Undoubtedly, when the lithium battery has obvious bulging phenomenon, please immediately stop the use of the lithium battery, the bulging lithium battery contains high pressure flammable gas, once the accident, the consequences will be very serious. This time also can not be lithium battery skin piercing to the lithium battery deflation operation, because this will not make the lithium battery any better, but will directly lead to the lithium battery scrap, and also accompanied by danger.
Perhaps you have more or less seen or heard the news of lithium battery explosion, or even the news of explosion casualties caused by the expansion of polymer lithium battery pack. Then why polymer lithium batteries will expand and bulge? It is proven to be due to damage of the internal diaphragm, and the gas is generated inside the battery.
After the bulge lithium polymer will affect the use to fit to cell phones or digital cameras, the presence of additional gas will affect the charge and discharge capacity of the battery between the plates, the presence of the charger used for lithium batteries strict requirements, can not be arbitrarily connected to power charging sloppy, must use lithium battery charger can only be used, if the charger does not meet the requirements of the battery pack from the drum, and then again an accident, and even an explosion may occur.
So we remind ourselves that everyone, lithium battery bulge is already a precursor to a big problem, it is not recommended to use again. Further use of students may exist is a short circuit, heat, smoke, burning and other unimaginable consequences. Li-ion battery can be the correct use is that most of this case only after half up and down the power to start developing supplementary power, very few cases before analysis once with a complete discharge and completely different charging technology maintenance, which can greatly reduce the amount of cultural crystallization, can significantly improve the slowing down of lithium polymer battery bulge phenomenon.
As long as the lithium battery, there is a risk of explosion, but this risk is very small probability. But once the explosion, the larger the lithium battery the greater the ability to explode with force. With a long gas lithium polymer battery produced internally, it expands. To prevent lithium-ion batteries from overheating or exploding, modern lithium-ion batteries have a lot of self-protection mechanisms built in. It is still not recommended for the safety of the user.
Once a lithium polymer battery bulge is found, be sure to stop using it. Lithium batteries up when charging overcharge, the internal chemical properties of the battery changes, resulting in gas, the general polymer soft pack battery overcharge will "bulge", if the steel-cased battery will explode. Be careful when using, it is best not to use cheap chargers, cheap chargers have a great impact on battery life. The "bulging" battery is best not to use, it is very dangerous, it is recommended to replace.
