部分杂质对球形氢氧化镍结构及电性能的影响

Effects of several impurities on crystal texture and electrochemical characteristics of nickel hydroxide

许多文献介绍了化学组成和晶体结构对Ｎｉ（ＯＨ）２电性能的影响，而化学组分对组成Ｎｉ（ＯＨ）２晶体的亚晶定向生长结构以及枝晶结构对电性能的相互影响却很少涉及。本文主要探讨硫酸盐、碳酸盐及共沉淀法掺入的少量Ｃｏ、Ｚｎ、Ｃｄ等对氢氧化镍亚晶结构和电性能的影响，以及亚晶晶粒的大小及排列方式对氢氧化镍的结构和综合电性能的影响。

A great deal of research work in literature reveals the influence of chemical composition and crystal texture on the electrochemical performance of Ni(OH) 2,but both the mutual action of chemical composition to the orientated growing texture of the crystallites,and the dendritic crystal structure to the electrochemical characteristics of nickel hydroxide were seldom dealt with.Both the mutual influence of a certain amount of sulfate,carbonate,Co,Zn,Cd hydroxide by coprecipitation on the crystallite stacking structure and electrochemical performance,and the effect of crystallite size and stacking order on the crystal texture and electrochemical characteristics of nickel hydroxide were discussed in this paper.
