分析了Zn-Ni电池兼具镍电极寿命长和锌电极比能量高、原料丰富、成本低、无污染的优势,是一种较为理想的绿色动力电池。简述了近年来美国、日本、韩国和我国对该电池的研究和发展情况,都在力求Zn-Ni电池尽快实现商品化。为了解决Zn-Ni电池存在的锌枝晶、电极变形和电池密封等难题,介绍了在电极和电解液中加入各种添加剂以及改进隔膜和充电方式等途径。

The advantages of the Zn-Ni batterie s,which include the longer cycle life of the nickel electrode and the higher specific energy,lowe r cost,rich in resource and no pollut ion of the zinc electrode,have been analyzed in this paper,that appears this battery is an idea green power so urce.The recent of the research and development of America,Japan,South Korean and China are reported.Some companies believe that this battery will have a great market share.Some methods,for example the addi tives to the electrode and elec-trolyte,improving separator and ch arging type are introduced to overcome the difficulties,such as Zn den-drite growth,shape changes of Zn ele ctrode and seal of the battery.
