摘　　要：喷雾热解法(SP)在控制所制备材料化学组成、形貌和粒径等方面有一定的优势,特别是在制备Li[Ni1/3Co1/3Mn1/3]O2和Li[Ni1/2Mn1/2]O2时,效果较好。综述了SP法的过程;介绍了SP法制备的锂离子电池正极材料的特点,如化学计量偏移小,材料结构和组成均匀,结晶度高等。<Abstrcat>Spray pyrolysis(SP) method had some advantages in control of the synthesis material composition, morphology and particle size, especially when preparing LiO_2 and LiO_2, the effect was good.The process of SP method was reviewed, the characteristics of cathode materials for Li-ion battery prepared by SP method were introduced. The shift of stoichiometry ratio was little, the material had homogeneous structure and composition, the degree of crystallinity was high.
