New observation of morphology of Li[Fe1−xMnx]PO4 nano-fibers (x=0, 0.1, 0.3) as a cathode for lithium secondary batteries by electrospinning process Original Research Article

The key issue with lithium iron phosphate (LiFePO4) is poor ionic conductivity. Electrospinning is one of the best way to increase a surface area. Therefore, electrospinning was presently adopted to solve the kinetic problems associated with the solid-state diffusion of Li+ intercalation. In this work, nano-fibers of Li[Fe1−xMnx]PO4 (x=0, 0.1, 0.3) were prepared from sol–gel precursor by electrospinning. After calcinations of the precursor nano-fibers at 800 °C, Li[Fe1−xMnx]PO4 nano-fibers (x=0, 0.1, 0.3) with a diameter of 100–500 nm were successfully obtained. X-ray diffraction (XRD), videoscope, field emission scanning electron microscope (FE-SEM) and atomic force microscopy (AFM) analyses were performed to characterize the properties of the prepared materials. The purpose of the present study is to investigate the morphology change of nano-sized Li[Fe1−xMnx]PO4 (x=0, 0.1, 0.3) obtained through electrospinning. Li[Fe1−xMnx]PO4 (x=0.1, 0.3) nano-fibers displayed a rough surface due to the increased manganese content. To the best of our knowledge, this is the first report of its kind.
