Preparation and Electrochemical Properties of LiMn₂O₄ Nanofibers via Electrospinning for Lithium Ion Batteries

Abstract:

LiMn₂O₄ nanofibers were prepared via electrospinning and followed by calcination. The surface morphology of as-spun and pure LiMn₂O₄ nanofibers was characterized by a scanning electron microscope (SEM) with an average diameter of 180 nm. After calcination at 800 °C in air for 5 h, charge/discharge capacity of pure LiMn₂O₄ nanofibers was measured in the potential range of 3.0 to 4.3 V. Battery testing showed that LiMn2O4 have a high discharge capacity of 80 mAh/g and 85% of the initial charge capacity was maintained for 5 cycles.
