The AMJ-3//AMJ-3-3.2 electrode delivered an energy density of 7.1 W h Kg -1 at a power density of 5.4 W Kg -1 . In order to obtain high energy density, the AMJ-3 supercapacitor performance was further evaluated in an aqueous electrolyte of 1 M Na2SO4, due to the fact that Na2SO4 aqueous solutions have a balance of H + and OH -as well as strong solvation of both Na + and SO4 2-, that often results in a high decomposition voltage upto 2 V. Based on the total mass of the active materials of the two assemble electrodes, the AMJ-3//AMJ-3-3.2 exhibited a high energy density of 24 W h Kg -1 at the power density of 533 W Kg -1 . The symmetric supercapacitor electrode could able to deliver a high-power density of 107 kW Kg - within 0.49 s. In addition, the AMJ-3//AMJ-3 electrode with various mass loading of 8, 16, and 24 mg cm -2 were fabricated and tested in 1 M Na2SO4, and resulted in the energy density of 16.2, 11.0, and 89 W h Kg -1 , respectively. The areal energy density of AMJ-3//AMJ-3 increased from 0.08 to 0.21 mW h cm -2 , while increasing the mass loading of active materials from 3.2 to 24 mg cm -2 (Fig. ), and also displayed high stability of 99.7% after 200000 cycles at a current density of 20 A g -1 . multi-level micro-meso-macro porous structure with abundant N/O functionalities. The XPS results displayed that, higher temperatures lead to the decrement of N/O contents from 4.59/12.20 at% to 1.99/5.76 at%. The electrochemical performances were suited in a threeelectrode using 1 M KOH/H2SO4, and NOC700 delivered the maximum gravimetric capacitance of 311 F g -1 at 1 A g -1 , with a pseudocapacitive contribution of 37%, and the capacitance retention of 66% in KOH, and 69% in H2SO4 at 10 A g -1 . The practical applications of NOC700 electrodes were studied by assembling them into a symmetric cell with the redoxactive hybrid electrolyte H2SO4+KI, and delivered an energy output of 18.0 W h Kg -1 at 350 W Kg -1 , owing to the enlarged faradaic effect.
