摘要

Carbon nanocapule (CNC)@MnO₂ core-shell particles are prepared with a reaction of KMnO4 with CNC at 90°C. Birnessite-type MnO₂ nanoflakes are grown on CNC seeds, resulting in CNC@MnO₂ particles with a petal-like structure. The electrochemical characteristics of the prepared materials show that the highest specific capacitance (163 Fg^-1) was obtained with a scan rate of 2 mVs^-1 in 1 M Na₂SO ₄. In addition, the synthesized material has superior cycling stability. The capacitance retains 97.8% of itsinitial value after 5000 cycles with a scan rate of 100 mVs^-1.
