Fabrication and electrochemical characteristics of electrospun LiMn2O4 nanofiber cathode for Li-ion batteries

The LiMn2O4 nanofiber cathode was synthesized by electrospinning. It forms porous network-like morphology with 150 nm in diameter and similar to 20 mu m in length. For comparison. LiMn2O4 nanoparticle cathode was synthesized by the sol-gel thermolysis process. The nanofiber cathode processes superior cycling stability and rate capacity. The AC impedance results show that the nanokber cathode has much lower degradation, probably due to the suppressed Mn3+ disproportionation process. Crown Copyright (C) 2013 Published by Elsevier By.
