Nanoporous Activated Carbon and Multi-walled Carbon Nanotubes from Renewable Botanical Hydrocarbons and their Impact on Efficiency of Supercapacitor Performance
J. Environ. Nanotechnol., Volume 9, No 1 (2020) pp. 01-04
Abstract
Highly activated carbon and Multi-walled carbon nanotubes (MWCNTs) are preferable materials for supercapacitor electrode. Activated Carbon was prepared from Pongamia pinnata shell by Chemical Activation process and MWNTs were prepared from Pongamia pinnata oil by Spray pyrolysis method, respectively. The electrochemical capacitor has been assembled with Multi-walled carbon nanotubes/Graphene composites as negative electrode and activated carbon as positive electrode with 6 M KOH as an aqueous electrolyte. The charge-discharge performance of fabricated electrodes was satisfactory for energy storage applications. It has to be improved by the addition of MWCNTs in anodes. It can be executed with a specific capacitance of 148 Fg-1 at a current density of 0.5 Ag-1. The maximum energy density and power density were up to 5.1 Whkg-1 at 0.5 Ag-1 and 5.0 kWkg-1 at 10 Ag-1, respectively. The galvano-static charge-discharge cycling studies have revealed the excellent capacity retention of 81% even after 4000 cycles. The unique fabrication strategy for the two-electrode SC assembly with highly conducting and stable-natured carbon nanomaterials expand the arms of energy storage devices.
