题目：Ultrahigh volumetric capacitance and cyclic stability of fluorine and nitrogen co-doped carbon microspheres (欢迎达人点评这篇Nature Communications的新颖之处) 作者：Junshuang Zhou1, Jie Lian2, Li Hou1, Junchuan Zhang1, Huiyang Gou3, Meirong Xia1, Yufeng Zhao1,Timothy A. Strobel3, Lu Tao1 & Faming Gao1 1 Key Laboratory of Applied Chemistry, College of Environmental and Chemical Engineering, Yanshan University, Qinhuangdao 066004, China. 2 Department of Mechanical, Aerospace, and Nuclear Engineering, Rensselaer Polytechnic Institute, Troy, New York 12180, USA. 3 Geophysical Laboratory, Carnegie Institution of Washington, Washington DC 20015, USA. Correspondence and requests for materials should be addressed to F.G. (email: fmgao@ysu.edu.cn). 摘要：Highly porous nanostructures with large surface areas are typically employed for electrical double-layer capacitors to improve gravimetric energy storage capacity; however, high surface area carbon-based electrodes result in poor volumetric capacitance because of the low packing density of porous materials. Here, we demonstrate ultrahigh volumetric capacitance of 521 F cm-3 in aqueous electrolytes for non-porous carbon microsphere electrodes co-doped with fluorine and nitrogen synthesized by low-temperature solvothermal route, rivaling expensive RuO2 or MnO2 pseudo-capacitors. The new electrodes also exhibit excellent cyclic stability without capacitance loss after 10,000 cycles in both acidic and basic electrolytes at a high charge current of 5 A g-1. This work provides a new approach for designing high-performance electrodes with exceptional volumetric capacitance with high mass loadings and charge rates for long-lived electrochemical energy storage systems.  1.jpg  2.jpg |
