Ni(OH)2正极材料可控制备及其镍锌电池性能研究
Controlled preparation of Ni(OH)2 cathode materials and their electrochemical performances in nickel-zinc batteries
摘要
Abstract
The microstructures of Ni(OH)2 cathode materials were controllably prepared by co-precipitation and electrodeposition methods and their performances in nickel-zinc batteries were compared.It was found that both crystal structures and microscopic morphologies of Ni(OH)2 prepared by these two methods were quite different.The flower-like α-Ni(OH)2 assembled with lamellar structure can be obtained by co-precipitation method,while the coral-like β-Ni(OH)2 can be obtained by electrodeposition method.It can be observed that the Ni(OH)2 obtained by co-precipitation method shows better electrochemical energy storage performances than that by electrodeposition method with the capacity of 232.1 mA·h/g at a current density of 0.5 A/g.关键词
