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.
