The mobile phone, the notebook is used by a lithium ion battery. The lithium ion battery is a device that relies on the movement of lithium ions on the positive and negative poles to supply the power supply to the device to be released. Do not add other influencing factors.

From a technical point of manufacture, this design is fully implemented, but during practice, due to the lithium ion battery is a very strong product, any abnormal situation may cause problems in the battery. All lithium-ion battery explosions are caused by short circuits, causing short circuits, overcharge, overlapping, overcurrent, overheating, is a battery short circuit through the internal structure of a lithium ion battery, the so-called internal cause of determining the meaning, The lithium-ion battery structure itself is a process manufacturing process, and the process manufacturing process is difficult to 100% alert. The positive and negative of lithium ion should be clean, the electrolyte between the intervals, the diaphragm should also have impurities, but in the manufacturing process, the electrolyte and the separator are difficult to completely guard against metal dust, copper foil or aluminum foil and other debris.

When people use improper (overcharge, overflow, overcurrent) or put the lithium-ion battery in extreme environments (too high temperature), the lithium-ion battery will overheat, the fragment is broken at room temperature, which will be Hot movement in a more hot electrolyte space. Next, if the fragment is close to the diaphragm, hot debris will affect the isolation use of the diaphragm, it also causes short circuits. It can be seen that the short circuit is due to the two originals: First, there is impurities in the battery, and the second is the exercise of the impurity.

Therefore, the intermediary is fever. Therefore, the short circuit must have fever accompanied, and heat is not necessarily short circuit. In the third step, the short circuit will burst spark, and the electrolyte is flammable, sparking will cause the battery's burning and explosion in a closed space, which is easy to understand.

Therefore, there is a polymer lithium-ion battery instead of liquid electrolyte by colloidal electrolyte, and can reduce the probability of short circuit. But you can't completely alert. Once the battery is short-circuited, the battery structure and temperature are different.

In general, the battery has three cases of leakage, combustion, and explosion, and the safety problems caused by combustion are the most serious.
