چکیده انگلیسی
In order to control the size and distribution of the high conductive Fe2P in LiFePO4/Fe2P composite, two different cooling rates (Fast: 15 °C·minâ1, Slow: 2 °C·minâ1) were employed after mechanical alloying. The discharge capacity of the fast cooled was 83 mAh·gâ1 and the slow cooled 121 mAh·gâ1. The particle size of the synthesized powder was examined by transmission electron microscopy and distribution of Fe2P was characterized using scanning electron microscopy (SEM). In addition, two-step heat treatment was carried out for better distribution of Fe2P. X-ray diffraction (XRD) and Rietveld refinement reveal that LiFePO4/Fe2P composite consists of 95.77% LiFePO4 and 4.33% of Fe2P.
