Title: Effects on structure of nickel hydroxide doped with zinc
Abstract: Nickel hydroxide was prepared through different methods such as chemical coprecipitated with zinc,mechanically mixed with Zn(OH)2 powder or undoped,and effects of doped form and amount of zinc on crystal type and structure were investigated.The measurement results of XRD indicated that the samples prepared by chemical coprecipitated with zinc were β-Ni(OH)2 when the amount of zinc is less than 11%,with better crystal structure,and more crystal defects,all of these will improve the electrochemical performance of Ni(OH)2.But the characterize lines arised in the XRD patterns,when the amount of zinc is more than 11% by chemical coprecipitation,1% by mechanical mixing with Zn(OH)2.This result shown that there is two phases in the sample,which will not beneficial to improving the electrochemical performance of nickel hydroxide.
