How to Report a Lithium Battery Explosion

In daily life, lithium batteries can be found almost everywhere, ranging from electric cars to computer motherboard batteries. Lithium batteries have become an indispensable part of people. We often see various safety accidents caused by lithium batteries. The most impressive are the explosions and fires caused by lithium batteries. Come to see? 1. Avoid short circuit and overload. Almost most safety accidents caused by lithium batteries are caused by short circuit. We know that when the positive and negative electrodes of the battery are connected to each other in an abnormal path with very low resistance, what we often call a short circuit, very large current and heat will be generated at the inside the battery, which will cause in the event of excessive heat and electrical energy, the releaseNot only will it cause serious damage to the battery life, but also for sealed and packaged lithium batteries, a certain pressure will be generated inside the battery, causing the internal pressure to suddenly increase. of the battery, and because the chemical properties of lithium ions are very active, they will eventually cause an explosion and burn the shell. Due to the chemical characteristics of lithium-ion batteries, when we overcharge (overcharge) the battery, the negative electrode of the lithium battery cannot incorporate more lithium ions, causing the lithium ions to precipitate as lithium metal on the surface of the negative electrode, causing lithium dendrite phenomenon When the lithium dendrite grows to a certain extent, it pierces the separator, causing an internal short circuit in the battery, damaging the separator and short circuitsInternal incidents will also occur, leading to safety accidents. Therefore, when we use lithium batteries daily, we should try to avoid short circuit or overcharge. However, for most current digital products, their internal charging circuits will be equipped with corresponding protection ICs to prevent lithium batteries from being overcharged. detects that the lithium battery has reached a fully charged state, it will automatically cut off the charging circuit. However, it is still not recommended to connect cell phones or other devices to a powered charger for a long time. After all, no one wants to risk their cell phone or other devices, or even their personal safety, with a little charging protection. chip. 2. Puncture is also very dangerous. Compared to short circuit and overcharge, puncturing a battery atlithium is also a very unwise approach. If a lithium battery is pierced by a hard object, the lithium ions it contains will directly react chemically with oxygen in the air and violent combustion will also occur. For lithium batteries themselves or other electronic products containing lithium batteries, we usually see eye-catching trash signs. If lithium batteries are thrown away at will, it will not only cause environmental pollution, but also cause fires and other situations during the waste disposal process. 3. Avoid high temperatures and fires. High temperatures or fires will also cause lithium batteries to explode and burn. Especially in hot summer or in a car exposed to the sun for a long time, the ambient temperature of the lithium battery will be higher than its normal storage temperature. PaTherefore, when using equipment containing lithium-ion batteries, we should try to avoid using them in an environment with excessively high temperatures for a long time, although lithium batteries take a relatively long time to explode and burn if they are directly exposed to it. fire. There will always be a sudden increase in internal pressure, which we often call a bulge. When our cell phone battery or other lithium-ion battery bulges, we should immediately cut off the power supply and stop using it. use to prevent further increase in internal pressure, and replace the battery with a new one.
