Can lithium polymer batteries explode? How to prevent lithium battery explosion? Polymer lithium battery is a kind of lithium battery product made of soft packaging and polymer electrolyte. Under normal conditions, it will not explode in use and storage, unless it is short circuit caused by artificial strong damage. Lithium batteries are flammable devices, and devices with lithium batteries inside such as mobile phones and scooters will explode if not used properly. This article gives you a small series of methods to prevent lithium battery explosion.
Can lithium polymer batteries explode?
The current lithium polymer battery is soft pack battery, using aluminum plastic film as the shell, when the internal use of organic electrolyte, even if the liquid is very hot does not explode, because aluminum plastic film polymer battery using solid or colloidal state without leakage, but natural rupture. But nothing is guaranteed, and if the instantaneous current is high enough for a short circuit to occur, it is not impossible that the battery will spontaneously ignite or burst, which is often the cause of safety accidents in phones and tablets.
In low temperature environment, the low temperature protection mechanism of polymer lithium battery will prevent chemical reactions of substances in the battery, so the battery cannot be charged or the charging speed is slowed down, while at high temperature, the battery will be unstable and even cause explosion.
Lithium polymer battery, also known as polymer battery. Compared with lithium-ion batteries, the biggest difference in safety lies in the fact that when two batteries are heated to a certain extent, lithium-ion batteries will explode, while lithium polymer batteries will only volatilize chemical properties, and at most burn and never explode.
In terms of structure, polymer batteries generally use flexible packaging, the shell is thin and soft, lithium ion batteries mostly use hard packaging, the shell is thick and hard, from the perspective of safety, once the battery of flexible packaging sudden damage, such as charging voltage is too high, high temperature caused by the explosion, its damage is far less than that of hard packaging lithium batteries.
How to prevent lithium battery explosion?
We can put the emphasis on the prevention of lithium battery overcharge, the prevention of external short circuit, and improve the safety of the cell three-way explosion-proof focus on the above.
1. Use the original charger: Charging time is a high occurrence period of lithium battery explosion events. Original chargers are better at keeping batteries safe than compatible chargers.
2. Use reliable batteries: try to buy original batteries or well-known brand batteries in the market, such as lithium batteries, do not buy second-hand or parallel goods to save money, this kind of battery may be repaired, as reliable as the original battery.
3. Avoid placing lithium battery in high temperature environment.
4. The design of lithium battery protection circuit board, although it will increase the manufacturing cost of lithium battery, but for the safe use of lithium battery is necessary, all regular new lithium battery manufacturers of products are unavoidable this design.
As long as the above points, in line with the safety standards of lithium batteries will not become a time bomb in our hands.
