Electrochemical performances of nitrogen-doped mesoporus carbons derived from tannin

The EDL mechanism leads to high power outputs but, usually, to low energy densities in comparison with batteries. Among the strategies to improve carbon-based supercapacitors performances, themodification of the surface chemistry is frequently used. The introduction of heteroatoms incarbon materials can enhance theirelectrical conductivity and/or their affinity towards the electrolyte, in addition to enabling redox reactions that provide a pseudocapacitance contribution, thus further increasing the capacitance.Jimena Castro-Gutiérrez gratefully acknowledges CONACYT-SENER for the assigned scholarship to support her Ph.D. studies, resulting in the work presented herein.
