MWCNT/AC Electrode Synthesis on Supercapacitor Performance with NaCl Electrolyte

Abstract

The increase in the use of electronics requires high enough energy storage so that the use of supercapacitors is very necessary. The solution is obtained by the presence of carbon-based electrode material (MWCNT / AC). Our research used MWCNT and AC because it has high conductivity using the doctor blade method and a three-electrode system. Electrochemical analysis was performed by adding electrolyte NaCl and tested with CV and EIS. Electrolyte concentration of 2 M NaCl which has a high value of 11.1559 F / g with an energy density of 1580.58 Wh / kg and a power density of 1138017 W / kg. The resistor, capacitor and CPE values in the EIS test are generated respectively R=3.1234 Ω, C=0.0004 F, and Z_CPE=0.0005 F⁄s.
