Synthesis and Electrochemical Property of LiMn2O4 Porous Hollow Nanofiber as Cathode for Lithium-Ion Batteries

摘要

The LiMn~(2)O~(4) hollow nanofibers with a porous structure have been synthesized by modified electrospinning techniques and subsequent thermal treatment. The precursors were electrospun directly onto the fluorine-doped tin oxide (FTO) glass. The heating rate and FTO as substrate play key roles on preparing porous hollow nanofiber. As cathode materials for lithium-ion batteries (LIBs), LiMn~(2)O~(4) hollow nanofibers showed the high specific capacity of 125.9?mAh/g at 0.1?C and a stable cycling performance, 105.2?mAh/g after 400?cycles. This unique structure could relieve the structure expansion effectively and provide more reaction sites as well as shorten the diffusion path for Li_(+) for improving electrochemical performance for LIBs.
