Abstract

We report on the synthesis and electrochemical properties of multi-walled
carbon nanotubes (MWCNTs) for supercapacitor devices. Freestanding vertically-aligned MWCNTs and MWCNT powder were grown concomitantly in a
one-step chemical vapour deposition process. Samples were characterized by
scanning and transmission electron microscopies and Fourier transform infrared
and Raman spectroscopies. At similar film thicknesses and surface
areas, the freestanding MWCNT electrodes showed higher electrochemical
capacitance and gravimetric specific energy and power than the randomlypacked
nanoparticle-based electrodes. This suggests that more ordered electrode
film architectures facilitate faster electron and ion transport during the
charge–discharge processes. Energy storage and supply or supercapacitor
devices made from these materials could bridge the gap between rechargeable
batteries and conventional high-power electrostatic capacitors.
