摘　　要：α -Ni(OH) 2 因具有较高的放电比容量 ,有望成为镍电极的活性物质。综述了用锌、铁、锰、钴和铝取代的α -Ni(OH) 2 的制备工艺及其电化学性能。在探讨α相不稳定的原因及如何使其稳定于强碱中的基础上 ,展望了其应用前景。Ni(OH) 2,which has a higher discharge capacity than α-Ni(OH) 2,has been studied as a new active material of the nickel electrode recently.In this paper ,Methods of preparing stable α-Ni(OH) 2 through substituted by manganese,iron,cobalt,aluminum and zinc ions and their electrochemical performances were reviewed.The reason that α-Ni(OH) 2 was unstable and how to stabilize it in alkaline were discussed.In addition,The prospect of α-Ni(OH) 2 in application was described.
