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.
