Carbon-based materials as supercapacitor electrodes.
This tutorial review provides a brief summary of recent research progress on carbon-based electrode materials for supercapacitors, as well as the importance of electrolytes in the development of
Capacitance of carbon-based electrical double-layer capacitors.
TLDR
The electrical double-layer capacitance in one to five-layer graphene is measured and it is found that the capacitances are suppressed near neutrality, and are anomalously enhanced for thicknesses below a few layers.
Layered graphene oxide nanostructures with sandwiched conducting polymers as supercapacitor electrodes.
TLDR
A graphene oxide-polypyrrole composite prepared from this approach exhibited an excellent electrocapacitive performance with a high specific capacitance over 500 F g(-1).
Improved electrical conductivity of graphene films integrated with metal nanowires.
TLDR
Graphene/NW films with a sheet resistance comparable to that of the intrinsic resistance of graphene have been obtained and tested as a transparent electrode replacing indium tin oxide films in electrochromic (EC) devices.
Highly conductive and porous activated reduced graphene oxide films for high-power supercapacitors.
TLDR
These free-standing thin films provide a route to simplify the electrode-manufacturing process by eliminating conducting additives and binders and are the highest values achieved while simultaneously maintaining excellent specific capacitances and energy densities for graphene materials.
Photocatalytic degradation of dyes over graphene-gold nanocomposites under visible light irradiation.
Graphene modified with gold nanoparticles displayed an excellent visible-light photocatalytic performance in degrading dyes in water.
Nanoporous Ni(OH)2 thin film on 3D Ultrathin-graphite foam for asymmetric supercapacitor.
TLDR
Nanoporous nickel hydroxide thin film was grown on the surface of ultrathin-graphite foam (UGF) via a hydrothermal reaction and used as the electrode in a supercapacitor without the need for addition of either binder or metal-based current collector.
Generation of B-doped graphene nanoplatelets using a solution process and their supercapacitor applications.
TLDR
Two- and three-electrode cell measurements showed that energy storage in the B-rG-O supercapacitors was contributed by ion adsorption on the surface of the nanoplatelets in addition to electrochemical redox reactions.
Graphene‐Encapsulated Si on Ultrathin‐Graphite Foam as Anode for High Capacity Lithium‐Ion Batteries
TLDR
The Si/graphene/UGF composite presents excellent stability and relatively high overall capacity when tested as an anode for rechargeable lithium ion batteries.
Pillaring chemically exfoliated graphene oxide with carbon nanotubes for photocatalytic degradation of dyes under visible light irradiation.
TLDR
The CNT-pillared RGO composite materials exhibited an excellent visible light photocatalytic performance in degrading dye Rhodamine B because of the unique porous structure and the exceptional electron transfer property of graphene.
