Description

Technical Field

[0001] This utility model relates to the field of lead-acid battery technology, and in particular to an explosion-proof lead-acid battery. Background Technology

[0002] When a lead-acid battery is nearing the end of its charge, the charging current is used only to decompose the water in the electrolyte. At this time, oxygen is produced at the positive electrode and hydrogen is produced at the negative electrode. This gas will escape from the battery, causing a reduction in electrolyte level, requiring the addition of water periodically. On the other hand, towards the end of the charge or under overcharge conditions, the charging energy is used to decompose the water. The oxygen produced at the positive electrode reacts with the spongy lead at the negative electrode, leaving part of the negative electrode in an incompletely charged state and inhibiting the production of hydrogen at the negative electrode.

[0003] Lead-acid batteries produce flammable and explosive gases such as hydrogen and oxygen, as well as acid mist, during charging and discharging. Traditional lead-acid battery venting methods typically involve independent venting from each individual battery cell, resulting in dispersed gas emission paths and increasing the risk of explosion if the gases come into contact with an open flame. Furthermore, dispersed venting makes it difficult to effectively control acid mist, which can corrode surrounding equipment and potentially harm the environment and human health.

The exhaust port is equipped with a gas-liquid filter cotton adsorption layer, which can adsorb acidic substances and impurities in the exhaust gas to ensure exhaust safety. The battery exhaust is connected through an exhaust assembly. The sealing rubber head of the exhaust assembly can ensure a tight connection and good sealing.
