Lithium battery plate product equipment

individual collection is more about who will dispose of the used batteries collected by the decision on economic benefits. Some recycled companies may be illegal, and some of the recycled ones are unqualified, but are still being disposed of. This kind of company collects used batteries for incineration and disposal in the future to reduce costs; it can also smash the battery heads and throw out the waste acid and lead mud inside it, which will also constitute pollution; otherwise, it will use useful plastic For example, the plates are given to some illegal factories for disposal. The environmental protection measures of these factories are not guaranteed. This will cause secondary pollution. Therefore, this can be another primary source of lead-acid battery pollution. Therefore, it is necessary to introduce some enforceable rules to standardize collection methods. Factors affecting the life of lead-acid batteries: The degree of overcharging of the PE separator, a large amount of gas precipitates during overcharging. At this time, the positive electrode active material is subject to the impact of the gas, and this impact will promote the fall of the active material. In addition, the positive electrode grid alloy also Suffering from severe anodic oxidation and corrosion, so the battery will shorten the application period when the battery is overcharged. The depth of discharge, because the positive electrode active material lead dioxide itself is not well integrated with each other, lead sulfate is generated during discharge, and it returns to lead dioxide during charging. If the molar volume of lead sulfate is larger than that of lead oxide, the volume of the active material will expand during discharge. If one mole of lead oxide is converted into one mole of lead sulfate, the volume will increase by 95%. In this way, repeated contraction and expansion will cause the lead dioxide particles to The mutual bonding of the particles gradually relaxes and is easy to fall off. If only 20% of one mole of the active mate
