摘要

The development of high-capacitance electrode materials for use in energy storage, particularly supercapacitors, remains difficult. Several types of material have been documented; however, carbon-based electrodes are the most reliable because of their high stability, high conductivity, and high energy density. However, owing to the nature of carbon compounds, general carbon materials are not suitable for stand-alone applications. Electrospun carbon nanofibers (CNFs) can bridge this gap, but they have poor capacitance and energy density on their own. To address this issue, polyaniline (PANI) was chosen as a companion for this comparative study. Our study revealed that CNFs attained the highest specific capacitance of 408 F/g at a current density of 1 A/g with the highest energy density of 14.16 Wh/kg. PANI showed a specific capacitance of 754 f/g at a current density of 1 A/g at the highest energy density of 26.17 Wh/kg.
