Why do polymer lithium-ion batteries have bulges?
Overall, the problem of bulging in polymer lithium-ion batteries is mainly due to two reasons. One is that polymer lithium-ion batteries cause overcharging or overdischarging during use. The second reason is that the manufacturing level of the battery is not very good, and the material used is too poor. The main reason is that the production technology and process are relatively fair and rough. So, let me explain in detail: Why do polymer lithium-ion batteries have bulges?
Why do lithium batteries have bulges
1. During the operation of lithium batteries, there are issues of overcharging and overdischarging. During use, there is a strong reaction inside the battery that is infinitely close to a short circuit, generating a large amount of heat, which leads to electrolyte decomposition and gasification, causing the battery to bulge.
2. The strong reaction of short circuit generates a large amount of heat, which leads to electrolyte decomposition and gasification, causing the battery to bulge;
3. In addition, lithium battery packs can also experience bulging if not used for a long time, because air is conductive to a certain extent. Therefore, prolonged use is equivalent to direct contact between the positive and negative electrodes of the battery, leading to a chronic short circuit;
What should I do if my lithium battery bulges?
Bulging is already a precursor to a major problem, and it is not recommended to use it again. Batteries must not be used again. Recycling is currently not feasible in China and can only be disposed of as scrap. We need to stop using it immediately. For our own safety, if the lithium battery pack has bulged or expanded, please do not continue to use it to avoid dangerous situations. At this time, please replace the lithium battery in a timely manner.
Repair methods for lithium battery bulges in mobile phones:
1.If the phone battery has already been charged and swollen, there is a good way to solve it. It is to use your fingers to first find the gap in the battery (the back of the phone battery is close to the charging electrode of the phone, where it is a bit soft when pressed down), and then poke a small hole to let the air inside come out.
2. In addition, when buying a battery, I believe everyone knows that the battery is the source of power for the phone, which is actually the power of the phone. Without the power supply of
lithium batteries, the phone is just a metal sheet, a high-capacity and high-performance battery that can charge the phone for a longer period of time.
