Abstract
This paper in concerned with the electrochemical properties for supercapacitor of composition with variation of super P/MWCNTs(multi-walled carbon nanotubes) contents. Electrochemical properties of the super P/MWCNTs were measured by cyclic voltammetry at the scan rates of 0.5 mV/s is $TEABF_4$(tetra-ethyl-ammonium-tetra-fluoro-borate) as electrolytes. As a result, the composition for 6 wt% content of MWCNTs led to an increase of capacitance, but DC resistance were decreased. It was found that the content and dispersion appearance of MWCNTs was attributed to the increase in capacitance and lower DC resistance.
