1. Aluminum-plastic composite film outer packaging protection: mainly to avoid being damaged by sharp parts. For this reason, the surrounding environment of the battery should be cleaned up from time to time, sharp parts are forbidden to touch or collide with the battery cell, and gloves can be worn when taking it to avoid scratching the surface of the battery cell with fingernails.

2. Pole handle protection: The positive lead terminal of the polymer lithium battery cell adopts an aluminum pole handle, and the negative lead terminal uses a nickel pole handle. Since the pole handle is thin, bending should be prohibited; at the same time, the pole handle and the aluminum-plastic composite film should be avoided in the production process, and the ferrule film should be strictly isolated.

3. Avoid mechanical impact, such as falling, hitting, bending the battery cell and accidentally trampling on the battery.

4. Waterproof protection: The lithium battery is assembled, and the whole is poured with insulating glue before packaging. Or choose a waterproof battery box.

5. Do a good job of heat dissipation, and use a thermal conductive silicone grease pad as a medium to guide the heat to the stainless steel housing. Or the battery pack has conditions to provide a heat conduction channel, and during energy conversion, timely heat conduction can optimize the battery. Steel outer box + fan assist, both are conventional solutions.

6. The transfer of the positive aluminum pole handle through the nickel strip and the connection between the battery core and the circuit board should be implemented by ultrasonic welding or spot welding technology.

7. Reliable positioning of the battery cell. After the battery cell is assembled, it should be fastened firmly in the shell, and will not loosen at will, so that the entire lithium battery structure is in a consolidated state.
