Morphology Study of New Shaped Porous Nanotubes of LiFePO4 by Electrospinning
Porous nanotubes of lithium iron phosphate (LiFePO4) were synthesized from a metal oxide precursor by the electrospinning method. After calcination of the above precursor nanotube at 800 degrees C, LiFePO4 nanohthes with a diameter in the range of 150-500 nm, were obtained. Poly(vinylpyrrolidone) had an important role in the formation of hollow structure. The obtained nanotubes were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), videoscopy, and transmission electron microscopy (TEM), respectively. The results showed that porous and hollow morphologies of nanotubes were successfully formed by electrospinning parameters and calcination temperature.
