Facile synthesis of interwoven ZnMn₂O₄ nanofibers by electrospinning and their performance in Li-ion batteries

Interwoven ZnMn₂O₄ nanofibers with porous nanostructures were successfully prepared by an electrospinning technique. The scanning electron microscopy (SEM) results reveal that the obtained ZnMn ₂O₄ nanofibers are 153 nm in diameter and several micrometers in length. The X-ray diffraction (XRD) analysis shows that the nanofibers possess highly crystalline structure without any impurity phase. When evaluated as an electrode material for Li-ion batteries (LIBs), results of the electrochemical test show that these unique interwoven ZnMn₂O ₄ nanofibers exhibit admirable lithium storage performances with high specific capacity and excellent rate capability. The interwoven and continuous one dimensional (1D) nanostructure of ZnMn₂O₄ nanofibers makes a prominent contribution to the excellent electrochemical performance.
