摘　　要：锂离子电池三元材料LiNi1-x-yCoxAlyO2(NCA)为目前已经工业化应用的比容量最高的正极材料,具有循环性能好、原材料丰富和成本较低等优势,是一种极具应用前景的锂离子动力电池正极材料。但是,目前各种方法很难制备出纯相结构的LiNi1-x-y CoxAlyO2材料,并且存在首次充放电效率不高、高温稳定性能较差、振实密度低等缺点,制约着该材料的进一步应用和发展。综述了国内外三元材料LiNi1-x-y CoxAlyO2的研究进展,重点介绍了制备方法以及掺杂、包覆和表面处理等改性研究方法,并展望了LiNi1-x-yCoxAlyO2材料的未来应用和发展方向。The mixed Ni,Co,Al material has the highest capacity as the industrialized cathode of lithium-ion batteries,which has the advantages of reasonable cycle ability,low cost and rich raw materials.It is the candi-date of the potential materials for lithium ion power battery.However,it is difficult to prepare a pure phase of LiNi1-x-y Cox Aly O2 by these methods.On the other hand,the disadvantages,such as low charge-discharge effi-ciency,poor stability in high temperature and low tap density,constrained its development and application.Cur-rent research of LiNi1-x-y Cox Aly O2 material was focused on this review,including synthetic methods,doping, coating and surface treatment.The application and prospects of LiNi1-x-y Cox Aly O2 for lithium ion batteries are predicted.
