氢氧化镍是镍氢等高能碱性电池重要的正极活性材料,也是制备锂离子电池镍基正极材料重要的前驱体,一直是人们研究的热点之一。按其颗粒形貌和结构分类就近期文献中报道的制备方法以及表面修饰方式进行了综述,并对存在的问题以及未来的发展提出了一些看法。
As an important cathode active material of high energy alkaline batteries( Ni-MH, Ni-Cd,etc. ), as well as an important precursor of nickel based cathode materials for lithium ion batteries, the study on nickel hydroxide has been one of the hotspots in the area of the battery materials. In this paper, the preparation methods and surface modification technologies of nickel hydroxide in the recent years are reviewed, accoding to the classification by its particle morpholgy and crystal structure. At the same time, some new ideas for solving existing problems and the development of further researh are put forward.
