You are truly ignorant and fearless.
The temperature is too high: the electrolyte decomposes and the cathode material decomposes. Among them, the cathode material composed of ternary lithium cobalt oxide decomposes, which will produce a large amount of oxygen and explode.
The discharge current is too large: the internal heat cannot be dissipated, which will cause heat accumulation and excessive temperature. The electrolyte decomposes slowly at 70-80 degrees. When a general battery is discharged to 3°C, a temperature increase of 15 to 20 degrees is normal. The higher the rate, the greater the temperature increase. Batteries of different designs have very different temperature rises.
Overdischarge: The base copper foil of the negative electrode will migrate to the positive electrode at a low potential, causing the copper to precipitate on the electrode.positive ctrode. The crystal structure of the positive electrode is destroyed and a. A layer of copper is deposited on the surface of the electrode. Serious direct The positive and negative electrodes are connected, not to mention the SCI membrane. It will also make you angry.
As for the wires you said are flexible, each wire specification has a current carrying capacity. Under different currents, there is also an increase in temperature and you should do it next to the TV. Next time, maybe Baidu will have the video of the lithium battery explosion first.
