Carbon-Based Electrodes for Supercapacitors and Electrochemical Sensors
This community develops carbon-rich electrode materials, primarily graphene derivatives and porous carbons, to build high-performance supercapacitors for energy storage and sensitive electrochemical sensors for detecting chemical and biological compounds.
The work centers on synthesizing and modifying graphene oxide, reduced graphene, carbon nanotubes, and activated carbon to create electrodes with specific surface areas and conductivities. A major strand focuses on asymmetric and hybrid supercapacitors, combining these carbon structures with metal oxides or conducting polymers to increase energy density. A parallel strand applies these same carbon matrices to electrochemical sensing, using them as substrates to detect analytes like hydrogen peroxide, pharmaceuticals, and biomarkers with high sensitivity. The recurring methods involve facile synthesis, composite formation, and surface modification to enhance electrochemical performance in both storage and detection applications.
The largest share of the community's output is found in Carbon research, accounting for 7.4% of all carbon-related papers, with 61,683 papers in this group. Nickel and Cobalt also contribute significantly, representing 3.0% and 3.3% of their respective element research, respectively.
The community comprises 92,255 papers, publishing most frequently in Carbon, Electrochimica Acta, and the Journal of Energy Storage.
Recent work continues to explore hybrid "supercapattery" devices that combine battery and supercapacitor electrode functionalities, as well as the development of wearable aptamer-based sensors for continuous in vivo biomarker monitoring and sustainable carbon cloth electrodes for zinc-ion capacitors.
