Abstract

The properties of zinc additive and precipitation pH values on the electrochemical and microstructural characteristics of b-nickel hydroxide materials prepared by co-precipitation method have been studied. All the prepared nickel hydroxide samples showed an irregular flakes shape. A correlation between structural characteristics and electrochemical activity of b-nickel hydroxide has been established. The degree of crystallinity, crystallite size and crystal inter sheet distance of b-Ni(OH)₂ were strongly associated with the pH values of the co-precipitation reaction. The electrochemical activity is represented by the (101) diffraction line, which increases with rising pH and the percentage of zinc additive. The percentage of SO₄^2-, CO₃^2- and H₂O molecules adsorbed by b-Ni(OH)₂ crystals and the thermal stability of b-Ni(OH)₂ were related to pH. In moderately elevated pH values, the prepared b-Ni(OH)₂ materials possessed a condensed crystallite size and the substandard thermal stability. All these characteristics were expected to obtain better electrochemical activity from b-nickel hydroxide in nickel based secondary batteries.
