How do you deal with the bump of polymer lithium battery?

Everyone may have seen or heard the expansion of the battery drum, and even news events due to explosions caused by polymer lithium battery drums exist. So why does a polymer lithium battery have a bulge? It was originally caused by damage to the internal diaphragm, and gas was generated inside the battery. After the battery drum pack, it will affect the use, and it will not be put into the mobile phone or digital camera. In addition, the presence of gas between the battery plates will also affect the charge and discharge capacity of the battery. The lithium battery has strict requirements on the charger, and cannot be connected to the power supply at will. To charge the sloppy, you must use a special charger for the lithium battery (such as balance charge and safe charge). If the charger used does not meet the requirements, the battery will be drummed, and the safety accident will occur, even the explosion. The battery must not be used anymore. Recycling is not realistic in China at present. It can only be scrapped.

So remind everyone that the drum kit is already a precursor to big problems, and it is not recommended to use it again. Reuse can be a short-term, heat, smoke, burning and other unimaginable consequences. The current lithium batteries are all ion batteries (the inside is no longer in the form of lithium metal, it seems to be burned or even bombed by lithium metal and moisture in the air, so it is relatively safe), all lithium-ion batteries, whether it is before, Still these years, including: polymer lithium-ion batteries , lithium iron phosphate batteries, etc., are very afraid of battery internal short circuit, battery external short circuit, overcharge. The drum kit is caused by the irreversible accumulation of dendritic crystals. The correct usage is that in most cases, only half of the upper and lower electricity is used to start replenishing the electricity. In rare cases, a complete discharge and full charge maintenance are performed (such as It takes a few months to half a year to completely recharge it, and it is easy to grow and crystallize when it is fully charged and recharged. This can greatly reduce the amount of crystallization and can significantly slow down the bulging phenomenon. The lithium battery of the drum kit can be directly discarded, because the power capacity is already very small, and there is no power after the short circuit. Lithium batteries generally need to be professionally recycled to avoid pollution. If there is no way to deal with them, throw them into the classified recycling bins of the telecommunications service providers.
