T
he development of renewable carbon sources for sustainable supercapacitor is of significance importance. Herein, the
synthesis of three-dimensional N-doped carbons derived from lecithin via a simple route was reported. Hierarchical
porous carbons with high surface area (up to 1803 m

g
−1
) along with nitrogen-doping level (up to 9.2 wt. %) were successfully
prepared by hydrothermal carbonization and a subsequent thermal annealing. The electrochemical performance of the carbon
electrodes was examined with both two and three-electrode cell configurations in 1 M KOH and 1 M H

electrolytes. The
as-prepared electrode features a large specific capacitance (285 F g
-1
at 0.5 A g-1), high-rate capacitive behavior, and long-term
cycling stability (8% loss after 20000 cycles). Furthermore, obtained electrode exhibits an energy density of 24.7 W h kg-1 at
a power density of 500 W kg

in 1 M H

. The excellent electrochemical performance of N-doped carbons is attributed
to the unique hierarchical porous frameworks along with pseudocapacitive effect. This work opens up a new approach for
preparation of hierarchical N-doped porous carbon materials with tailored properties for supercapacitor applications.
