lab Research pouch cell battery making process

Step Process Recommended equipment
Electrode preparation 1. Mix and grind the prepared powder materials. Ball Mill
2. Mixing the prepared positive and negative electrode materials under vacuum. Mixer
3. Use a viscometer to measure the viscosity of the slurry. Viscometer
4. Use iron removal filtration equipment to filter the slurry. Filter
5. Coat the positive and negative electrode materials on the current collector respectively and dry them.

Coater

6. Calender the positive and negative electrode sheets to reduce the thickness and increase the density. Calendering Machine
Battery Cell Preparation Stacking process 1. Cut the electrode into rectangular sheets of specified size. Die Cutting Machine
2. Stack the positive and negative electrode sheets and separator in order (separator + positive electrode + separator + negative electrode). Stacking Machine
Winding process 1. Cut the electrode and separator into long strips of specified width. Slitting Machine
2. Stack the positive and negative electrode sheets and separator in order (separator + positive electrode + separator + negative electrode). And then start winding them to make battery cells. Winding Machine
Battery tabs and current collector welding 1. Use an ultrasonic spot welder to weld the battery tab and current collector. Ultrasonic Spot Welder
2. Measure whether the battery cell is short-circuited. Short circuit tester
Battery cells drying Place the battery cells in a vacuum drying oven for drying. Vacuum Drying Oven
Battery Assembly Process 1. Aluminum laminated film pouch cell case forming. Place the cells into the formed aluminum laminated film. Pouch Cell Case Forming Machine
2. Heating sealing the top and side of the aluminum laminated film. Top and Side Sealing Machine
3. Move the battery ccells into the glove box. Glove Box
4. Filling an appropriate amount of electrolyte into the battery cells in the glove box. Electrolyte Filling Machine
5. Place the battery cells into the vacuum diffusion chamber in the glove box. A vacuum diffusion chamber is used to fully infiltrate the battery electrodes with the filled electrolyte. Vacuum Diffusion Chamber
6. Use a vacuum pre-sealing machine to seal the cells in the glove box. Vacuum Pre-Sealing Machine
7. Charge and discharge the battery 3 times to activate the battery, then puncture the air bag to discharge the gas and excess electrolyte. Formation Machine
8. Complete the secondary sealing of the cells in the glove box. Vacuum Sealing Machine
9. Cut off the excess edges of the aluminum laminated film casing of the cells and fold the edges. Trimming Machine
Battery testing 1. Use battery tester to test the capacity and cycle tests. Battery Tester
2. Use an internal resistance tester to measure the internal resistance of the cells. Internal Resistance Tester
