【Abstract】 Ni（OH）₂ nanoparticles were prepared by homogeneous precipitation method. The morphology and structure were characterized by X-ray diffraction（XRD） and field emission scanning electron microscopy（ FESEM） respectively. Further investigation on the electrochemical performance of Ni（OH）₂ nanoparticles which used as the electrode materials was studied by cyclic voltammetry and constant current charge and discharge technology. The designing experiment includes a lot of knowledge and it is beneficial to develop students scientific literacy and comprehensive use of knowledge to carry out scientific research. Thus it can be applied as a comprehensive experimental of project in materials science.更多还原
