Facile synthesis of perovskite CeMnO(3) nanofibers as an anode material for high performance lithium-ion batteries

A facile synthesis of perovskite-type CeMnO(3) 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(3) 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(3) perovskite in lithium-ion batteries were investigated. The CeMnO(3) anode exhibited a discharge capacity of 2159 mA h g(−1) with a coulombic efficiency of 93.79%. In addition, a high cycle stability and a capacity of 276 mA h g(−1) at the current density of 1000 mA g(−1) can be effectively maintained due to the high Li(+) conductivity in the CeMnO(3) anode. This study could provide an efficient and potential application of perovskite-type CeMnO(3) nanofibers in lithium-ion batteries.
