The Structure and Electrochemical Performance of α/β Mutually Embedded Nickel Hydroxide
α/β互嵌氢氧化镍电极活性材料的结构和电化学性能

α/β mutually embedded nickel hydroxide has been synthesized by chemical coprecipitation method. The microstructure and surface morphology of the prepared samples were analyzed by X–ray diffraction (XRD), Fourier transform infrared (FTIR), and scanning electron microscopy (SEM). The electrochemical performance of the prepared sample was characterized by cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and charge discharge tests. Compared to the pure β nickel hydroxide, the α/β mutually embedded nickel hydroxide shows a higher electrochemical reaction activity, lower electrochemical reaction impedance, higher discharge capacity, and higher discharge voltage. Moreover, α/β mutually embedded nickel hydroxide has better cyclic performance.
