Abstract
In this paper, carbon aerogels (CAs)/reduced graphene oxide (RGO) composite films were fabricated and used as electrodes for supercapacitors. The electrochemical performances of the composite electrodes with different RGO content were evaluated through cyclic voltammetry, electrochemical impedance spectrometry and chronopotentiometry tests. The results show that the incorporation of RGO into CAs can improve the capacitive performance of the composite electrodes due to a synergistic effect between them. Compared with pure CAs and RGO, CAs/RGO composite with 90:10 weight ratio of CAs to RGO exhibits a maximum specific capacitance of 157Â F/g, indicating that CAs/RGO composite should be a promising candidate as electrode material for supercapacitors.
