Chemical capacitance, definition

The special role of and is worth mentioning in this context in that they are derived directly from the resistive parameter. The concentration term involved (included by definition) is not effective as chemical capacitance, since 5p=0 and the transient behaviour is merely determined by dielectric effects (i.e. by electrical capacitances). This alters, if chemical changes must also be taken into account in the electrical experiments. Then the conceptual boundaries between the electriceil and the chemical experiment disappear (see Section 7.3.4). 

Surely, the nitrogen presence has a profitable effect on the capacitance values, as well as for good capacitor performance at drastic current loads. However, an excess of nitrogen (presumably over 15%] will definitively aggravate the conducting properties, and in turn, the capacitance characteristics and supercapacitor cyclability. The form in which N participates in the carbon network is especially important. It seems that the effect of -NH2 groups outside of the matrix, with N chemically bound to the carbon network ("chemical nitrogen"), will be of less importance and most probably...
