MRBEST Pouch Cell Assembly Line for Lithium Ion Battery Manufacturing
The below listing is step-by-step guide of how to produce a Li-ion Pouch Cell using MRBEST equipment & materials.
Lithium ion Pouch Cell Assembly for Pouch Battery indicated has various sizes and specifications, therefore can be customized to meet your requirements.
PROCESS 1: Electrode Sheet Preparation
|
Process Flow
|
Recommend Equipment |
|
1. Furnace to sinter raw active material (Cathode & Anode) |
|
| 2. Milling Machine to mill material to smaller particles | |
| 3. Mixer to mix active, conductive and binder material into paste within vacuum | |
| 4. Coater to coat paste onto current collector; attach heater to dry | |
| 5. Rolling Press (Calendar) to roll the electrode to proper thickness | |
| Choose method |
Stacking OR Winding |
|
All consumables & materials are available e.g. Al Film, Metallic Strip Terminal, Tabs |
PROCESS 2: Cell Assembly
|
Procedure
|
Process Flow | Recommend Equipment |
| Stacking | 6: Electrode Die Machine to cut out electrode with lead | |
|
7: Stacking Machine to stack layers in form of Anode + Separator + Cathode + Separator +… |
||
| Winding | 6: Slitting Machine to slit electrode sheet to strip | |
|
7: Winding Machine to wind strips layers in form of Anode + Separator + Cathode + Separator + |
||
| 8: Ultrasonic Welding Machine to first weld current collector and then tab together | ||
|
9: Short-circuit Detector to test if the cell has a short-circuit |
||
| 10: Vacuum Oven to dry the cell if no short-circuit |
PROCESS 3: Case Formation & Sealing
|
Process Flow
|
Recommend Equipment |
|
11: Cup Forming Machine to punch cup- shape and gas receiver on Aluminium lamination sheet and then place cell into the cup |
|
| 12: Top & Side Heat Sealing machine to seal the top and shorter side after double-up | |
| Glove Box: | |
| 13: Electrolyte Filling System to fill electrolyte in vacuum/glove box | |
| 14: Electrolyte Diffusion and Degassing Chamber for De-gas by removing air from the electrolyte | |
|
15: Vacuum Pre-Sealing Machine to seal longer side (the side with gas receiver) under vacuum after electrolyte is filled |
|
| 16. Battery Analyzer to Charge/Discharge the cell for battery formation and drive the unnecessary gas caused by electrode chemical reaction into gas receiver. | |
| 17: Cutting off the gas receiver and Vacuum Sealing Machine for final sealing on the cutting edge under vacuum conditions within glove box |
PROCESS 4: Battery Testing
| 19: Battery Analyzer to test the pouch cell’s performance | |
| 20: Battery Impedance Tester to measure battery’s internal resistance |
