二维（2D）石墨烯材料由于其由sp2-cabon网络衍生的高导电性而作为超级电容器的有前途的电极材料引起了极大的兴趣。然而，这些2D层状材料倾向于彼此堆叠，这大大减少了表面积。在这里，我们报告了具有大表面积的高石墨化大孔碳的设计，适用于超级电容器应用。当与其他碳材料（如无定形大孔碳、活性炭、石墨或剥离的石墨烯氧化物）进行基准测试时，我们的石墨大孔碳显示出上级电容。
Two‐dimensional (2D) graphene materials have attracted great interest as promising electrode materials in supercapacitors due to their high electrical conductivity derived fromsp2‐cabon network. These 2D layered materials, however, tend to stack with each other, which largely decreases the surface area. Here we report the design of highly graphitic macroporous carbon with large surface area suitable for supercapacitor applications. When benchmarked with other carbon materials, such as amorphous macroporous carbon, activated carbon, graphite or exfoliated graphene oxides, our graphitic macroporous carbon show superior capacitance.
