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.
Bearing in mind that the nominal voltage of the lead–acid batteries was 12 V, the currents of the pulses associated with 25, 50, and 100 Ω were 0.12, 0.24, and 0.48 A, respectively. In order to perform the measurement of the electrochemical impedance spectra, the batteries were fully charged.
Lead-acid batteries are widely used in all walks of life because of their excellent characteristics, but they are also facing problems such as the difficulty of estimating electricity and the difficulty of balancing batteries. Their large-scale application is partly due to the powerful battery management system.
The monitoring and diagnostic capabilities enable the implementation of improved battery management algorithms in order to increase the life expectancy of lead–acid batteries and report battery heath conditions. A basic calibration process with the Gamry laboratory instrument allowed the impedance value at 1 kHz to be adjusted with good precision.
Thus, lithium-ion research provides the lead-acid battery industry the tools it needs to more discretely analyse constant-current discharge curves in situ, namely ICA (δQ/δV vs. V) and DV (δQ/δV vs. Ah), which illuminate the mechanistic aspects of phase changes occurring in the PAM without the need of ex situ physiochemical techniques. 2.
Capacity degradation is the main failure mode of lead–acid batteries. Therefore, it is equivalent to predict the battery life and the change in battery residual capacity in the cycle. The definition of SOH is shown in Equation (1): where Ct is the actual capacity, C0 is nominal capacity.
