摘要
以国产V2O5粉末、H2O2、无水LiAc和Ni(Ac)2·4H2O为原料,采用溶胶-凝胶法和水热法制备了锂镍钒氧纳米材料。通过扫描电子显微镜(SEM)、透射电子显微镜(TEM)、X射线衍射(XRD)、傅里叶红外光谱(FT-IR)和电化学测试方法对材料进行了研究。结果表明:该方法所制备的锂镍钒氧纳米材料呈现均一的纳米颗粒形状,并且具有良好的电化学性能。
LiNiVO4nanomaterials were synthesized by sol-gel method and hydrothermal method with V2O5 powder,H2O2,LiAc and Ni(Ac)2·4H2O as raw materials.The morphology,structure and electrochemical performance of samples were investigated by scanning electron microscope(SEM),transmission electron microscope(TEM),X-ray power diffraction(XRD)Fourier transform infrared spectroscopy(FT-IR)and electrochemical measurements.It was found that LiNiVO4 nanomaterials prepared by these methods had excellent electrochemical performance.
