Can the lithium-ion battery pack be used if it is swollen?

Can lithium batteries still be used? The reason for the bulging of lithium batteries, can lithium battery packs be used? In recent years, lithium batteries have been widely used in the market due to their high energy ratio and high safety. Although the safety of lithium batteries is much higher than that of lead-acid batteries, it can be assumed that improper use or low processing levels still have certain safety risks, such as expansion problems. What is the cause of the bulge of the lithium battery? There are two important reasons for the bulge of the lithium battery. One is the manufacturer's problems, the harsh processing environment, and the outdated processing equipment, which makes the battery coating uneven and the electrolyte is mixed with dust particles. All of these may make the lithium battery pack bulge in the user's use, or even more dangerous. There is also a reason for the user. It is assumed that the user uses the lithium battery product improperly, such as overcharge and overdischarge, or continuous use in an extremely harsh environment, which may also cause the lithium battery to swell. In addition to these two important reasons, there is one more rare reason. In other words, the battery is not used for a long time, and then there is no interruption for better storage handling. When it is exposed to the air for a long time, it is not used and fully charged. Because air is conductive, at a certain level, too much time is equivalent to direct contact between the positive and negative electrodes of the battery, interrupted by a slow short circuit. The important principle of lithium battery attack is that the internal attack of the battery is a strong response similar to a short circuit, a large amount of heat appears, and then the composition of the electrolyte is vaporized, and the lithium battery will flourish. Can the lithium battery assembly bag continue to be used? When the lithium battery pack has a problem, it is best not to continue using the battery. Because the cell attack is shortened, when it is shortened to a certain limit, it may cause an explosion, which is very dangerous. For your own safety, it is best to replace the lithium battery pack as soon as you find a bulge. What should I do with bulging lithium battery packs? For the safety of users, bulging lithium battery packs are not suitable for continued use. Because of the crystals inside, they cannot be used. Generally, professional lithium battery pack recycling treatment will not pollute the environment, so it is best to discard it to a professional lithium battery pack recycling station. Assuming that there is no garbage disposal center in the local area, the best way is to dump the garbage into the recycling bin. Under normal circumstances, the purchased lithium battery pack is consumed by the manufacturer on the right track. Pay attention to the method of use during use, which can prevent the bulging problem to the greatest extent.
