Asymmetric Supercapacitors Based on Graphene/MnO2 Nanospheres and Graphene/MoO3 Nanosheets with High Energy Density
Jian Chang,Meihua Jin,Fei Yao,Tae Hyung Kim,Viet Thong Le,Hongyan Yue,Hongyan Yue,Fethullah Güneş,Bing Li,Arunabha Ghosh,Sishen Xie,Young Hee Lee +11 more
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
Fei Yao,Fei Yao,Fethullah Güneş,Huy Q. Ta,Seung Mi Lee,Seung Jin Chae,Kyeu Yoon Sheem,Costel Sorin Cojocaru,Si Shen Xie,Young Hee Lee +9 more
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.
Duy Tho Pham,Tae Hoon Lee,Dinh Hoa Luong,Fei Yao,Arunabha Ghosh,Viet Thong Le,Tae Hyung Kim,Bing Li,Jian Chang,Young Hee Lee +9 more
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.
Hong Yan Yue,Shuo Huang,Jian Chang,Chaejeong Heo,Fei Yao,Subash Adhikari,Fethullah Güneş,Lichun Liu,Tae Hoon Lee,Eung Seok Oh,Bing Li,Jian Jiao Zhang,Ta Quang Huy,Nguyen Van Luan,Young Hee Lee +14 more
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.
