Abstract:
LiFePO4 nanocrystalline particles were synthesized using microwave assisted polyol process within a fast reaction time of 20 minutes without any further heating as a post step. The synthesized LiFePO4 nanocrystalline particles showed mono-dispersed rod and orthorhombic-like shapes with a size of 60 approximately 180 nm. The refined X-ray diffraction pattern of the sample was indexed well to the olivine crystal structure (space group: Pnma) without any impurity phases. The LiFePO4 nanocrystalline particles show a capacity of 161 mAh/g in a voltage range of 2.5-4.2 V with a current density of 0.1 mA/cm2 without any observable capacity fading in extended cycles of 100th. A cyclic voltammetry analysis exhibits distinctly sharp peaks corresponding to the typical LiFePO4/FePO4 redox couples and demonstrates a good reversibility of the sample.
