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.

设计用于锂离子电池具有增强电化学性能的Na-Mo-O /氧化石墨烯复合材料。

氧化石墨烯（GO）复合材料包裹的钼酸钠（Na-Mo-O）是通过简单的原位沉淀法在室温下制备的。复合材料主要由一维（1D）超长钼酸钠纳米棒构成，并被柔性GO包裹。预计GO的引入不仅会为锂离子存储提供更多的活性位，而且还会提高电极的电荷转移速率。测试电化学性能证实的观点考虑：在钠-钼- O / GO复合材料提供的718毫安g的比容量^-1在100mA克100次循环后^-1和570毫安克^-1后的高速率500次循环500 mA g ^-1; 为了进行比较，裸的Na-沫-O纳米棒示出了严重的容量衰减，这仅提供332毫安克^-1在100mA克100次循环后^-1。考虑到合成的成本效益高，耗时少以及无需进一步处理即可一步制备的优点，这些Na-Mo-O纳米棒/ GO复合材料为LIB提供了潜在的和潜在的阳极。
