Jingtong Battery Equipments provides both standard and custom-made products and solutions to meet customers' specific requirements for battery manufacturing. For pouch cell fabrication, we offer various equipment for electrode sheet preparation, cell assembly and battery case formation and sealing.

The pouch cell consists of repeated stacks of multiple layers components which are enclosed in an aluminum laminated film case. After electrode sheets preparation and cell assembly, the last step is case formation and sealing. Here is the process overview:

- Prepare the cell case on aluminum laminated film using case forming machine and place the cell in the case.

- Seal the case using top & side heat sealing machine.

- Inject electrolytes into the cell.

- Seal the case using vacuum sealer.

Jingtong Battery Equipments offers equipment for Pouch Cell Case formation and sealing including case forming machines, top& side Heat Sealing Machines and Vacuum Sealers.

Case Forming Machine

Jingtong Battery Equipments offers a Benchtop Pneumatic Aluminum Laminated Film Case Forming Machine. It is widely used to prepare pouch cell cases made of aluminum laminated film. If you need to customize the maximum die size, please email us at [email protected].

Top & side heat sealing machine

Jingtong has Benchtop Pouch Cell Aluminum Laminated Film Case Top and Side Sealer. It is widely used to seal the side and top with tabs before electrolyte injunction. If you need to customize the sealing size and width, please email us at [email protected].

Vacuum Sealer

Jingtong also offers Glovebox Compatible Benchtop Heating Vacuum Sealers.  It can be used for pouch cell case top/side sealing, vacuum standing for electrolyte diffusion and degassing, and vacuum sealing after Electrolyte Injection.

In recent pouch cell research article (Schmiegel et al. 2020), our Vacuum Sealer was used for pouch cell fabrication. In this study, the author incorporated a gas sampling port (GSP) in a commercial pouch cell for measuring gas formation and evaluated the cell setup for electrolyte additive research. This GSP setup is able to extract only small amount of gas without significantly influencing the cell performance.
