As we all know, the battery used by the mobile phone is basically a lithium battery, although the capacity of the nickel hydride battery compared to the early use is greatly improved, but safety is not more than NiMH batteries. 2016 & ldquo; Samsung Battery Gate & Rdquo; Event

According to media reports, there is a problem from a grandfather mobile phone from Deyang, Sichuan. When she repair the phone repair shop, the lithium battery is removed from the curious free hand, and the result is shocked.

As can be seen from the video, the grandfather took a battery in his hand in his hand.Subsequently started with hand, and the resulting battery instantly exploded. And the uncle was obviously scared, and hurriedly put the battery on the ground.

According to the mobile phone store maintenance personnel, the grandfather is coming to the phone. After opening the phone, it is found that the lithium battery has been charged. Uncle seems to be very curious about the old battery of the drum, ask for a look.

At that time, I was clearly told him when I was given to the uncle. I can see it, but I don't want to go.But the uncle watched the battery and watched it, I got it. As a result, the battery exploded and fired.


Of course, as technology matures, now today's lithium batteries have been widely used in various electronic products, electric vehicles, etc. However, due to the cause of the lithium battery itself, there is still an occasional explosion.

At present, the direct incentive of lithium battery fire spontaneously is the thermal out of control of the battery.Simply, the battery is subject to internal short circuit due to various reasons, causing the internal temperature of the battery, and the flammable electrolyte is boiling, sprayed, and bonded to the air.

There are three main causes, mechanical out of control, electrochemical out-of control, and temperature out of control. In mechanical out-of control, the most common is that the battery is crushed or the needle, which can cause the battery diaphragm to pierce the internal short circuit.

There are many reasons for electrochemical out-of control, and the battery quality is an important cause. On the electric vehicle, excessive charging and large current fast charge is an important reason for lure electrochemical out-of control.

The main reason for the loss of control is that the lithium battery is very afraid of heat, if charge and discharge at high temperature, the battery itself will release oxygen and heat. The impact of multiple heat is easy to cause the smelting of the diaphragm, and there is a large area short circuit.
