By current study determined dependence between changing of the average capacitance of the destroyed electrodes of chemical current sources, surface geometry and chemical composition of electrodes surface. In case of the minimum destruction of the surface of the electrode, the maximum value of the average capacity is achieved with the ratio Zn: Mn = 2: 1. The minimum capacity was been at a maximum concentration of manganese on the surface (Zn: Mn = 1: 3) and the maximum degree of destruction. That is, the destruction of the surface of the electrodes leads to a change in the ratio of Zinc and Manganese and with strong surface destruction, the number of Manganese increases significantly. The using of the second frequency-dependent parameter (capacitance dispersion) as a lumped parameter was allowed the application of the principles of electric current commutation for register the layered change in the electric characteristics of the destroyed electrodes. Due to that mathematical technique was obtained a visual picture of the quantitative and qualitative changes on the destroyed surfaces. The general view of the received diagrams repeated the contours of the SEM microphoto images of the same surfaces. There is a presence of sites with the local concentrated deviations from the total distribution of the capacitance in the specific frequency range in case of deep damage in the diagrams. Thus, these diagrams (EIS images) give a clear picture of the electrodes surface of and can be used to evaluate the type of surface damage and the degree of destruction of the electrodes of chemical current sources.
