Study on the Electrochemical Performance of Carbon-Coated LiFePO₄ Prepared by Sol-Gel Method

Abstract:

LiFePO4/C is synthesized via sol-gel method using Fe3+ as iron sources and complexing agents, followed by sintering at high temperature for crystallization. The amount of carbon in these composites is less than 6.8 wt.% and the XRD experiment confirms that all samples are pure single phase indexed with orthorhombic Pnma space group. The particle size of the LiFePO4/C synthesized by acetic acid as complexing agent is drastically fine with 200nm. The electrochemical performance of this material, including reversible capacity, cycle number and charge-discharge characteristics, exhibits better.
