Originální abstrakt

New AC difference method (ACDM) was developed to obtain experimental data. The original DC difference method (DCDM) was established earlier at our Power Sources Laboratory of Brno University of Technology [1, 2]. New method in its AC nature is also a close relative to electrochemical impedance spectroscopy (EIS). The DCDM and also the new ACDM are both non-destructive, which means that experimental data can be obtained in situ. New method provides more accurate set of information because it can be used in wide frequency range. Unlike the EIS the DCDM method gives us more information about current collector/active mass contact layer and active mass itself. In this paper, the new method was used to compare lead-acid accumulator in different states of charge. Electrodes were analysed with special attention to collector /active mass double layer and to active mass itself. Obtained data contributed to better understanding of involved degradation mechanisms.
