Abstract
Twodimensional large area graphene/carbon nanotubes LAG–CNTs nanocomposites as additional material for carbonbased electric double layer capacitor EDLC performance have been fabricated by using chemical vapor deposition method The asprepared LAG–CNTs are characterized with Raman field emission scanning electron microscope transmission electron microscope highresolution transmission electron microscopy and atomic force microscopy images Finally EDLC electrodes based with high surface area activated carbon YP50F and LAG–CNTs were fabricated by a facile step The prepared electrodes 8LAG–CNTs/AC exhibit a specific capacitance of 155 F cc−1 at 05 mA cm−2 excellent cycling stability 961 retention after 100 cycles and high rate capability These excellent capacitive performances may make the asprepared nanocomposites as conductive material for preparation of promising electrode materials of EDLC
