Is it dangerous to lithium polymer battery bulge?

Source: 2020 - 04 - 12 21:05 hits: lithium polymer battery inflation risk? Expansion of the lithium battery I think you may have seen or heard of the expansion of the battery drum, some even die of caused by the explosion of the polymer lithium battery drum. Then why polymer lithium battery can expand? Turned out to be the internal diaphragm damage, make a battery produced gas. Cell expansion effect after use, put not into the mobile phone or digital camera, the existence of other gases between the battery plate will also affect battery charge and discharge capacity of lithium battery charger has strict requirements, not casually, careless charging power supply, be sure to use special lithium battery charger, ( Such as balance charger charger and security) If you use the charger is not in conformity with the light, make the expansion of the battery requirements, safety accident in heavy, even explosion is possible. The battery shall not be used again. The recycling in China is not realistic. It can only be abandoned. So remind everybody, the bulge is a precursor to a problem, suggest don't use. Use may occur after short circuit, fever, such as smoking, burning unimaginable consequences. The battery is lithium ion battery ( Internal no longer exists in the form of metallic lithium, seems to be due to the lithium and even burning explosion and moisture in the air, so relatively safe) , all of the lithium ion battery, whether before or over the years, including: polymer lithium ion battery, lithium iron phosphate batteries and so on, are very afraid of internal short circuit and external short circuit batteries, battery overcharge. Bump, irreversible dendrite accumulation caused by the board, the correct usage is, in most cases is only half the power fluctuation of electricity, in rare cases, a complete discharge and fully charged maintenance ( Such as using a few months to half a year will be fully charged, fully charged often easy crystallization) , it can greatly reduce the crystallization, can significantly reduce inflation. Ballooning lithium battery can be discarded, because power capacity is very small, no power after short circuit. Lithium battery generally professional recycling will not cause pollution, if there is no way to deal with it, it is thrown into the classification of the telecommunication service provider service point recycling bins.
