Comprehensive Experimental Design Based on Synthesisand Electrochemical Properties of Nano-Ni(OH)₂

Ni(OH)2nanoparticles 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)2nanoparticles 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.
