成果介绍

本发明涉及超级电容器电极材料技术领域。具体公开一种多孔碳材料的制备方法、超级电容器电极和超级电容器。所述制备方法包括将尿素与柠檬酸溶于溶剂中，获得前驱体溶液：将前驱体溶液进行烘干处理，得到前驱体材料；将前驱体材料破碎成前驱体粉末；以(2～10)℃/min的升温速率将前驱体粉末升温至(700～1000)℃，使前驱体粉末碳化，得到形貌规则的碳材料；在保护气氛下将碳材料与活化剂混合升温至(360～400)℃保温(20～30)min，再升温至(600～800)℃保温(60～120)min，得到多孔碳材料。本发明制备出的多孔碳材料性能稳定，比表面积大且表面含氮官能团，适合作为超级电容器电极材料。
