Fabrication of NiFe2O4@CoFe2O4 core-shell nanofibers for high-performance supercapacitors
NiFe _2 O _4 @CoFe _2 O _4 core–shell nanofibers were prepared by the co-electrospinning method. The prepared core–shell NiFe _2 O _4 @CoFe _2 O _4 nanofibers electrode has the specific capacitance of 480 Fg ^−1 at a current density of 1Ag ^−1 . After being cycled 2000 times at a current density of...

description | NiFe _2 O _4 @CoFe _2 O _4 core–shell nanofibers were prepared by the co-electrospinning method. The prepared core–shell NiFe _2 O _4 @CoFe _2 O _4 nanofibers electrode has the specific capacitance of 480 Fg ^−1 at a current density of 1Ag ^−1 . After being cycled 2000 times at a current density of 5Ag ^−1 , the capacity of NiFe _2 O _4 @CoFe _2 O _4 core–shell nanofibers remained 87%. The electrochemical performance of the supercapacitor is improved by the synergistic action of the multi-metal and indicates that core/shell NiFe _2 O _4 @CoFe _2 O _4 nanofibers are promising materials. |
