Lithium ion Pouch Cell Assembly for Pouch Battery
Â
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 customised to meet your requirements.
Â
PROCESS 1: Electrode Sheet Preparation
Â
Process Flow | Recommend Equipment |
Furnace to sinter raw active material (Cathode & Anode) Â |
|
Milling Machine to mill material to smaller particles |
|
Mixer to mix active, conductive and binder material into paste within vacuum |
|
Coater to coat paste onto current collector; attach heater to dry |
|
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 |
|
Â
PROCESS 2: Cell Assembly
Â
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 |
|
Â
PROCESS 3: Case Formation & Sealing
Â
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: De-gas by removing air from the electrolyte |
|
15: Vacuum Primary-Sealing Machine to seal longer side (the side with gas receiver) under vacuum after electrolyte is filled |
|
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 |
|
Â
PROCESS 4: Battery Testing
Â
19: Battery Analyzer to test the pouch cell's performance |
|
20: Battery Impedance Tester to measure battery's internal resistance |
