氢氧化镍正极材料的X射线衍射峰强比与其电化学性能关系研究
Study on the Relationship between the Intensity Ratio of X-ray Diffraction Peaks and Electrochemical Performance of Ni（OH）2 Cathode Material
【摘要】 利用"管道式合成"方法合成了5种成分相同、结构不同的Ni(OH)2样品。采用X射线衍射(XRD)、场发射扫描电镜表征材料的微观结构及参数。测试了材料的电化学性能,考察了I101/I001比值与Ni(OH)2材料电化学性能的关系。研究结果表明,随I101/I001比值的增大,样品的电化学性能呈下降的趋势。说明XRD峰强比可以作为快速表征相同制备方法及成分的Ni(OH)2材料性能的方法,简化了现有测试手段。
【Abstract】 5 kinds of Ni(OH)2 were prepared by the "conduit synthesis technology" which have same chemical contents and different micro-structures.The physical structure and morphology of the samples were characterized by X-ray diffraction and field emission scanning electron micrographs.The electrochemical performance of samples was characterized.It is found that electrochemical performance of samples devastated following the increase of values of I101/I001,which indicate that value of I101/I001 can be used to characterize the qualities of Ni(OH)2 which is made by identical way and has same chemical contents,so as to simplify present testing method.
