High-capacity cathode for lithium-ion battery from LiFePO4/(C + Fe2P) composite nanofibers by electrospinning
Source abstract
Abstract
Lithium iron phosphate/(carbon and ferrous phosphide) (LiFePO4/(C + Fe2P)) composite nanofibers are successfully synthesized by electrospinning and subsequent heat-treatment. We develop a novel aqueous solution with excellent spinnability, which contains dihydrogen phosphate, ferric citrate, and polymer. Heat-treatment temperature makes great effect on the product morphology and the formation of Fe2P phase. The Fe2P phase appears when the temperature increases to 750 °C, while too high treatment temperature of 850 °C results in the destruction of fibrous morphology. The LiFePO4/(C + Fe2P) composite nanofibers synthesized using the temperature of 750 and 800 °C show high capacity for lithium-ion battery, possibly attributed to the small fiber diameter and good conductivity enhanced by Fe2P and carbon species.
