Porous α-Fe(2)O(3)@C Nanowire Arrays as Flexible Supercapacitors Electrode Materials with Excellent Electrochemical Performances

Porous α-Fe(2)O(3) nanowire arrays coated with a layer of carbon shell have been prepared by a simple hydrothermal route. The as-synthesized products show an excellent electrochemical performance with high specific capacitance and good cycling life after 9000 cycles. A solid state asymmetric superca...

description Porous α-Fe(2)O(3) nanowire arrays coated with a layer of carbon shell have been prepared by a simple hydrothermal route. The as-synthesized products show an excellent electrochemical performance with high specific capacitance and good cycling life after 9000 cycles. A solid state asymmetric supercapacitor (ASC) with a 2 V operation voltage window has been assembled by porous α-Fe(2)O(3)/C nanowire arrays as the anode materials, and MnO(2) nanosheets as the cathode materials, which gives rise to a maximum energy density of 30.625 Wh kg(−1)and a maximum power density of 5000 W kg(−1) with an excellent cycling performance of 82% retention after 10,000 cycles.
