This paper reviews the relationship between battery fire and failure modes. Four failure modes influenced on the valve regulated lead acid battery were emphatically analyzed: “Sulfation of negative electrode plate”, “corrosion of the positive electrode plate”, “loss of water” and “acid leak”.
Failure modes of the valve regulated lead acid battery will not only greatly reduce the service life, but also may start a fire. This paper reviews the relationship between battery fire and failure modes.
Besides the battery short circuit and thermal runaway, another significant reason for battery fire is the explosion caused by hydrogen evolution. Therefore, it is of great importance to analyze the properties of the gas component generated during both charging and discharging process.
Provided by the Springer Nature SharedIt content-sharing initiative The liberation of hydrogen gas and corrosion of negative plate (Pb) inside lead-acid batteries are the most serious threats on the battery performance.
Nevertheless, positive grid corrosion is probably still the most frequent, general cause of lead–acid battery failure, especially in prominent applications, such as for instance in automotive (SLI) batteries and in stand-by batteries. Pictures, as shown in Fig. 1 taken during post-mortem inspection, are familiar to every battery technician.
The development of lead carbon battery solves the sulfation of negative electrode under HRPSoC, inhibits the occurrence of side reactions such as hydrogen evolution, and enhances the charge/discharge efficiency and cycle life. At present, we are leading the extension of the real LAB in the form of a lead carbon energy storage device.

For example, the grid in lead–acid batteries is made of solid lead and the active mass, a sponged lead for the negative electrode is pressed into the grid. The grid itself is maybe only partially exposed to electrolyte and it mainly serves as the mechanical support for the active mass and as a current collector.
