Nonstoichiometric LiFePO sub(4)/C nanofibers by electrospinning as cathode materials for lithium-ion battery

Nonstoichiometric lithium iron phosphate/carbon (LiFePO sub(4)/C) composite nanofibers are prepared by electrospinning and subsequent calcination. The ratio of raw materials exerts great effects on the morphology and electrochemical performance of LiFePO sub(4)/C nanofibers, and the sample prepared...

Description
Summary:Nonstoichiometric lithium iron phosphate/carbon (LiFePO sub(4)/C) composite nanofibers are prepared by electrospinning and subsequent calcination. The ratio of raw materials exerts great effects on the morphology and electrochemical performance of LiFePO sub(4)/C nanofibers, and the sample prepared using the LiH sub(2)PO sub(4)/FeC sub(6)H sub(5)O sub(7) ratio of 1.3 has good fibrous morphology, porous structure and high purity, thus exhibiting high capacity and stability for lithium-ion battery.
