）复合纸作为锂离子电池负极的性能。自支撑和柔性复合纸是通过传统的真空过滤制造的。晶体结构、化学状态和形貌分别由 XRD、XPS 和 SEM 确定。电化学性能通过循环伏安法 (CV) 和恒电流充放电 (GCD) 技术进行测量。证明MnO x /rGO 纸表现出逐层结构，其中棒状MnO x 夹在rGO 片材之间。作为锂离子电池的负极，MnO x /rGO 纸的容量可以稳定在 518 mAh g -1 并进行 1500 次充电/放电循环。
