Pouch Cell Manufacturing Process

• Use furnace to sinter raw cathode active material and anode active material.
• Use milling machine to mill materials into smaller-sized particles.
• Mix active, conductive and binder material into paste under vacuum using mixer.
• Use a coater to coat paste onto current collector to create electrode.
• Use a heater to dry the newly-created electrodes.
• Use the rolling press (calendar) to roll the electrode to required thickness.

Using Stacking Method

• Use Electrode Mould Cutting Machine to cut electrode out with lead.
• Use Stacking Machine to stack layers in the following order: Anode > Separator > Cathode > Separator
• Weld current collector and tab together using Ultrasonic Welding Machine.
• Use a Short-Circuit Detector to test the cell’s integrity.
• Dry the cell using a vacuum oven.

Using Winding Method

• Use Slitting Machine to slice electrode sheet into strips.
• Use Winding Machine to wind strips in the following order: Anode > Separator > Cathode > Separator
• Weld current collector and tab together using Ultrasonic Welding Machine.
• Use a Short-Circuit Detector to test the cell’s integrity.
• Dry the cell using a vacuum oven.

• Use Cup Forming Machine to punch cup and gas receiver on Aluminum lamination sheet and place cell into cup.
• After doubling up, seal the appropriate sides using a Top & Side Heat Sealing machine.
• Use Electrolyte Filling System to fill electrolyte into vacuum/globe box.
• Seal longer side (where gas receiver is located) using a Vacuum Sealing Machine.
• Use Battery Analyzer to charge & discharge the cell. This enables battery formation and sends excess gas to gas receiver.
• Cut off gas receiver and use Vacuum Sealing Machine to finalize sealing on cutting edge under vacuum/glove box.

• Test the newly-created battery’s performance using a Battery Analyzer.
• Use an Impedance Tester to measure the battery’s internal resistance.
