Can soft lithium batteries be discharged if punctured?

Hello, I am happy to answer your question.

If the outer skin of the lithium battery is broken, it is easy to leak electricity and suffer electric shock. It is best to replace it with a new one.

Soft-packaged lithium batteries are simply liquid lithium-ion batteries covered in a polymer shell. The main materials used in soft-packaged lithium batteries (positive electrode materials, negative electrode materials and separators) are different from those of soft-packaged lithium batteries. traditional steel enclosures. There is not much difference between aluminum shell lithium batteries and aluminum shell lithium batteries. The biggest difference lies in the flexible packaging material (aluminum-plastic composite film), which is the most critical and technically difficult material to manufacture. -pack batteries to bedhium. The structure of soft lithium batteries uses aluminum-plastic film, which is a three-layer structure. If only the outermost plastic film is damaged, it can still be used, but the injured part must be protected if the aluminum film is. damaged, battery life will be affected, and even there is a safety risk; if the three-layer film enters the battery, it will be scrapped and cannot be reused.

There will be a leak. If the battery skin is shorted, it will also leak internally, whether it is a 18650 or a hard or soft packaged large cell, except the positive electrode . terminal, the small piece is the positive electrode. You can take off from other places. Open the outer cover and use a voltmeter to measure it. If the battery itself is leaking, it's basically useless and throw it away. If there is no problem with thebattery itself, regardless of whether the positive and negative poles are disconnected. The same goes if the switch is off. However, because the battery itself has internal resistance, there is a very small current self-discharge phenomenon, so it needs to be recharged after a period of time. It does not need to be recharged, it only takes a few minutes. 22 lithium manganese oxide cells that can be fully charged for 4 months. It doesn't even lose much power, and the discharge test when fully charged doesn't lose capacity~
