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
