How to properly prevent battery explosion

The emergence of lithium batteries has greatly improved the power supply of various digital products. In our daily life, products that use lithium batteries can be seen almost everywhere, from electric cars to computer motherboard batteries. Lithium batteries have become an indispensable part of people. However, in recent years, we have often seen various safety accidents caused by lithium batteries. The most impressive thing is the explosion and fire caused by lithium batteries.
For the danger of lithium batteries, it has always been a common topic. With the increase of digital products in people's hands, lithium batteries are just like the same. Mobile phones, MP3s, laptops, and even the most popular mobile power sources, almost all use lithium batteries as internal storage units. Most of the safety accidents caused by lithium batteries are caused by short circuits.
Due to the chemical characteristics of lithium-ion batteries, when we overcharge the battery, because the lithium battery negative electrode can not embed more lithium ions, lithium ions are precipitated as metallic lithium on the surface of the negative electrode, causing the phenomenon of dendritic lithium. When the dendritic lithium grows to a certain extent, it will puncture the diaphragm, causing a short circuit inside the battery, and the isolation film may be damaged, and an internal short circuit may occur, thereby causing a safety accident.
Therefore, when we use lithium batteries daily, we should try to avoid short circuit or overcharge. However, for most digital products, the internal charging circuit will be equipped with corresponding protection IC to avoid overcharging of lithium battery. When the protection circuit detects that the lithium battery has reached the full state, it will automatically cut off the charging circuit. However, I still don't recommend connecting a mobile phone or other device to a charger under power for a long time. After all, no one wants to use his mobile phone or other device or even personal safety to bet with a small charging protection chip.
It is also unwise to pierce a lithium battery compared to short circuits and overcharges. If the lithium battery is pierced by any hard object, the lithium ions inside it will directly react with the oxygen in the air, and the phenomenon of intense combustion will also occur.
So for the lithium battery itself or other electronic products that contain lithium batteries inside, we usually see the eye-catching trash can in the picture above. If the lithium battery is discarded at will, it will not only cause environmental pollution, but also be more prone to fires during the garbage disposal process.
