Özet
LiFePO 4/graphene/C composite nanofibers, in which LiFePO 4 nanoparticles were encapsulated in graphene-containing carbon nanofiber matrix, were synthesized by using a combination of electrospinning and sol-gel techniques. Polyacrylonitrile (PAN) was used as the electrospinning media and the carbon source. Graphene was incorporated in order to increase the conductivity of the composite. PAN was dissolved in N, N–dimethylformamide (DMF). LiFePO 4 precursor and graphene were dispersed in DMF separately and were mixed with PAN solution before electrospinning. Electrospun fibers were heat-treated to obtain LiFePO 4/graphene/C composite nanofibers. The structure of LiFePO 4/graphene/C composite nanofibers was determined by X–ray diffraction analysis. The surface morphology and microstructure of LiFePO 4/graphene/C composite nanofibers were characterized using scanning electron …
