Is polymer lithium battery bulging dangerous?

I think everyone may have seen or heard of battery bulging and swelling, and even news incidents of explosion casualties caused by polymer lithium battery bulging. So why does polymer lithium battery bulge? It turned out that the internal diaphragm was damaged, and gas appeared inside the battery. The bulging of the battery will affect the use, and 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. The lithium battery has strict requirements on the charger and cannot be connected to the power supply at will. For sloppy charging, you must use a special charger for lithium batteries (such as balanced charging and safe charging). If the charger used does not meet the requirements, the battery may be swollen at the slightest level, and a safety accident or even an explosion may occur. may. Batteries must not be used anymore. Recycling is currently not realistic in our country. It can only be scrapped. So remind everyone that the drum kit is already a precursor to a big problem, and it is not recommended to use it anymore. It may be short-circuit, heat, smoke, burning and other unimaginable consequences if it continues to be used. The current lithium batteries are ion batteries (the interior is no longer in the form of lithium metal, it seems that the lithium metal and the moisture in the air burn or even explode, so it is relatively safer), all lithium batteries, whether they are previous or These years, including: polymer lithium batteries, lithium iron phosphate batteries, etc., are very afraid of internal short-circuit of the battery, external short-circuit of the battery, and overcharge. The bulge is caused by the accumulation of irreversible dendrites on the plate. The correct usage is that in most cases, only half of the power is used up and then the power is supplemented. In rare cases, a complete discharge and full charge maintenance (such as It takes a few months to half a year to completely discharge and charge once. Frequent full charge and discharge are easy to grow crystals. This can greatly reduce the amount of crystals and significantly slow down the phenomenon of bulging. The bulging lithium battery can be directly discarded, because the power capacity is already very small, and there is no power to speak of after a short circuit. Lithium batteries generally need to be professionally recycled to prevent pollution. If they cannot be disposed of, they can be thrown into the sorted recycling trash bin at the service point of the telecommunications service provider.
