Journal ArticleDOI

Asymmetric Supercapacitors Based on Graphene/MnO2 Nanospheres and Graphene/MoO3 Nanosheets with High Energy Density

TL;DR: In this paper, a self-assembled reduced graphene oxide (RGO)/MnO2/GrMoO(2) composite was used as a positive electrode and a RGO/MoO3 composite as a negative electrode in safe aqueous Na2SO4 electrolyte.
Journal ArticleDOI

Diffusion Mechanism of Lithium Ion through Basal Plane of Layered Graphene

TL;DR: D density functional theory calculations demonstrate that divacancies and higher order defects have reasonable diffusion barrier heights allowing lithium diffusion through the basal plane but neither monovacancies nor Stone-Wales defect.
Journal ArticleDOI

Carbon nanotube-bridged graphene 3D building blocks for ultrafast compact supercapacitors.

TL;DR: The synthesis of carbon nanotube (CNT)-bridged graphene 3D building blocks via the Coulombic interaction between positively charged CNTs grafted by cationic surfactants and negatively charged graphene oxide sheets, followed by KOH activation is reported.
Journal ArticleDOI

ZnO nanowire arrays on 3D hierachical graphene foam: biomarker detection of Parkinson's disease.

TL;DR: In this paper, vertically aligned ZnO nanowire arrays (ZnO NWAs) were fabricated on 3D graphene foam (GF) and used to selectively detect uric acid (UA), dopamine (DA), and ascorbic acid(AA) by a differential pulse voltammetry method.
Journal ArticleDOI

Carbon‐Based Materials for Lithium‐Ion Batteries, Electrochemical Capacitors, and Their Hybrid Devices

TL;DR: It is illustrated that relaxation time, which is closely related to ion diffusion, can be extracted from Nyquist plots and compared between lithium-ion batteries and electrochemical capacitors, and the influence of cell conductivity, electrode/electrolyte interface, and ion diffusion on impedance performance.
