摘要：

采用干法电极制备工艺成功制备了活性石墨烯/活性炭复合电极片，分别用扣式电容器和软包电容器考察活性石墨烯/活性炭复合电极的电化学性能。综合结果表明，复合电极中活性石墨烯的含量为10%（质量分数）较为合适，相较于纯活性炭电极，比容量提高了10.8%。本工作验证了活性石墨烯材料在商用超级电容器中的适用性，证实了活性石墨烯是一种非常具有实际应用价值的电极材料。但目前，活性石墨烯并未真正产业化，其成本远高于商用活性炭。在未来，如何解决活性石墨烯工程制备技术难题和降低成本是材料产业界亟待解决的难题。

Abstract:

Activated graphene/activated carbon composite electrodes were successfully prepared by the method of dry method of electrode preparation. The electrochemical performance of activated graphene/activated carbon electrodes was investigated using coin cell supercapacitor and soft package supercapacitor, respectively. Comprehensive results show that the activated graphene content of 10% (weight ratio) in composite is relatively reasonable. Compared to activated carbon electrode, the specific capacitance of 10% (weight ratio) activated graphene/activated carbon composite electrode increases by 10.8%. This work verified the applicability of activated graphene material in the commercial supercapacitor, and confirmed that the activated graphene is a kind of electrode material with high practical application value. But by now, the activated graphene has not really industrialization, its cost is much higher than that of commercial activated carbon. In the future, how to solve the engineering technical problem of activated carbon and reduce its cost are the urgent problems to be solved by the material industry.
