I think everyone may have seen or heard of lithium battery packs bulging and swelling, and there are even news incidents of explosion casualties caused by the bulging of polymer lithium batteries. So why does polymer lithium battery bulge? It turned out that the internal diaphragm was damaged, and gas was generated inside the battery.

    When the mobile power polymer battery is swollen, it will affect the use. It cannot be put into the mobile phone or digital camera. In addition, the presence of gas between the battery plates will also affect the charging and discharging capacity of the battery. Lithium batteries have strict requirements on the charger and cannot be arbitrarily If you can connect to the power supply, you can charge it carelessly. You must use a special charger for lithium batteries. If you use a charger that does not meet the requirements, the battery may be swollen, or a safety accident or explosion may occur.

    So remind everyone that the bulge of the lithium battery is already a precursor to a major problem, and it is not recommended to use it. It may be short-circuit, heat, smoke, burning and other unimaginable consequences if it continues to be used. The correct usage of lithium batteries is that in most cases, only half of the power is used up and then start to replenish the power. In rare cases, a complete discharge and full charge maintenance are performed. This can greatly reduce the amount of crystallization and significantly slow down the polymer lithium. Batteries are bulging.

    As long as it is a lithium battery, there is a risk of explosion, but this is a small risk. But once it explodes, the greater the capacity of the lithium battery, the more powerful it will explode. Lithium polymer battery will generate gas inside it after using it for a long time, so it will swell. In order to prevent lithium-ion batteries from overheating or even exploding, modern lithium-ion batteries have built-in many self-protection mechanisms. For the safety of users, it is not recommended to continue using the bulging lithium battery!
