氢氧化镍材料的反应机理和电极制备

Reaction mechanism and preparation of nickel hydroxide electrode materials

目前商业化的氢氧化镍材料是β-Ni(OH)2/β-NiOOH,研究比较多的是具有螺旋结构的α-Ni(OH)2/γ-NiOOH。系统全面地阐述了氢氧化镍电极材料的物理与化学性能;综述了该材料的研究现状;探讨了未来的研究发展方向。重点分析了氢氧化镍电极的制备和电极的反应机理。

For the excellent electrochemical performanceNi（OH）2 has been used as the positive electrode materials of many kinds of secondary batteries, such as Ni-MH battery, Ni-H2 battery and Ni-Cd battery. The β-Ni （OH）2/β-NiOOH electrode materials have been used in the commercial rechargeable alkaline battery. The focus of scientific research is on the α-Ni （OH）2/ γ-NiOOH, which has a turbostratic structure. The physical and chemical properties were depicted and the recent research state was reviewed in this paper. The preparation and electrode reaction mechanism were analyzed in detail.
