A novel concept for the synthesis of nanometric $LiFePO_4$ by co-precipitation method in an anhydrous environment

LiFePO 4 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 . LiFePO 4 precursor was characterized by TGA/DTG measurement and 650 ◦ C was found to be the optimal calcination temperature . The obtained Li F ePO 4 was characterized by X- ray diffraction (XRD), Transmission Electronic Microscopy (TEM), and nitrogen adsorption/desorption measurements ( N 2 - BET). The X- ray diffraction studies confirmed formation pure phase of orthorhombic LiFePO 4 ( Pnma space group) without any impurities. The developed co - precipitation method in an anhydrous environment is environmental friendly, cheap and can be easily scalable
