Pouch Cell Manufacturing Process

Step 1: Preparation of the electrode

1. The cathode active material and anode active material were sintered in heating furnace.
2. A milling machine is used to grind the material into smaller particles.
3. In a blender, the active material, the conductive material, and the adhesive are mixed in a vacuum to form a paste.
4. The paste is applied to the collector by a coater to produce an electrode.
5. Use a heater to dry the newly made electrodes.
6. Use a roller (calendar) to roll the electrode to the desired thickness.

Step 2: Assemble the lithium-ion battery

Use the stack method

1. Lead electrode is cut out by electrode die - cutting machine.
2. Stacker shall be used in the following order: anode & GT; Separator in the cathode message separator
3. Use ultrasonic welder to weld the collector and patch together.
4. Use a short circuit detector to test battery integrity.
5. Dry the batteries in a vacuum oven.

Use the winding method

1. Use a strip cutter to cut the electrodes into strips.
2. Winding sequence of using winding machine: anode & GT; Separator in the cathode message separator
3. Use ultrasonic welder to weld the collector and patch together.
4. Use a short circuit detector to test battery integrity.
5. Dry the batteries in a vacuum oven.

Step 3: Form and seal the battery case

1. Punch the cup and the gas tank on the aluminum sheet with a cup maker and place the battery in the cup.
2. After folding, seal the appropriate side with the top edge heat seal machine.
3. Fill the vacuum/sphere box with electrolyte filling system.
4. Seal long edges (gas receiver location) with vacuum sealer.
5. Use the battery analyzer to charge and discharge the battery. This allows the battery to form and sends excess gas to the gas receiver.
6. Under the vacuum/glove box, cut off the gas collector and seal the cutting edge with a vacuum sealer.

Step 4: Battery test

1. Use the battery analyzer to test the performance of the newly created battery.
2. Use an impedance tester to measure the battery's internal resistance.
