Facile synthesis of perovskite CeMnO3 nanofibers as an anode material for high performance lithium-ion batteries

摘要

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.
