Abstract:

This paper summarized the progress of supercapacitors electrode materials based on carbon nanotubes and their composites. The capacitor′s characteristics will be effectively improved when carbon nanotubes are modified or the carbon nanotubes composite with other materials. The article focuses on the recent development of the supercapacitor electrode materials using carbon nanotubes with the techniques of modification, activation, and dispersion, as well as nanotubes-transition metal oxide composites, carbon nanotubes-conductive polymer composites, and carbon nanotubes-graphene composites.

Key words: carbon nanotubes, supercapacitors, composites
