Resistivity and Impedance Changes of Lead-Acid Accumulator

Abstract: This paper describes active mass and collector resistivity and impedance changes of lead-acid accumulator electrodes. Data was obtained during experiment with pulse charging cycling of old lead-acid accumulator. Resistivity changes of active mass and collector were measured using four-point direct current method. Impedance changes were observed by electrochemical impedance spectroscopy. Old lead-acid accumulator previously not used for almost half of a year was used in the experiment. Reasons why pulse chargi… Show more

“…It seems that via electrochemical impedance spectroscopy (EIS), it is more likely that faulty batteries will be detected. The combination of the two above-mentioned techniques should allow for the prediction and/or the identification of battery parts with significant capacity losses, without discharging the battery; the method also shows high reliability [3][4][5][6][7][8].…”
