Study on the Y-doped α-Ni(OH)2
Abstract:
Y-doped α-Ni(OH)2 has been synthesized by partially substitution of nickel hydroxide with Y.The structure, morphology and composition of the compound have been investigated by X-ray diffraction.Fourier transform infrared spectroscopy and scanning electron microscopy.The prepared Y doped α-Ni(OH)2 has larger packed density(1.6 g/mL), greater specific capacity(>330 mA·h/g) and higher utilization ratio(>95%) of active material than the aluminum doped α-Ni(OH)2 and U-Ni(OH)2.Cyclic voltammetry suggests that the compound has better reversibility.
