Lead-Acid Test Cells and Measurement Equipment The lead-acid test cells consisted of one negative plate enclosed by two positive plates with separator bags. The plates and the separator bags were taken out of a commercial lead-acid starter-battery, wherein they were formatted by the manufacturer.
For the testing of lead-acid batteries, it is commen to use electro-chemical impedance spectroscopy ( EIS) [ 6, 7, 8, 9 ]. However, for SoH estimation EIS was intensively applied on other battery technologies such as lithium-ion batteries [ 10, 11, 12 ], but not yet on lead-acid batteries.
Understanding the thermodynamic and kinetic aspects of lead-acid battery structural and electrochemical changes during cycling through in-situ techniques is of the utmost importance for increasing the performance and life of these batteries in real-world applications.
In the evaluation of parameterized EEC of lead-acid batteries, most attention is given to the double-layer capacitance and the charge-transfer resistance, as both correspond to the electro-chemical charge and discharge process on the surface of the electrode [ 1, 2, 3, 4, 5 ].
In the charging and discharging process, the current is transmitted to the active substance through the skeleton, ensuring the cycle life of the lead acid battery. 3.4.2.
