18650 Cylindrical Cell Battery Assembly Line
18650 Cylindrical Cell Battery Assembly Line, designed for both
research and factory labs, is suitable for the production of a wide
range of cylindrical Li-Ion cells, including 18650, 26650, and
21700 formats.
18650 Cylindrical Cell Battery Assembly Line
1. Electrode preparation
Used to prepare the positive and negative electrodes, including
machines for mixing, coating, pressing and drying the electrode
materials and sheets.
2. Battery assembly
Used to assemble the positive and negative electrodes with the
separator to form a battery cell, including machines for winding,
welding, grooving and sealing the battery cases.
3. Electrolyte filling
Used to vaccum the battery case and fill electrolyte.
4. Formation and testing
Used to charge and discharge the battery cell to activate and
stabilize cells and evaluate the performance of final batteries.
