A highly efficient self-power pack system integrating supercapacitors and photovoltaics with an area-saving monolithic architecture
Autor: Byoungwook Park, Seongyu Lee, Junghwan Kim, Yun-Hwa Hwang, Kwanghee Lee, Sun Min Lee, Jae-Hyung Jang
Publikováno v: Journal of Materials Chemistry A. 5:1906-1912
Self-charging power packs (SPPs), integrating both a solar cell and energy storage capacitor (EC) into a single device, are very promising energy systems due to their multiple functions of energy harvesting and storage. Despite their promising potent

A new approach of structural and chemical modification on graphene electrodes for high-performance supercapacitors
Autor: Kwanghee Lee, Yung Ho Kahng, Yong Jae Kim, Sun Min Lee, Yun-Hwa Hwang
Publikováno v: Carbon. 100:7-15
The low energy density of graphene-based supercapacitors has been a critical bottleneck for their commercialization. In particular, the poor capacitance due to the lack of electrically porous channels and insufficient Faradaic reactions in reduced gr

SnO2 nanoparticles confined in a graphene framework for advanced anode materials
Autor: Yun-Hwa Hwang, Myoungho Pyo, Kee-Sun Sohn, Sangdeok Shim, Eun Gyoung Bae, Myoung Soo Lah, Xiaokai Song
Publikováno v: Journal of Power Sources. 240:683-690
SnO 2 nanoparticles (SNPs) entrapped in a graphene framework are synthesized for use as an anode material in Li ion batteries. A framework is prepared by covalently linking SNPs-anchored graphene oxide layers with diboronic acids. The framework provi

SnO2/Graphene Composites with Self-Assembled Alternating Oxide and Amine Layers for High Li-Storage and Excellent Stability
Autor: Eun-Gyoung Bae, S. J. Richard Prabakar, Sangdeok Shim, Kee-Sun Sohn, Myoung Soo Lah, Myoungho Pyo, Yun-Hwa Hwang, Dongwook Kim
Publikováno v: Advanced Materials. 25:3307-3312
An alternating stack (SG/GN) consisting of SnO₂-functionalized graphene oxide (SG) and amine-functionalized GO (GN) is prepared in solution. The thermally reduced SG/GN (r(SG/GN)) with decreased micro-mesopores and completely eliminated macropores,

Graphene oxide as a corrosion inhibitor for the aluminum current collector in lithium ion batteries
Autor: Myoungho Pyo, Yun-Hwa Hwang, Dong Kyu Lee, S. J. Richard Prabakar, Eun Gyoung Bae
Publikováno v: Carbon. 52:128-136
We report for the first time the use of graphene oxide (GO) as a protective coating to inhibit the corrosion of an aluminum current collector used in lithium ion batteries. We employed a simple, but effective spin-coating method for coating GO onto A
