Rice Straw-Derived Carbon Integrated with PANI as an Electrode Material for High-performance Supercapacitor

Abstract

A novel composite electrode material has been synthesized using in-situ chemical polymerization of aniline over the surface of rice straw-derived carbon (RSC). The detailed structural characterization validates the effective incorporation of granular polyaniline (PANI) over the RSC surface. The supercapacitor performance of the RSC@PANI electrode was systematically investigated and achieved as high as specific capacitance of 408 Fg-1 at a current density of 1 Ag-1. Moreover, RSC@PANI shows 93% capacitance retention after 1000 cycles at a current density 10 Ag-1. Apart from its outstanding electrochemical performance, the resulting RSC@PANI electrode exhibits exceptional characteristics such as scalability and lightweight properties. This study contributes valuable insights into the synthesis and characterization of RSC@PANI as a promising electrode material for supercapacitors.
