Recently, carbon nanomaterials are attractive for various energy storage applications due to the advantages derived from their high surface to volume ratio and stable energy storage mechanism. However, previous fabrication process of carbon nanomaterial is complicated and exhibits low productivity. Here we report the demonstration of highly porous 1D carbon nanotubes for electrode materials of supercapacitors using dual-nozzle co-electrospinning technique. The porous carbon nanotube electrode showed excellent rate capability owing to the small pores in the carbon structure enlarging active surface area between carbon and ions of electrolyte.
