Title: Enhanced electrochemical performance of an electrospun carbon/MoO2 composite nanofiber membrane as self-standing anodes for lithium-ion batteries

Abstract

Highlights: • Flexible C/MoO{sub 2} NFM was prepared by electrospinning and controlled heat treatment. • C/MoO{sub 2} NFM was used directly as self-standing and binder-free anodes for LIBs. • The electrode exhibits good capacity retention, rate performance and cyclability. • A high reversible capacity (811 mAh g{sup –1}) is obtained at 100 mA g{sup –1} after 100 cycles. • The possible mechanisms of the superior electrochemical performance are discussed. - Abstract: A flexible carbon nanofiber membrane (NFM) containing uniformly dispersed MoO{sub 2} nanoparticles is facilely fabricated via electrospinning and subsequent controlled reduction-carbonization. This NFM is used directly as a binder-free anode in lithium-ion batteries (LIBs). The self-standing carbon/MoO{sub 2} (C/MoO{sub 2}) NFM electrode has a good capacity retention, a satisfactory rate capability and a high reversible capacity of 811 mAh g{sup –1} after 100 cycles at a current density of 100 mA g{sup –1}, which is superior to most other MoO{sub 2}-based anodes. The superior electrochemical properties of the resultant C/MoO{sub 2} NFM are attributed to the cooperative effects from the excellent conductivity of the carbon nanofiber matrix, the high electrochemical performance of MoO{sub 2}, the unique one-dimensional nanofiber structure and the three-dimensional porous network structure. The present C/MoO{sub 2}more » NFM may be an attractive candidate as an anode material for LIBs.« less
