Talk Title
Nitrogen-Doped 3D Hierarchically Porous Carbon Derived from Renewable Biomass for Energy Storage Application

Talk Abstract
 

The 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 m2 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 H2SO4 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-1 in 1 M H2SO4. 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.
