Complete Production Process Flow

  • Electrode Preparation 

Battery materials are mixed into slurry, coated onto metal foil, dried and calendered to achieve the required electrode thickness and density.

  • Electrode Slitting

Coated electrodes are cut into precise widths suitable for specific cell formats.

  • Cell Assembly

Electrodes and separators are wound (cylindrical) or stacked to form the internal core.

  • Welding & Insertion

Tabs are welded, and the cell core is inserted into the casing to ensure structural integrity.

  • Electrolyte Filling

Electrolytes are injected under controlled conditions to enable ion transport inside the cell.

  • Sealing & Vacuum Drying 

Cells are sealed and dried to remove moisture and contaminants.

  • Formation & Aging

Cells undergo initial charge/discharge cycles to stabilize internal chemistry and form the SEI layer.

  • Testing & Grading

Final cells are tested for capacity, voltage, resistance, and safety, then sorted by performance grade.
