Abstract
We report on the pseudo‐capacitance induced by a nitrogen substituted in the carbon network composite prepared by a simple carbonisation (750 °C) of formaldehyde and melamine in the presence of carbon nanotubes. Nitrogen content in the composites varied from 7.4 to 21.7 wt.%. Such materials have a higher density than activated carbons, hence, they can supply better volumetric capacity. N‐rich composites show an excellent charge propagation at current loads from 500 mA g–1 to 50 A g–1 because of multiwalled nanotubes which play a conducting as well as a supporting role. The electrochemical performance of various composites was investigated in two‐ and three‐electrode cells using acidic (1 mol L–1 H2SO4), alkaline (6 mol L–1KOH), neutral (1 mol L–1 Na2SO4) and organic electrolytes (1 mol L–1 TEABF4 in acetonitrile). Organic and neutral medium is not adapted for N‐rich carbon electrodes of supercapacitor. The detailed electrochemical characterisation pointed out the differences of charge propagation of electrodes with the different polarity.
