Source abstract
Abstract
Abstract Amorphous hydrated iron (III) phosphate has been synthesized by a coordinate precipitation method from equimolecular Fe(NO 3 ) 3 and (NH 4 ) 2 HPO 4 solutions at an elevated temperature. Hydrated iron (III) phosphate samples and the corresponding LiFePO 4 /C products were characterized by XRD and SEM. The electrochemical behavior was studied by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The LiFePO 4 /C fabricated from as-synthesized FePO 4 delivered discharge capacities of 162.5, 147.3, 133.0, 114.7, 97.2, 91.3 and 88.5 mAh g −1 at rates of 0.1 C , 0.2 C , 0.5 C , 1 C , 2 C , 3 C and 4 C with satisfactory capacity retention, respectively.
