Azide-assisted hydrothermal synthesis of N-doped active carbon with high conductivity for supercapacitor
In our investigation, the sodium azide–assisted hydrothermal method was employed to prepare the N-doped active carbon (NAC). The TEM image shows that the NAC demonstrated lattice fringes (0.398 nm) representing the graphitized area. The NAC has high adsorption surface (1903 m 2 g −1 ). A variety of...

| description | In our investigation, the sodium azide–assisted hydrothermal method was employed to prepare the N-doped active carbon (NAC). The TEM image shows that the NAC demonstrated lattice fringes (0.398 nm) representing the graphitized area. The NAC has high adsorption surface (1903 m

g
−1
). A variety of faradaic-active species (pyrrolic-N, pyridine-N, quaternary-N) provide many electrochemically active sites. The
R
ct
of the NAC decreased by approximately 31.25% and the capacitances of the NAC increased by approximately 45.7% compared with the AC in a three-electrode configuration in 1 M Na

solution. Besides, it could retain 96.1% after 5000 cycles at 1 A g

. The NAC device could achieve the high capacitance of 40 F g

in 1 M LiPF

/PC and high energy density of 50 Wh kg

at 0.762 kW kg
