Will lithium polymer batteries explode?

The current lithium polymer batteries are mostly soft pack batteries, using aluminum plastic film as the outer shell. When the organic electrolyte is used inside, it will not explode even if the liquid is hot, because the aluminum plastic film polymer battery adopts solid or colloidal state without leakage. , Just broken naturally. But nothing is absolute. If the instantaneous current is large enough and a short circuit occurs, it is not impossible for the battery to spontaneously ignite or burst. The occurrence of mobile phone and tablet safety accidents is mostly caused by this situation. In a low-temperature environment, the low-temperature protection mechanism of polymer lithium batteries will promote chemical reactions that do not occur in the battery, so that it cannot be charged or the charging speed is slowed down. At high temperatures, the battery will be unstable and even cause an explosion. Lithium polymer batteries are again known as polymer batteries. Compared with the lithium battery, the biggest difference in safety is that when the two batteries are heated to a certain extent, the lithium battery will explode, while the lithium polymer battery will only undergo chemical volatilization, and at most it will burn. Never explode. From the structural point of view, polymer batteries generally use soft packaging with thinner and softer shells. Lithium batteries mostly use hard packaging with thicker and harder shells. From a safety point of view, once the soft-packaged battery is suddenly damaged, such as charging voltage The explosion caused by too high and too high temperature is far less destructive than a hard-packed lithium battery.
