Facile Route

A functional carbon nanotube/mesoporous carbon/MnO2hybrid network has been developed successfully through a facile route. The resulting composites exhibited a high specific capacitance of 351 F/g at 1 A g−1, with intriguing charge/discharge rate performance and cycling stability due to a synergistic combination of large surface area and excellent electron-transport capabilities of MnO2with the good conductivity of the carbon nanotube/mesoporous carbon networks. Such composite shows great potential to be used as electrodes for supercapacitors.

Negative Electrode Material

Mesoporous C@FexSy composite as a negative electrode for supercapacitors was synthesized via a one-step hydrothermal treatment followed by an electrodeposition process and its electrochemical properties were studied. Compared with bare carbon sphere, the electrochemical performance of C@FexSy composite was significantly improved, with a high specific capacitance (267.45 F/g), good rate performance (201.08 F/g at 2.5 A/g), and superior cycling stability (almost no capacitance degradation after 1000 cycles). The results show that the obtained C@FexSy composite is a promising negative electrode material for supercapacitors
