green Energy & Environment 2020年第1期5卷 69-75页

作者： Zhiwei Lu Xiaochao Xu Yujuan Chen Xiaohui Wang Li Sun Kelei Zhuo collaborative innovation Center of henan province for green manufacturing of fine chemicals Key Laboratory of Green Chemical Media and ReactionsMinistry of Education School of Chemistry and Chemical Engineering Henan Normal University

Supercapacitors with unique performance have been widely utilized in many fields. Herein, we report a nitrogen and sulfur co-doped graphene aerogel(N/S-GA-2) prepared using a low toxic precursor for high-performance supercapacitors. The as-obtained material possesses a hierarchically porous structure and a large number of electrochemical active sites. At a current density of 1 Ag^-1, the specific capacitance of the N/S-GA-2 for supercapacitors with the ionic liquid as the electrolyte is 169.4 Fg^-1, and the corresponding energy density is 84.5 Wh kg^-*** a power density of 8.9 k W kg^-1, the energy density can reach up to 75.7 Wh kg^-1, showing that the N/S-GA-2 has an excellent electrochemical performance. Consequently, the N/S-GA-2 can be used as a promising candidate of electrode materials for supercapacitors with high power density and high energy density.
