Porous carbons gain widespread acceptance in electrical double layer capacitors (so called super- or ultracapactors) as electrode materials owing to their high specific surface area providing conditions for attaining a high specific capacitance. To increase a power density of a supercapacitor it is necessary to reduce electrical resistance of electrodes. One way to obtain this result is a replacement of some atoms in carbon material network by heteroatoms. The increase in conductivity due to heteroatoms is stipulated by a presence of lone electron pairs or unoccupied orbitals which give a contribution in electron or hole conductance.
