摘　　要：采用行星球磨法制备磷酸铁锂前驱体微粉,并通过激光粒度分析仪对磷酸铁锂前驱体的粒径大小及分布进行表征。主要研究了球料比、球磨时间和球磨转速等球磨工艺对磷酸铁锂前驱体粒径大小及分布的影响。结果表明:通过行星球磨可以获得粒径为微米级别的磷酸铁锂前驱体微粉,最佳的工艺条件是球料比3∶1、球磨转速200 r/min、球磨时间10 h。Lithium iron phosphate precursor powder was successfully prepared by planetary ball mill. The particle size and distribution of Lithium iron phosphate precursor were determined by the particle size analyzer respectively. The influence of milling process parameters, such as the ball material ratio, milling time and milling speed, on the crystal structure, morphology, particle size and distribution of the Lithium iron phosphate precursor powder were main studied in detail. The results show that the planetary ball mill can obtain Micron lithium iron phosphate precursor powder and the best milling process conditions are ball material ratio of 3 ： 1, ball speed of 200 r/rain, the milling time of 10 h.
