Essay

The thermodynamic and kinetic properties iodne- doping modification of activated carbon materials and polyaniline and efficiency of this process in pseudocapacitive devices energy storage was studied. An impedance analysis of activated carbon material doped with iodine was made, which gives a good trend of resistance decreasing during charge and strong increase of pseudocapacity. It was established that activated carbon material doped with bromine, in comprising with iodide doping modification increases the maximum of discharge potential of the electrode, which leads to a significant increase in the specific energy. It is shown that the use of iodine and bromine, as dopant, provides the increase of the density of delocalized impurity states, which increases specific capacitance in 2,4-2,6 times.
