摘　　要：本文通过电化学沉积法制备了3D镍纳米阵列电极材料。通过X-射线衍射仪(XRD)和扫描电子显微镜(SEM)表征了电极材料的晶态结构和微观形貌,同时详细研究了其电化学性能。制备的电极材料具有3D镍纳米阵列结构,极大地提高了其离子传输速度,进而提高了其电化学性能。该电极的比容量能达到500F/g,在电流密度不断增加的情况下电极的容量损失较少,依然能达到80%。该电极材料在超级电容器领域具有很好的应用前景。In this paper,3 D nickel nano array electrode materials were prepared by electrochemical deposition.The crystalline structure and microscoic morphology of the prepared electrode material were characterized by X-ray diffraction(XRD)and scanning electron microscope(SEM),while their electrochemical properties were investigated in detail.The prepared electrode material has a 3 D nickel nano array structure,which greatly enhances its ion transport rate and further improves the electrochemical properties.The specific capacity of the electrode can reach 500 F/g.When the current density increases,the capacity loss of the electrode is low at increasing current density and can still reach 80%.The electrode material has good prospects for application in the field of supercapacitors.
