摘要：

Nickel oxide (NiO) nano-structures were synthesized on random carbon nanotubes (CNTs) growing on a carbon cloth substrate processed using vacuum annealing and oxygen plasma treatment for the electric double layer capacitor electrode application (EDLC). From the electrochemical measurement analytical results the NiO nano-structure/CNT composite electrode with carbon cloth substrate exhibits low internal resistance features. The specific NiO/CNTs/carbon cloth electrode capacitance can reach up to 162.41 F/g in contrast with 53.75 F/g for the CNTs/carbon cloth electrode in 1 M KOH solution. These results indicate that NiO nano-structures formed onto CNTs/carbon cloth electrodes are suitable materials for EDLC applications. (C) 2012 Elsevier Ltd. All rights reserved.
