Abstract
Disclosed are carbon nanotubes and a method for manufacturing the same. Advantageously, the method provides a high yield of potato or sphere-shaped non-bundled carbon nanotubes having a bulk density of 80 to 250 kg/m, an ellipticity of 0.9 to 1.0 and a particle diameter distribution (Dcnt) of 0.5 to 1.0 using a two-component carbon nanotube catalyst comprising a catalyst component and an active component.
