The prismatic lithium battery production line is used to manufacture metal-cased prismatic lithium-ion batteries, primarily for electric vehicles and energy storage systems. This production line emphasizes high energy density and structural stability, employing advanced stacking or winding processes. The produced batteries feature good consistency and long cycle life, meeting the demands of high-end markets.

3: Process Flow:

1. Slurry Preparation (Mixing)

2. Prepare high-quality positive and negative electrode slurries, ensuring uniform distribution of active materials.

3. Coating

4. Use precision coating equipment to evenly apply slurry onto current collectors, forming electrode sheets.

5. Drying and Calendering

6. Dry to remove solvents, and calendar to adjust electrode thickness and density, improving battery performance.

7. Slitting

8. Precisely cut electrode sheets to designed sizes, preparing for stacking or winding processes.

9. Stacking or Winding

10. Stacking process: Layer positive electrodes, separators, and negative electrodes in sequence to form the cell core.

11. Winding process: Wind electrode sheets into a flat spiral cell core.

12. Assembly

13. Insert the cell core into a prismatic metal casing, weld tabs, and install safety units such as explosion-proof valves.

14. Electrolyte Filling

15. Inject electrolyte into the cell in a clean environment, ensuring consistency.

16. Sealing

17. Seal the battery using laser welding or riveting methods to ensure airtightness.

18. Formation and Grading

19. Perform formation and capacity testing to screen qualified products.

20. Testing and Packaging

21. Conduct electrical, mechanical, and safety performance tests. Package qualified products for shipment.
