Electrospun ZnFe2O4/carbon nanofibers as high-rate supercapacitor electrodes

ZnFe2O4/carbon (ZFO/C) nanofibers are prepared by electrospinning method with subsequent stabilization treatment, high temperature carbonization, and extra induced annealing for high performance supercapacitor electrodes. Previous attempts to incorporate ZFO into electrospun fibers always resulted in ZFO nanofibers without carbon or multiphase components in carbon nanofibers. In this work, the extra induced annealing is introduced, successfully...
