Why is the lithium-ion battery exploded? How to prevent lithium-ion battery from explosion? At present, more and more battery cars are equipped with a lithium-ion battery, because of its light, and the long-lived welcome. Although the lithium-ion battery is generally very safe, they will occasionally catch fire or exploded. The power of the lithium-ion battery is huge, if not used properly, the consequence is quite dangerous.

So, in what circumstances, the lithium-ion battery will have a safety hidden danger? Is there any way to prevent a lithium-ion battery? Let us come to find out. Reasons for the explosion of lithium-ion battery (1) Internal short circuit due to short-circuit phenomena internally, a large amount of thermal current discharge, a large amount of heat, burn a bad diaphragm, resulting in a larger short circuit, so that the battery will appear high temperature, so that the electrolysis The liquid decomposes the gas, causing the internal pressure to be too large, when the outer casing of the battery cannot withstand this pressure, the battery will explode. (2) External short-circuit external short circuit may cause improper operation, or misuse, due to external short circuit, battery discharge current is large, the heat of the battery can cause the diaphragm to shrink or completely damage the interior of the battery, resulting Internal short circuit, thus exploding.

(3) Charger in charge of charger or poor insulation is also damaged by lithium-ion batteries. If the charger shorts or heats near the battery, it can cause sufficient damage to failure. That is why we recommend using official charger.

(4) Temperature excessive temperature is high, refers to the heat of the battery reaches the limit, charging, high temperature irradiation, and baking are easy to cause too high. In the south of my country, the general family will use electric oven, many people like to roast the phone on the side of the electric oven, which is very dangerous. How to prevent lithium-ion battery explosion 1.

Use the original charger: charging time is the high incidence of lithium-ion battery explosion. Original charger is more powerful than compatible charger to ensure battery safety. 2.

Using Reliable Battery: Try to purchase the original battery or market-name brand battery, do not purchase "second-hand goods" or "water", such battery may be repaired, it is better to be reliable as the original battery or large factory brand battery. 3. Suitable: The low temperature protection mechanism of lithium-ion batteries can cause chemical reactions in the battery, so that it cannot be charged or the charging speed is slowed; the temperature is too high, the lithium ion battery is unstable, the performance of the charging battery material Will degrade, the battery life will also be greatly shortened, even caused explosion! Try to charge the phone charge in a relatively suitable temperature, stay away from high temperature.

4. Don't try to modify: The mobile phones sold in the formal market are qualified before leaving the factory. Quality is reliable.

If the phone is modified, the quality will not be guaranteed, and the probability of the battery explosion will become large. Although lithium-ion batteries sometimes fail, it is still a safe and mature technology. Because of this, it will become a news when the battery suddenly exploded, and this also shows how rare failure is.

Battery manufacturers prevent battery failure, install a large amount of protective measures, or at least reduce the damage caused by the fault. Therefore, for your safety, please purchase and use lithium-ion batteries correctly, and let the lithium-ion battery becomes a dangerous goods around you!.
