Enhanced Supercapacitor Performance Through the Synergistic Effects of a Biomass-Derived Activated Carbon and Electrochemically Deposited Polyaniline Composite
Materials Proceedings(2024)
摘要
This research delves into asymmetric supercapacitor (ASC) design, utilizing activated carbon from bamboo poles (AC) and electrodeposited polyaniline (PANI) on nickel foam (NF) as key active components. The composite electrode formed from AC and PANI exhibited enhanced electrochemical attributes in various electrochemical configurations. The specified ASC, PANI@AC/NF//AC/NF, demonstrated a potential of 1.8 V. Impressively, it reached an areal capacitance measuring 423 mF/cm2, coupled with an energy density of 190 µWh/cm2 at a power density of 900 µW/cm2, and maintained ~82% capacitance after 5000 GCD cycles. Notably, our developed ASC presents outstanding research potential for scholars and scientists.
