Facile synthesis of activated carbon/carbon nanotubes compound for supercapacitor application

---

a b s t r a c t
A large number of carbon nanotubes (CNTs) have been produced commingled in activated mesocarbon
microbeads (AMCMBs) activated by potassium hydroxide in a stainless steel container at 900 ◦C, in which
an especial buried-protection method with petroleum coke powders was used to protecting the product
during activation. The CNTs were found to be about 50nmin diameter and characteristic length more than
10m. In addition, the AMCMBs/CNTs compound when used for electrode material of electrochemical
double-layer capacitors exhibited a specific capacitance of 243 F g−1 in 6M KOH aqueous solution.
Keywords:Carbon nanotubes, Mesocarbon microbeads, Chemical activation, Supercapacitors
