“…It will be valuable to correlate lab test results to real-life experiences as soon as reliable data are available. The first results published by BMW look quite promising for the application of AGM batteries in micro-hybrid vehicles [1,18].…”

“…This ensures that the test is easily set up in different labs and the results are comparable and reproducible. A high-rate discharge is not part of the original DPC test pattern, but may be implemented [6]. The pre-treatment schedules a series of C/20 tests prior to the first cycling unit to estimate a capacity baseline unaffected by the subsequent cycling test.…”

“…The PAM subsequently sheds from the positive electrode grid, although, in appearance, the electrode seems to be in a good condition [17]. The PAM softening and shedding are a result of the increasingly small PAM particles and their weak coherence with each other during cycles [14,[18][19][20], as Figure 1 shows.…”

Summary The lead–acid battery (LAB) has been one of the main secondary electrochemical power sources with wide application in various fields (transport vehicles, telecommunications, information technologies, etc.). It has won a dominating position in energy storage and load‐leveling applications. However, the failure of LAB becomes the key barrier for its further development and application. Therefore, understanding the failure modes and mechanism of LAB is of great significance. The failure modes of LAB mainly include two aspects: failure of the positive electrode and negative electrode. The degradations of active material and grid corrosion are the two major failure modes for positive electrode, while the irreversible sulfation is the most common failure mode for the negative electrode. Introduction of carbon materials to the negative electrodes of LAB could suppress sulfation problem and enhance the battery performance efficiently. This paper will attempt here to pull together observations made by previous research to obtain a more comprehensive and integrative view of LAB failure modes. Moreover, according to a detail investigation to the battery market, we have drawn an objective and optimistic conclusion of LAB prospect. Copyright © 2016 John Wiley & Sons, Ltd.

“…With this feature, the dynamic charge acceptance (DCA) is presented as a key parameter for the lead acid battery [3,4]. To meet this requirement, the battery would operate at a partial state of charge (PSoC) [2,[5][6][7][8][9][10]. Under these several requirements presented in the microhybrid vehicles, the lead acid battery lifetime is significantly reduced.…”

“…Therefore, the electrolyte stratification must be reduced for obtaining a performant battery type for the PSoC applications. The comparison between the AGM, EFB and standard flooded battery is also investigated by Schaeck et al [7]. A micro-cycling test (MCT) was developed.…”

Lead acid battery with mixing element is a new battery technology adopted for micro-hybrid vehicles. This battery technology is based on the use of the mixing element. The aim of this paper was to study the hydrostatic pump created using the mixing element. A numerical simulation is performed to predict the pumping phenomenon occurred under the liquid sloshing in the battery cell subjected to sinusoidal excitation. The volume of fluid method based on the finite volume method is used to simulate two-phase flow in the battery cell partially filled with liquid. The distribution of the static pressure and the velocity in whole volume of the cell are presented and analyzed to understand the operating mode of the hydrostatic pump. An experimental setup with sinusoidal movement is developed, and the hydrostatic pump in the battery cell partially filled with liquid is studied. The comparison between the numerical and the experimental results shows a good agreement. In addition, an initially stratified lead acid battery cell is prepared. The effect of sinusoidal acceleration on the stratified cell is investigated. The experimental results show that hydrostatic pump can eliminate the liquid stratification under the acceleration effect.
