The porous Fe3O4/C microbelts (FCBs) were synthesized by simple electrospinning method, combined with carbonization of the precursor microbelts at high temperature in N-2 flow. Compared with alpha-Fe2O3 microbelt, the FCBs show better cyclic performance. The high capacity of 710 mA h g(-1) is still maintained after 50 cycles. The excellent performance of PCBs in lithium-ion batteries can be attributed to the highly stable porous belt structure of FCBs and to the substantial structure carbon matrix surrounded Fe3O4 nanoparticles. The synthesis method is simple, cheap, and green and could be extended to fabricate other carbon composites.
