Lithium batteries have been developed for more than a few decades since their birth. Most of the mobile phones currently on the market are also built with lithium batteries. Although they have been developed for decades, lithium batteries are still not guaranteed to be 100% safe. In the environment, even an explosion will occur.
The most taboo of lithium batteries is the use of conductive sharp objects to puncture the surface, which is very likely to cause an explosion. I have seen the little friends who have seen the wilderness in the wilderness of the wilderness know that Bei Ye often inserts the knife into the lithium battery for fire.
Recently, Weibo netizens shared a small video. A man in the mall used a tooth to bite the battery. He planned to test the battery for true and false, and the result exploded.
In a computer city, a man wants to replace the battery for the mobile phone in front of the counter. He even puts the battery in his mouth and wants to bite and test the authenticity. As a result, the surface of the battery exploded after being punctured, but there were no casualties.
Why does the battery explode?
Both mobile phones and laptops use lithium-ion batteries, which are commonly referred to as lithium batteries. The battery generally uses a material containing lithium as an electrode.
To put it simply, the negative electrode is responsible for storing positively charged ions, and the positive electrode is used for storing negatively charged ions. During the charging process, lithium ions move from the negative electrode to the positive electrode. When the battery is working, lithium ions move in the opposite direction.
The two poles of the battery should never touch each other. Therefore, the battery manufacturer will place a diaphragm between the two poles. If the diaphragm breaks under the influence of external factors, all the energy in the battery will flow to the electrolyte instead of the two poles (electrolysis Liquid is the carrier of ion transport in lithium batteries. The electrolyte itself is a kind of less stable chemical. After receiving too much energy to contact with the outside world, it will generate a lot of heat, and even fire and explosion.
