摘　　要：本文综述了-αNi(OH)2在碱液中稳定存在的影响因素,对保持Ni(OH)2的alpha型结构所需条件及解决措施做了阐述;介绍了国内外-αNi(OH)2电极的最新研究进展,着重叙述了Al3+、Mn3+和Zn2+替代Ni2+的-αNi(OH)2的制备、稳定性和电化学性能以及尿素热分解制备的-αNi(OH)2的特性;展望了纳米级α-Ni(OH)2的研究及应用前景。The factors that affect the stability of α-Ni（OH）2 in alkaline electrolyte, as well as the conditions and measures to hold its alpha phase are reviewed in this paper. The up-to-date research and development of α-Ni（OH）2 is presented, especially the preparation, stabilization and electrochemical performance of α-Ni （OH）2 through partially substituting Al^3 , Mn^3＋ and Zn^2＋ for Ni^2＋ . Synthesis of nickel hydroxide powders by urea thermal decomposition is narrated and the research and application of nanocrystalline α-Ni（OH）2 are prospected.
