Description

Explosion-proof lead-acid battery Technical Field The utility model relates to the technical field of lead-acid storage batteries, in particular to an explosion-proof lead-acid storage battery. Background When the lead-acid storage battery is charged to reach the peak, the charging current is only used for decomposing water in the electrolyte, at the moment, the positive electrode of the battery generates oxygen, the negative electrode generates hydrogen, and the gas overflows from the storage battery, so that the electrolyte is reduced, and water is needed to be added at random. On the other hand, in the final charging or overcharging condition, the charging energy is used to decompose water, and oxygen generated in the positive electrode reacts with sponge lead in the negative electrode, so that a part of the negative electrode is in an underfilled state, and the generation of hydrogen in the negative electrode is suppressed. The lead-acid storage battery can generate inflammable and explosive gases such as hydrogen, oxygen and the like and acid mist in the charging and discharging process. The traditional lead-acid storage battery exhaust mode is mainly characterized in that each battery monomer is independently exhausted, gas exhaust paths are dispersed, and the risk of explosion of gas when encountering open fire is increased. Meanwhile, the dispersed exhaust is difficult to effectively treat the acid mist, and the acid mist can not only corrode peripheral equipment, but also possibly cause harm to the environment and human body.
