Briefly analyze various factors that affect the life of lead-acid batteries

Recycling lead batteries is a demand issue, and method is the key. Third-party power can be used to establish standardized collection channels. If companies cannot arrange standard channels, they must concentrate their existing collection teams. Some companies have established their own waste battery recycling networks, but they need guidance from standard demonstration companies. In this regard, Liu Yanlong called on major lead battery companies to rationally use sales channels, such as replacing old ones. Collect and sell lead batteries. However, if the battery is still a dangerous product, each sales point should be prepared to meet the recycling conditions and engage in the collection work.

To collect more information separately, it is up to economic interests to determine who will dispose of the collected used batteries. Some companies that re-use may be illegal, and some are unqualified but are still being processed. In this way, the waste batteries collected by the company can be incinerated, reducing costs; it can also smash the battery heads and pour out the waste acid and lead mud inside, which will also cause pollution; in addition, hand over plastics such as plates to illegal factories Disposal will cause secondary pollution. Therefore, this may be another major cause of lead-acid battery contamination. Therefore, standardize the collected specifications.

Factors affecting the life of the bottle;

Over-filled ethylene separators will produce a large amount of gas precipitation. During the impact, the active material of the positive electrode plate will fall off after being impacted by the gas, and the positive electrode grid alloy will also undergo severe anodic oxidation and corrosion, thereby shortening the battery overcharge life.

Since the positive electrode of lead dioxide produces lead sulfate when it is discharged, the volume of the active material is larger than that of lead oxide. One mole of lead oxide generates one mole of lead sulfate, which increases the volume by 95%. Such repeated contraction and expansion will gradually loosen the bond between the lead dioxide particles and easily fall off. The shrinkage and expansion are significantly reduced, the bonding force is destroyed slowly, and the deeper the discharge depth, the shorter the cycle life.

The service life of lead-acid batteries increases with increasing temperature. For every increase of 35℃~45℃, every 1℃ increase, every 5-6 times increase, and every 1℃ increase, the service life can be extended 25 times; above 50℃, the vulcanization capacity of the separator negative electrode will be lost , So that life expectancy is reduced.
