Lithium ion Pouch Cell Assembly for Pouch Battery


 




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.



 





PROCESS 1: Electrode Sheet Preparation


 








































Process Flow

Recommend Equipment

Furnace to sinter raw active material



(Cathode & Anode)



 



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




 





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: 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




 





PROCESS 4: Battery Testing


 
















19: Battery Analyzer to test the pouch cell's performance



20: Battery Impedance Tester to measure battery's internal resistance
