以氯化镍为镍盐来源，尿素为沉淀剂，采用超声法快速地合成了由纳米片组装而成的花状 Ni（OH）2微球。探讨了超声时间和功率、反应物配比等因素对 Ni（OH）2电化学性能的影响。结果表明，当超声时间为30 min，超声功率为500 W，镍盐和尿素的配比为1/4时，所得 Ni（OH）2样品的电容性能最佳，10 mA 下恒流充放电时，其放电比电容量高达1906 F/ g。

Flower-like Ni(OH)2 microspheres assembled from several dozens of nanosheets were success-fully synthesized through a rapid ultrasonic irradiation process in a very simple system composed only of water,NiCl2 and CO(NH2 )2 . The effects of the ultrasonic time and power,the reactants ratio on electro-chemical properties were discussed. The result showed that the maximum specific capacitance value of 1 906 F/ g at 10 mA could be achieved,the Ni(OH)2 flower-like microspheres obtained at ultrasonic time of 30 min,ultrasonic power of 500 W and the NiCl2 / CO(NH2 )2 ratio of 1 / 4.
