Description

LiFePO${}_4$/Carbon composite fibers were synthesized by using a combination of electrospinning and sol-gel techniques with LiOH•H${}_2$O, FeSO${}_4$•7H${}_2$O, H${}_3$PO${}_4$ and citric acid. Polyvinylpyrrolidone (PVP: 1,300,000 g.mol${}^{−1}$) was used as the fiber-forming agent in the electrospinning method and a carbon source for improving electronic conductivity of LiFePO${}_4$. Surface morphology and carbon coating features of the composite nanofibers were investigated by scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray energy dispersive spectroscopy microanalysis (EDS). The electrochemical performance of LiFePO${}_4$/carbon composite fibers were evaluated using galvanostatic charge- discharge method.
