摘要：

Ni(OH)(2) including 20% Al was synthesized by solid-state reaction. The result of XRD indicated that the sample thus prepared was alpha-Ni(OH)(2), and its size and crystalline form were much poorer than those of the sample prepared by solution-state reaction. TG and DTA curves showed that alpha-Ni (OH)(2) began to decompose at higher temperature than beta-Ni(OH)(2). The electrochemical behaviors of the sample were studied by cyclic voltammetry and constant current charge-discharge experiment. It was found that the sample by solid-state reaction had more excellent electrode reversibility, higher discharge potential and higher discharge capacity.
