To balance the performance in specific surface area and electrical conductivity, ordered sheets of graphene aerogels were induced into porous carbon foam for supercapacitors with enhanced specific capacitance. Systematic investigations into morphology, structure and electrochemical properties confirmed that the introduction of graphene aerogels can effectively make specific surface area to increase, however, the declined resistance is neither due to electrolyte diffusion nor charge transfer, which gave rise to the improvement of electrochemical performance by 55.3% with a great specific capacitance of 210.5 F $$\hbox {g}^{\mathrm {-1}}$$ g - 1 at the current density of 0.5 A $$\hbox {g}^{\mathrm {-1}}$$ g - 1 compared to that of carbon foam.

3D互连石墨烯气凝胶/碳泡沫网络在超级电容器的比表面积和电导率方面具有平衡的性能

为了平衡比表面积和电导率的性能，将有序的石墨烯气凝胶片引入多孔碳泡沫中，用于具有增强的比电容的超级电容器。对形貌、结构和电化学性能的系统研究证实，石墨烯气凝胶的引入可以有效地增加比表面积，但电阻的下降既不是由于电解质扩散也不是由于电荷转移，这导致电化学性能的提高55.3%，比电容为 210.5 F $$\hbox {g}^{\mathrm {-1}}$$ g - 1 在电流密度为 0.5 A $$\hbox {g}^{\mathrm { -1}}$$ g - 1 与碳泡沫相比。
