Functional Carbon Nanotube/Mesoporous Carbon/MnO₂ Hybrid Network for High‐Performance Supercapacitors

Abstract

A functional carbon nanotube/mesoporous carbon/MnO 2 hybrid 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 MnO 2 with the good conductivity of the carbon nanotube/mesoporous carbon networks. Such composite shows great potential to be used as electrodes for supercapacitors.
