摘要

采用层层自组装法制备了五氧化二钒/还原氧化石墨烯(V₂O₅/RGO)复合材料。利用X射线衍射(XRD)、扫描电子显微镜(SEM)、傅里叶变换红外光谱仪(FT-IR)对样品的结构及形貌进行了表征,采用三电极体系测试了V₂O₅/RGO复合材料的比电容量、循环稳定性、充放电性能。结果表明,所制备的V₂O₅/RGO复合材料呈层状结构,V₂O₅和RGO的层间距分别为1.2990nm和0.9019nm,较大的层间距有利于Li⁺在纳米片间迁移;当V₂O₅与氧化石墨烯(GO)的投料比为2∶1时,在0.5mol/L的Li₂SO₄电解液中,复合材料的比容量为552.04F/g,经过500次循环后,比容量保持率为87.02%。

Abstract

V₂O₅/graphene oxide (V₂O₅/RGO) composite was prepared by layer by layer self-assembly.The structure and morphology of the samples were characterized by X ray diffraction(XRD),scanning electron microscopy (SEM) and fourier transform infrared spectroscopy(FT-IR).The specific electrical capacity,cyclic stability and charge discharge properties of the V₂O₅/RGO were tested by three electrode system.The results shown that the V₂O₅/RGO presented layered structure,the interlayer spacing of V₂O₅ and RGO were 1.2990nm,0.9019nm respectively,which was beneficial to the migration of Li⁺ in the gallery.The ratio of V₂O₅ and graphene oxide was 2∶1,the specific capacity was 552.04F/g in the Li₂SO₄(0.5mol/L) electrolysis solution and the retention rate of specific capacity was 87.02% after the 500 recycle.
