Abstract：Three dimensional flower-like NiCo2O4 was prepared by a hydrothermal method and annealing treatment. XRD, XPS and SEM were used to characterize the crystallization, element composition and morphology of synthesized material.The results showed that: 1)The crystallinity of the synthesized NiCo2O4 material was not high. 2)The material contained Ni and Co elements with different valences. The presence of the Ni2+ /Ni3+ and Co2+/Co3+ provided two active centers for the generation of pseudocapacitance. 3)As supercapacitor electrode material, the three dimensional flower-like NiCo2O4 displayed excellent electrochemical performance.
