Published: Jan. 27, 2025

This study presents the fabrication of highly conducting Au fabric electrodes using a layer-by-layer (LBL) approach and its application toward energy storage. Through ligand-exchange mechanism, alternating layers tris(2-aminoethyl)amine (TREN) gold nanoparticles (Au NPs) encapsulated with tetraoctylammonium bromide (TOABr) ligands (Au-TOABr) were deposited onto to achieve (0.12 Ω/□) at room temperature in just two LBL cycles. In contrast several existing techniques, current realizes (7-15 coating. The obtained fabrics demonstrate excellent stability against various deformations abrasions, sheet resistance remained unaltered even after multiple cycles bending, twisting, scotch tape adhesions, sandpaper abrasions. addition, prepared exhibit high robustness chemical media, highlighting their anticorrosive properties. Although showed slight increase postwashing ultrasonication tests, it was got ridden by coating thin layer biocompatible polydimethylsiloxane (PDMS) polymer. Besides enhancing adhesion NPs, PDMS offered hydrophobic surface rendering use self-cleaning applications. High-performing storage devices integrated wearable technologies are great demand. this context, here, electropolymerized polyaniline (PANI)-coated employed develop supercapacitors remarkable energy-storing capability. symmetric two-electrode configuration, device maximum areal capacitance 660 mF/cm2 power densities 58.64 μWh/cm2 22.86 mW/cm2, respectively. solid-state supercapacitor (SSD) fabricated Au/PANI-30 exhibited an 495 33 10,660 μW/cm2, method offers significant advantage over techniques offering simple room-temperature conductivity adaptability substrates ease scalability.

Rational Design of Three-Dimensional Architectures of Carbon Nanorods/Carbon Nanofibers Composite for High-Performance Supercapacitors

ACS Applied Energy Materials, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 16, 2025

Carbon nanofibers (CNFs) have important application potential in the field of supercapacitors; however, relatively low specific surface area often leads to a capacitance. Herein, N-doped carbon nanofibers/carbon nanorods (CNFs/CNRs-N) composite with an N-doping level up 8.9 atom % is designed, which shows excellent supercapacitor energy storage performance. CNFs/CNRs-N has three-dimensional porous structure, large area, and huge number active sites. Based on synergy various unique properties CNFs/CNRs-N, when used as electrode material, it capacitance value 595 F g–1.
