Biomass-derived Nanoporous Carbon-based Electrodes for High-performance Symmetric Supercapacitor
J. Environ. Nanotechnol., Volume 8, No 4 (2019) pp. 33-37
Abstract
The high-performance symmetric supercapacitor electrodes were fabricated using peanut shell-activated porous carbon, synthesized by chemical activation method. The textural and surface morphologies were analyzed. The electrochemical studies of fabricated electrodes were carried out by 6 M KOH as an aqueous electrolyte using two electrodes system. From charge-discharge process, gravimetric capacitance and volumetric capacitance values were calculated such as 160 Fg-1 and 116.8 Fcm-3 at a current density of 1 Ag-1 in 6 M KOH solution. Energy density and power density values were calculated as 5.5 Whkg-1 for 1 Ag-1 and 4 kWkg-1 for 10 Ag-1, respectively. This electrode has excellent cyclic stability and has revealed 80% capacitance retention even after 8,000 charge/discharge cycles at 1 Ag-1. The result clearly demonstrated that the natural resource of specific biomass could be an economic and eco-friendly alternative raw material for supercapacitor electrodes with efficient volumetric energy and power densities.
