Today after a whole day hard work,we finally finished the five containers equipment for pouch cell pilot line to Russia. Good weather and good project.

Pouch cell electrode making is same as other model electrode,it is mainly different at the assembly.From electrode stacking to sealing.

Stacking

After the production of the electrode, it is transferred to the stacking. The stacking means that the cathode, the separator, and the anode are stacked layer by layer to make a jolly roll. There are two main stacking methods, winding and zigzag stacking.

Aluminum laminated film forming

Punching, punching is a forming process for Aluminum laminated film. After feeding the aluminum-plastic film, the aluminum-plastic film is deformed through the punching die, and there is a pocket for us to store the core.

Pre-sealing

There are a total of four packages. The pre-package we mean refers to the top and side seals, leaving a seal to facilitate electrolyte injection. After placing the core in the pit, the entire aluminum-plastic film can be placed in the jig for top sealing and side sealing in the top side sealing machine. When encapsulating, the two heads have a certain temperature (generally around 180 ℃), and when pressed, they are pressed on the aluminum plastic film, and the PP layer of the aluminum plastic film melts and then sticks together.

Second-sealing

During the second seal, the air bag is punctured by a guillotine and a vacuum is drawn at the same time, so that the gas in the air bag and a small part of the electrolyte will be drawn out. Immediately afterwards, the two sealing heads are encapsulated in the second sealing area to ensure the airtightness of the cell. Finally, cut off the airbags after the packaged cells. After the second airbags are cut, you need to trim and fold the edges. That is, cut the one edge and the second edge to a suitable width, and then fold it to ensure the battery core. The width does not exceed the standard, such a soft-packed battery core is basically formed.

We, TOB New Energy ,we are not only provide the battery equipment , but also provide the battery technology.
