Anode and cathode material mixing:
material mixing is an important process in battery production. Our mixing machines carry out collection, dissolving, mixing, and storage in one process, ensuring production efficiency and quality. This equipment mixes solvents with a solid mass of 0 to 85%, with the solvent viscosity tested before entering the next step.

Anode and cathode coating:
the coating effect directly impacts the battery capacity, internal resistance, cycle, and safety. Our coating equipment provides a high precision that ensures electrodes are evenly coated.

Compressing by rollers:
1) Ensures the electrode surface is smooth, preventing short circuits caused by burrs on the edges of the foil strips.
2) Compacts the electrode coating material to reduce the size and increase the battery energy density, as well as enhancing the bonding performance to improve the battery service life and safety.

Automatic roll slitting:
cutting the electrodes into small strips. This process includes unwinding, slitting, and rewinding.

Electrode making:
connect the tab material to the electrodes and cut them into the desired shape and size.

Semi-finished battery cell production:
process the electrodes into semi-finished battery cells.

Cell case manufactured with aluminum laminated film:
the aluminum laminated film is stamped and cut into the desired size and shape.

Automatic winding:
after laser cutting, the electrode is wound into a roll-like cell core.

Vacuum baking:
reduce the oxidation of the battery core. In a vacuum environment, lithium battery contamination can be greatly reduced due to the low oxygen content.

Polymer electrolyte injection:
there will be no repeated liquid injection, thus improving the labor efficiency, ensuring an excellent liquid injection consistency and high quality, all while saving energy and reducing consumption.

High temperature curing:
the oxide surface layer of active materials will be reduced under high temperatures, thus improving the reaction between them and lithium ions.

Pre-charging:
3-4 hours after the injection, the electrolyte has fully infiltrated the material on the electrodes and will then charge the cell with a small current. The initial charge allows SEI film (Solid Electrolyte Interface film) to form.

Battery cell assembly:
encapsulate the batteries with the flexible foil to finalize cell production.

Trimming:
during lithium battery production processes, it is necessary to cut off excess scraps to improve appearance and reduce the size.

Battery capacity test:
the battery is charged and discharged through an external power source to test its capacity. Any unqualified batteries are sorted out and removed.

Lithium battery pack assembly:
assemble the battery cell, PCB (Protection Circuit Board) and cable according to customer needs..
