Abstract

Al-substituted α-Ni(OH)₂ was prepared by a complexation-precipitation method and characterized by XRD.The electrochemical performance was tested by the charge-discharge method. The experimental results of orthogonal test showed that the effect order of some key preparative conditions on the electrochemical performance of Al-substituted α-Ni(OH)₂ was the concentration of aqueous ammonia, the content of aluminum and pH value.The optimum prepareative conditions for obtaining the sample with maximum specific discharge capacity (304 mAh·g^-1) were 0.5 mol·L^-1 aqueous ammonia, 15 mol% Al content and pH 11.0.
