Mass-produced multi-walled carbon nanotube as a conducting additive on the applications for supercapacitors

Optimal amount for the best performance

Abstract

The feasibility of mass-produced multi-walled carbon nanotubes (MWNTs) as an additive for supercapacitor and its optimal addition amount was investigated by using of a practical measurement of supercapacitor. When considering rate capability (1-60 mA/cm²) for the addition amount of MWNTs at 10, 20 and 30 wt.%, the addition of 10 wt.% was no large deterioration capacitance as a function of the current density compared to no addition. Thus, the addition of 10 wt. % was optimal addition amount of MWNTs.
