LiFePO4 with high purity and good crystallinity was prepared by an improved environmentally benign and low-cost co-precipitation method. The precipitate was synthesized at a room temperature using technical grade reagents on ethylene glycol as a medium. LiFePO4 precursor was characterized by TGA/DTG measurement and 650°C was found to be the optimal calcination temperature. The obtained LiFePO4 was characterized by X-ray diffraction (XRD), Transmission Electronic Microscopy (TEM), and nitrogen adsorption/desorption measurements (N2-BET). The X-ray diffraction studies confirmed formation pure phase of orthorhombic LiFePO4 (Pnma space group) without any impurities. The developed co-precipitation method in an anhydrous environment is environmental friendly, cheap and can be easily scalable.
