“…When LAB is operated continuously under partial state of charge (PSoC) and experiences charge and discharge process under HRPSoC cycling and deep cycle use, the negative electrode takes over from the positive as the lifelimiting element [74]. PbSO 4 will quickly accumulate on the surface of negative electrode [75], which cannot be converted efficiently back to Pb during charge [76].…”

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.

“…This degradation occurs as a result of repeated cycles, preventing PbO 2 from effectively engaging in the charge-discharge phase. 8 The negative electrode becomes the limiting factor in the lifespan due to the rise in temperature and high-rate partial state of charge, resulting in shedding and softening of the positive active material and the occurrence of irreversible sulfation, 9 the battery can function indefinitely while operating at varying levels of charge, including participating in charge-discharge cycles with high-rate partial charging and deep cycling. 8 Even though PbSO 4 deposits quickly on the negative electrode surface, it is not converted into Pb and PbO 2 entirely at the time of charging.…”

Thermal management of the battery is essential for effective utilization in various environmental conditions and for long-term usage. Failure of controlling and monitoring of battery over-heat leads to thermal runaway which causes battery explosion. This paper emphasizes the overheating phenomena of lead-acid batteries in stimulated heat situations. Heat is applied to the battery until the battery gets damaged. After the thermal damage to the battery, various characterization methods were performed to analyze the thermal influence on the anode and cathode plates. The characteristics methods are Differential Scanning Calorimetry (DSC) and Scanning Electron Microscope (SEM). DSC method is used to find the change in glass transition temperature of anode and cathode materials, which can provide the material thermal behavior over different temperatures. Likewise, SEM is used to investigate the structural morphology of anode and cathode plates. The experimental results are indicating the material degradation improves with different temperature range on both the anode and cathode plates. In particular, plate thermal influence varies at different positions which leads to the change of plate conduction. Additionally, thermography heat distribution images are used to identify the heat flow in the battery during the cycle period.
