3D Nitrogen-Doped Graphene foam with encapsulated germanium/Nitrogen-Doped Graphene yolk-shell nanoarchitecture for high-performance flexible Li-ion battery
Nature Communications, 2017Co-Authors: Runwei Mo, David Rooney, Hui Ying YangAbstract:The development of materials for energy storage hinges on the design of electrodes with large capacity, flexibility, fast charge–discharge rate and long cycling lifetime. Here, the authors develop electrodes based on nitrogen doped Graphene with encapsulated Ge quantum dots with yolk-shell architecture.

3D Nitrogen-Doped Graphene foam with encapsulated germanium/Nitrogen-Doped Graphene yolk-shell nanoarchitecture for high-performance flexible Li-ion battery
Nature Communications, 2017Co-Authors: Runwei Mo, Kening Sun, David Rooney, Hui Ying YangAbstract:Flexible electrochemical energy storage devices have attracted extensive attention as promising power sources for the ever-growing field of flexible and wearable electronic products. However, the rational design of a novel electrode structure with a good flexibility, high capacity, fast charge–discharge rate and long cycling lifetimes remains a long-standing challenge for developing next-generation flexible energy-storage materials. Herein, we develop a facile and general approach to three-dimensional (3D) interconnected porous Nitrogen-Doped Graphene foam with encapsulated Ge quantum dot/Nitrogen-Doped Graphene yolk-shell nano architecture for high specific reversible capacity (1,220mAhg?1), long cycling capability (over 96% reversible capacity retention from the second to 1,000 cycles) and ultra-high rate performance (over 800mAhg?1 at 40 C). This work paves a way to develop the 3D interconnected Graphene-based high-capacity electrode material systems, particularly those that suffer from huge volume expansion, for the future development of high-performance flexible energy storage systems. 1

Shock-wave synthesis of multilayer Graphene and Nitrogen-Doped Graphene materials from carbonate
Carbon, 2015Co-Authors: Hao Yin, Pengwan Chen, Xing Gao, Chunxiao Xu, Yang Zhao, Qiang Zhou, Liangti QuAbstract:A method for transforming carbonate into Graphene using shock-wave loading is presented in this paper. Multilayer Graphene was synthesized by impacting mixtures of calcium carbonate and magnesium using a detonation-driven flyer. Furthermore, by adding ammonium nitrate to the reaction system, Nitrogen-Doped Graphene material was formed in a one-step shock-wave treatment. The recovered samples were characterized using various techniques such as transmission electron microscopy, Raman spectroscopy, X-ray diffraction, and X-ray photoelectron spectroscopy. The shock synthesis of Graphene materials requires a balance between the growth rate of Graphene materials and the formation rate of carbon atoms. The pressure and temperature are two important factors affecting the synthesis of Graphene materials. Shock-synthesized Nitrogen-Doped Graphene material was demonstrated to act as a metal-free electrode with an efficient electrocatalytic activity and long-term operation stability for the oxygen reduction reaction via two- and four-electron pathways in alkaline fuel cells.
