What are the methods for assembling soft-pack lithium batteries?

Soft-packed lithium battery packaging method Aluminum-plastic film forming process The soft-packed lithium battery can be designed into different sizes according to customer needs. When the external dimensions are designed, the corresponding mold must be opened to form the aluminum-plastic film. Sometimes, according to the design requirements, a small hole is punched in the position of the air bag to expand the volume of the air bag. Top-side sealing process The top-side sealing process is the first packaging process for soft-packed lithium batteries. The top side seal actually includes two processes, the top seal and the side seal. First put the wound core into the punched pit, and then fold the packaging film in half along the dotted line. After the core is placed in the pit, the entire aluminum plastic film can be placed in the fixture, and the top and side sealing are performed in the top side sealing machine. After the liquid filling and pre-sealing process, the soft-packed batteries are sealed on the top side, X-ray is required to check the parallelism of the cores, and then go into the drying room to remove moisture. After a certain period of time in the drying room, it enters the liquid injection and pre-sealing process. After the cell is sealed on the top side, there is only one opening on the air bag side, and this opening is used for liquid injection. After the liquid injection is completed, the pre-sealing of the side of the air bag should be performed immediately, which is also called one. After a package is completed, the core is theoretically completely isolated from the external environment.
