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 +
|
|
Â
|
8: Ultrasonic Welding Machine to first weld current collector and then tab together
|
|
Â
|
9: Short-circuit Detector to test if the
cell has a short-circuit
|
|
Â
|
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
