| Abstract: | Nonstoichiometric lithium iron phosphate/carbon (LiFePO4/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 LiFePO4/C nanofibers, and the sample prepared using the LiH2PO4/FeC6H5O7 ratio of 1.3 has good fibrous morphology, porous structure and high purity, thus exhibiting high capacity and stability for lithium-ion battery. |
