Paper Abstract

In the present work, we have successfully fabricated nanostructured LiCoO2 fibers using electrospinning technique from a viscous solution of lithium acetate/cobalt acetate/PVP (Polyvinylpyrrolidone), XRD (X-ray diffraction) and SEM (scanning electron microscopy) were performed to investigate the phase and microstructures of the electrospinning fibers respectively. Furthermore CV (cyclic voltammetry) and charge-discharge experiments were applied to characterize the electrochemical properties of LiCoO2 nanofibers. It is noteworthy that the nanostructured cathode offers a higher charge-discharge capacity compared with conventional powder or film cathodes, thus LiCoO2 nanofiber cathode may become a promising candidate for the construction of microscale lithium ion batteries due to its larger surface to volume ratio.
