摘要
以锂离子电池正极材料前驱体Ni_(0.60)Co_(0.20)Mn_(0.20)(OH)_2为研究对象,研究了陈化时间对连续共沉淀法制备Ni_(0.60)Co_(0.20)Mn_(0.20)(OH)_2品质和性能的影响。结果表明,随着陈化时间的延长,可以在一定程度上修饰前驱体形貌、优化一次颗粒排布,相应的会对其杂质含量、振实密度、粒径分布、比表面积造成一定的影响。该研究可为镍钴锰三元前驱体的连续工业化生产提供科学参考。
The precursor of cathode material for lithium ion batteries is the study object of this articles. The effect of aging time on the quality and properties of Ni_(0.60)Co_(0.20)Mn_(0.20)(OH)_2 prepared by continuous coprecipitation method was studied.The results show that the morphology of the precursor can be modified to some extent and the primary particle arrangement can be optimized with the aging time prolonging. Correspondingly, the impurity content, vibration density, particle size distribution and specific surface area of the precursor can be affected to some extent. This study can provide scientific reference for the continuous industrial production of the nickel cobalt manganese ternary precursors.
