| 中文摘要: |
| 对比了采用共沉淀法和电沉积法可控制备的Ni(OH)2的微观形貌结构及其在镍锌电池应用中的性能表现。研究发现：两种方法制备出的Ni(OH)2的晶型不同，其微观形貌也存在较大差异，共沉淀法制备得到片层结构组装成的花状α-Ni(OH)2，而电沉积法制备得到类珊瑚状结构的β-Ni(OH)2；当将两种类型的Ni(OH)2作为正极材料应用于镍锌电池时，共沉淀法所得Ni(OH)2表现出更为优异的电化学储能性能，其在0.5 A/g 的电流密度下容量可达232.1 mA·h/g。 |
| 英文摘要: |
| 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. |
