Facile synthesis of perovskite CeMnO nanofibers as an anode material for high performance lithium-ion batteries.

A facile synthesis of perovskite-type CeMnO nanofibers as a high performance anode material for lithium-ion batteries was demonstrated. The nanofibers were prepared by the electrospinning technique. The characterization of CeMnO nanofibers was carried out by X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy. SEM images manifested nanofibers with a diameter of 470 nm having a rough surface with a porous structure. TEM images were consistent with the observations from the SEM images. The electrochemical properties of CeMnO perovskite in lithium-ion batteries were investigated. The CeMnO anode exhibited a discharge capacity of 2159 mA h g with a coulombic efficiency of 93.79%. In addition, a high cycle stability and a capacity of 276 mA h g at the current density of 1000 mA g can be effectively maintained due to the high Li conductivity in the CeMnO anode. This study could provide an efficient and potential application of perovskite-type CeMnO nanofibers in lithium-ion batteries.
