“…High energy parameters, great cycle life, and low price of the HES capacitor of PbO 2 ͉H 2 SO 4 ͉C systems have drawn the attention of other experts who have been also actively involved in the re- search work of its electrode processes and design features in recent years 7,[11][12][13][14][15] with a view of further improving the energy and operation parameters. Lead dioxide is an active material of the positive nonpolarizable electrode of HES capacitor of PbO 2 ͉H 2 SO 4 ͉C system, while the negative electrode with DEL is made on the basis of activated carbon materials or conducting organic polymers.…”

A mathematical model of heterogeneous electrochemical supercapacitors ͑HES͒ is proposed which makes it possible to develop capacitors with optimal designs and make calculations of their energy, capacity, and power parameters. Special attention is paid to the processes which occur in electrodes with double electric layer ͑DEL͒ of HES capacitors during their charge and discharge by different currents. It is demonstrated theoretically that in the efficiency of HES capacitors' operation, an important role is played by distribution of the potential along the thickness of electrodes with DEL. In order to build capacitors with improved parameters and optimal design, it is of paramount importance to take account of the type and value of conductivity of the material of the electrode with DEL and conductivity of the electrolyte in its pores. Analysis is performed to determine the efficiency of PbO 2 ͉H 2 SO 4 ͉C system capacitors' operation subject to thickness, conductivity, and specific capacitance of the electrode with DEL. It is established that energy and capacity parameters of the capacitors depend to a great extent on conductivity of their negative electrodes and electrolytes. It is demonstrated that there are different mechanisms of losses of energy and charge of the capacitors during their charge, discharge, and storage.
