Electrochemical properties of nanostructured Li[Fe0.9Mn0.1]PO4/C as a cathode material for lithium ion batteries prepared by electrospinning method

In this paper, Li[Fe_0.9Mn_0.1]PO₄/C nanofibers were successfully synthesized from a sol-gel precursor by electrospinning and used as a cathode material for lithium ion batteries. The synthesized nanofibers were smooth, and distributed uniformly, and when produced at 750 °C for 10 h in a nitrogen atmosphere had an average diameter of 100?~?300 nm. The crystal structures were studied by X-ray diffraction (XRD) and no obvious impurity-related peaks were observed. The electrochemical properties were examined using initial charge-discharge curve, cycle performance, EIS, etc. The initial discharge capacity reached about 124mAh/g. In addition, the impedance was lower than LiFePO₄.
