Evidence of Graphitic AB Stacking Order of Graphite Oxides
Hae Kyung Jeong,Yun Pyo Lee,Rob J. W. E. Lahaye,Min-Ho Park,Kay Hyeok An,Ick Jun Kim,Cheol-Woong Yang,Chong Yun Park,Rodney S. Ruoff,Young Hee Lee +9 more
TL;DR: Graphite oxide samples were prepared by a simplified Brodie method and AB stacking of the layers in the GO was inferred from an electron diffraction study, which suggests that carboxyl and alkyl groups are at the edges of the flakes of graphite oxide.
Journal ArticleDOI
Electrochemical Properties of High-Power Supercapacitors Using Single-Walled Carbon Nanotube Electrodes
Kay Hyeok An,WonJin Kim,Young Soo Park,Jeong-Mi Moon,Dong Jae Bae,Seong Chu Lim,Young Seak Lee,Young Hee Lee +7 more
TL;DR: In this paper, the authors investigated the key factors determining the performance of supercapacitors constructed using single-walled carbon nanotube (SWNT) electrodes and found a maximum specific capacitance of 180 F/g and a measured power density of 20 kW/kg at energy densities in the range from 7 to 6.5 Wh/kg in a solution of 7.5 N KOH.

Journal ArticleDOI
High-Capacitance Supercapacitor Using a Nanocomposite Electrode of Single-Walled Carbon Nanotube and Polypyrrole
TL;DR: In this article, a nanocomposite electrode of single-walled carbon nanotube (SWNT) and polypyrrole (Ppy) is fabricated to improve the specific capacitance of the supercapacitor.
Journal ArticleDOI
Nickel oxide/carbon nanotubes nanocomposite for electrochemical capacitance
TL;DR: In this paper, the authors have fabricated supercapacitor electrodes with nickel oxide (NiO)/carbon nanotubes (CNTs) nanocomposite formed by a simple chemical precipitation method.
