摘要	Supercapacitors are a promising high-power energy storage device due to highly reversible charge-storage process and long cyclic stability. However, the major limitation of supercapacitors lies in their energy density. Here, a high voltage carbon-based supercapacitor is built by using 2M CH3COONa aqueous solution as electrolyte. In three-electrode system, this paper uses the potentiostatic polarization curves to study the 1.8V high operating voltage window with the nitrogen-self-doped mesoporous carbon materials (FBNC-700) as electrode materials. In two-electrode system, the FBNC-700 displayed a specific capacitance of 111Fg(-1) at a current density of 0.5Ag(-1) in 2M CH3COONa aqueous electrolyte. The 2M CH3COONa aqueous electrolytes which can improve the energy density to 3.8 times than the 1M H2SO4 aqueous electrolyte exhibits an excellent performance. Also, following 5000cycles at a current density of 1Ag(-1), the FBNC-700 had good stability with 74.2% capacitance retention. As an aqueous electrolyte, 2M CH3COONa which has the 1.8V high operating voltage window can improve the energy density in carbon-based supercapactor.
