SYNTHESIS AND CHARACTERIZATION OF LIFEPO4 BY FLAME SPRAY PYROLYSIS – A LI-ION BATTERY CATHODE MATERIAL

Abstract

Flame Spray Pyrolysis is a method used in the synthesis of LiFePO 4 with subsequent heat treatment in tubular furnace for Li-ion battery application as cathode material.The crystal structure, morphology of LiFePO 4 synthesized by Flame Spray Pyrolysis was studied by X-ray diffraction (XRD) and Field emission scanning electron microscopy (FESEM).From the Debye-Scherer equation, LiFePO 4 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.
