摘　　要：锂离子电池正极材料-LiCoO2、LiNiO2、LiMn2O4的粉末颗粒形貌直接影响到材料的电化学性能,由于球形粉体颗粒间的堆积空隙较少,粉体堆积密度较高,会使锂离子电池的电化学性能得到进一步的提高,因此球形化是锂离子电池正极材料的重要发展方向。本文主要介绍了锂离子电池球形LiCoO2、LiNiO2派生物、LiMn2O4正极材料的制备方法,并对这些球形正极材料的电化学性能同相应的非球形正极材料进行了比较,希望能够为锂离子电池材料的研究者提供借鉴。Lithium--ion battery cathode material--LiCoO2, LiNiO2, LiMn2O4 directly affect the morphology of the electrochemical battery performance, spherical lithium--ion battery cathode material is an important research direction, and because of their small contact surface between particles, the smaller gap between the particles, higher packing density powder, spherical lithium--ion battery cathode materials will be commercialized in the future. This paper reviews the comparison of the non--spherical spherical cathode material and the spherical cathode material properties, hope it can provide some reference to anybody who have been engaged in the battery material domain.
