Özet
LiFePO4/CNT/C composite nanofibers were synthesized by using a combination of electrospinning and sol–gel techniques. Polyacrylonitrile (PAN) was used as the electrospinning media and carbon source. Functionalized CNTs were used to increase the conductivity of the composite. LiFePO4 precursor materials, PAN and functionalized CNTs were dissolved or dispersed in N,N–dimethylformamide separately and they were mixed before electrospinning. LiFePO4 precursor/CNT/PAN composite nanofibers were then heat-treated to obtain LiFePO4/CNT/C composite nanofibers. Fourier transform infrared spectroscopy measurements were done to demonstrate the functionalization of CNTs. The structure of LiFePO4/CNT/C composite nanofibers was determined by X–ray diffraction analysis. The surface morphology and microstructure of LiFePO4/CNT/C composite nanofibers were characterized using scanning …
