The olivine type compositions LiMPO4 (M = Fe, Mn, Co) are among the most attractive materials for the positive electrode of lithium-ion battery. The benefits of using LiFePO4 are excellent cycle life, high structural stability, low cost and environmental friendliness. Here will be presented our efforts to obtain LiFePO4 powders through several synthesis methods. The differences in phase purity, microstructure, morphology, and electrochemical performances of synthesized powders were investigated by using several techniques such as X-ray powder diffraction, scanning electron microscopy, galvanostatic cycling, Mossbauer spectroscopy, and thermogravimetry. It was found that carbon coated, nanostructured particles with minimal structural imperfections showed the best electrochemical performances.
