Can pouch polymer lithium-ion batteries burn and explode?

Pouch polymer lithium-ion battery is a new type of battery with a variety of distinct advantages, such as high energy density, miniaturization, ultra-thinness, light weight, and high safety. In terms of shape, lithium polymer batteries have the characteristics of ultra-thinness, which can be made into batteries of any shape and capacity according to the requirements of various products. The minimum thickness that can be achieved by this type of battery can be as small as 0.5mm, and there is no memory effect.

Pouch polymer lithium-ion battery is a lithium-ion battery product made of flexible packaging and polymer electrolyte, which will not explode when used and stored under normal circumstances, unless it is short-circuited due to strong destruction. The current polymer lithium-ion battery is mostly a pouch battery, using aluminum-plastic film as the shell, when the organic electrolyte is used inside, even if the liquid is very hot, it does not explode, because the aluminum-plastic film polymer battery uses solid or gelatinous state without leakage, but naturally broken.
But nothing is absolute, if the instantaneous current is large enough to cause a short circuit, it is not impossible for the battery to spontaneously combust or burst, and the occurrence of mobile phone and tablet safety accidents is mostly caused by this situation.

The correct way to charge polymer lithium-ion batteries

1. Please confirm the temperature when charging
In a low-temperature environment, the low-temperature protection mechanism of the polymer lithium-ion battery will promote the chemical reaction of substances in the battery, so it cannot be charged or the charging speed is slowed down, and at high temperatures, the battery will be unstable and even cause an explosion!

2. Pay attention to the number of charging and frequent charging
There is a saying: each mobile phone battery has a fixed number of charges, if the number of charging times is too much, it will accelerate the degree of battery aging and strain! In fact, this is wrong, frequent charging is actually slightly good for the battery!
