摘　　要：碳纳米管材料作为一种先进碳材料,具有十分良好的导电性,但是其比表面积和比容量比较低。氮掺杂的碳材料用于超级电容器的容量高、比表面积较大,但是其导电性较差。因此,考虑将二者相结合,将氮碳掺杂的碳材料分别负载在碳纳米管的内部与外部,研究其对超级电容器储能性能的影响。结果表明,碳纳米管外负载氮掺杂的碳材料表现出较好的电化学活性,包括高的容量和优异的循环性能。As one type of advanced carbon material,carbon nanotubes(CNTs)owns very good electrical conductivity,but its specific surface area is relatively low,leading to a poor supercapacitive performance.While,as electrode for supercapacitor,nitrogen-doped carbon material has a large surface area and exhibits a high capacity but suffers from poor conductivity.Hererin,a composite carbon materials combined these two carbon-based materials was fabricated,in which the nitrogen-carbon doped carbon material were respectively supported inside and outside CNTs.The electrochemical properties of the derived two carbons were systematically studied.The results shown that the nitrogen-doped carbon supported outside CNTs exhibited good electrochemical activity including high capacitance and superior cycling stability.
