Polymer battery is one of the common new energy batteries, but when manufacturing polymer battery, it will also tell you the wrong operation of polymer lithium battery. The following operation method is wrong.

1. The aluminum-plastic film on the surface of the polymer battery cannot be maliciously damaged, nor can it be operated with a ribbon cutter:

If it is on the production line, the on-site operator cannot use the soldering iron to iron the surface of the battery unit.

2. Do not intentionally break the terminal lug, especially the positive pole of the lithium battery. The mechanical strength of the splice is not very high, and it is easy to break. Do not bend the label.

3. Do not intentionally damage the top seal of the lithium battery. The author warns that the top gasket is easily damaged and causes delamination, so bending the top gasket is prohibited.

4. Do not intentionally damage the bottom of the battery side. The side seal was folded and fixed during the formation of the battery, and passed the sealing test. Repeated opening and bending may cause the aluminum foil to break. It is forbidden to open or damage the hem.

Fifth, the contacts of the battery cannot squeeze the corners of the lithium battery, and the corners are also very weak, which is particularly prone to leakage.

Sixth, the battery contacts cannot bend the surface of the battery, which may cause an internal short circuit.

7. Do not touch the positive and negative poles of the battery to metal objects. If the battery unit is short-circuited, it will seriously damage the battery unit and may even cause a safety accident.
