• Production Line

1. Mixing

   • English: Active materials (cathode: LiCoO₂/LiFePO₄; anode: graphite), conductive agents, and binders (e.g., PVDF) are mixed with solvent (NMP or water) to form homogeneous slurry.
     

2. Coating

   • English: Slurry is uniformly coated onto metal current collectors (Al foil for cathode, Cu foil for anode) via coating machine, with controlled thickness and areal density.
   • 
   • 
     
   • 
3. Drying
   
   • Wet coating is dried in ovens to evaporate solvent, forming porous electrode structure.
   • 

4. Calendering

   • Dried electrodes are compressed by calendering rolls to enhance energy density and mechanical strength.
   • 
   • 

5. Slitting

   • Wide electrodes are slit into narrow strips matching cell dimensions.
   • 
   • 

6. Tab Welding

   • Metal tabs (Al for cathode, Ni for anode) are ultrasonically welded to current collectors.
   • 
   • 

7. Winding

   • Anode, cathode, and separator (PP/PE) are wound into "Jelly Roll" structure with controlled tension and alignment.
   • 
   • 

8. Assembly

   • Wound core is inserted into steel/aluminum case with insulating gaskets.
   • 
   • 
   • 

9. Electrolyte Injection

   • Electrolyte (LiPF6/organic solvent) is injected in dry room to wet electrodes and separator.
   • 

10. Sealing

    • Cell is sealed via laser welding or crimping to prevent leakage.
    • 

11. Formation

    • Initial charging activates the cell and forms SEI layer (on anode).
    • 

12. Aging

    • Cells rest to stabilize chemical properties.
    • 

13. Testing

    • Tests include voltage, IR, capacity, cycle life, and safety (e.g., nail penetration, overcharge).
    •
