摘要

火焰喷雾热解是一种在管状炉中合成LiFePO4并进行热处理的方法,用于锂离子电池正极材料。采用x射线衍射仪(XRD)和场发射扫描电镜(FESEM)研究了火焰喷雾热解法制备的LiFePO4的晶体结构和形貌。根据Debye-Scherer方程,该方法获得的LiFePO4颗粒纯度高、均匀且结晶良好,粒径范围为25 ~ 60nm。FESEM数据显示,颗粒呈球形,初始粒径在15 ~ 75nm之间。

SYNTHESIS AND CHARACTERIZATION OF LIFEPO4 BY FLAME SPRAY PYROLYSIS – A LI-ION BATTERY CATHODE MATERIAL
Flame Spray Pyrolysis is a method used in the synthesis of LiFePO4 with subsequent heat treatment in tubular furnace for Li-ion battery application as cathode material. The crystal structure, morphology of LiFePO4 synthesized by Flame Spray Pyrolysis was studied by X-ray diffraction (XRD) and Field emission scanning electron microscopy (FESEM). From the Debye-Scherer equation, LiFePO4 particles obtained by this method are pure, homogeneous and well-crystallized with size ranging from of 25 – 60nm. FESEM data reveal that the particles are in spherical morphology with primary particle size ranging from 15-75nm.
