纳米β-(OH)_2的配位沉淀法合成和电化性能研究

The Studies on Synthesis and Electrochemical Performances of Nanometer-sizeβ-Ni(OH)_2 by The acetylacetone coordination precipitation method

乙酰丙酮配位沉淀法合成nmβ-Ni(OH)2。正交法优化了合成条件。采用XRD、SEM等对其组成、结构、形态进行表征。同时测定样品的电化学性能。结果表明,10ml/L吐温-80、80℃陈化6h、0.4mol/LNiSO4与0.8mol/L NaOH以1ml/min流速双液并流的优化样品,放电比容量、大倍率放电性能等电化学性能较佳。

he method was introduced that nm β-Ni （OH）2 was synthesized by aeetylaeetone coordination precipitation method.The best conditions for preparing nm β-Ni （OH）2 was obtained by orthogonality experiment.Then determined its constitution and conformation by XRD,SEM and so on.Furthermore we found that more excellent electrode reversibility of the nm β -Ni（OH）2 sample had synthesized by addgin 0.4mol/L NiSO4 and 0.8mol/L NaOH into the reaeker at a speed of 1ml/min,10ml/LTowwen-80 and 80℃ ageing 6h.
