▎ 摘　　要

Sodium molybdate (Na-Mo-O) wrapped by graphene oxide (GO) composites have been prepared via a simple in-situ precipitation method at room temperature. The composites are mainly constructed with one dimension (1D) ultra-long sodium molybdate nanorods, which are wrapped by the flexible GO. The introduction of GO is expected to not merely provide more active sites for lithium-ions storage, but also improve the charge transfer rate of the electrode. The testing electrochemical performances corroborated the standpoint: The Na-Mo-O/GO composites delivers specific capacities of 718 mAh g(-1) after 100 cycles at 100 mA g(-1), and 570 mAh g(-1) after 500 cycles at a high rate of 500 mA g(-1); for comparison, the bare Na-Mo-O nanorod shows a severe capacity decay, which deliver only 332 mAh g(-1) after 100 cycles at 100 mA g(-1). In view of the cost-efficient and less time-consuming in synthesis, and one-step preparation without further treatment, these Na-Mo-O nanorods/GO composites present potential and prospective anodes for LIBs.
