	1	Increased working voltage of hexamine-coated porous carbon for supercapacitors显示文摘Highly porous carbon, both unmodified and hexamine-coated on the pore surfaces, is tested at high working voltages in organic electrolyte for supercapacitors in order to enhance the energy density and power density.Sol–gel processing allows for excellent control of the porous structure and chemical composition of carbon,resulting in a material with high surface area and a low level of impurities. This porous carbon can be modified using a simple solution-based method to enhance capacitance. Increasing the working voltage from 2.0 to 3.0 V significantly improves performance for both unmodified and hexamine-coated carbon. The energy density and power density increase at higher working voltage, and under certain conditions, the capacitance increases as well.Cyclic stability is also investigated, with hexamine-coated carbon retaining more of its initial capacitance than unmodified carbon at all working voltages.

	2	比较多孔碳的表面和体相掺氮改性对超级电容器性能的影响(英文)显示文摘溶胶-凝胶法制备的高孔隙度多孔碳材料可通过简单溶液法用氮进行改性从而增加电容.氮的引入可采用表面氮改性通过引入六亚甲基四胺涂层再热解分解,或在碳网结构中引入氮两种方式.本文对两种材料的性能和电化学行为进行测量并与未改性的多孔碳进行比较.在碳网结构中的氮表现出增强的导电性,而表面进行氮改性的多孔碳对于增强电容更有效.氮改性还可以通过减少扩散电阻和电荷转移电阻,进而增强超级电容器在高倍率的充放电性能.
