Lithium Polymer Battery Work-Flow

1. Mixing
• Mix solvent and bond separately with positive and negative active materials. Make into positive and negative pasty materials after stirring at high speed till uniformity.

2. Coating


• Coat metal foils uniformly with the made-up pasty materials on two sides. Then make sheets dry.

3. Pressing

• Press the above positive and negative sheets till they become flat.

4. Cutting


• Cut a roll of positive and negative sheet into smaller sheets according to battery specification and punching requests.

5. Pole pieces


• Cut the pole pieces, solder poles, and plate adhesive tape automatically according to technical parameters.

6. Winding


• Separate the positive and negative plate with separator, wind into battery cells along central spindle, and then plate terminate tape.

7. Insulation Test 1

• After separate anode and cathode by separator paper; a battery cell has formed, then test its insulation.

8. Sealing 1


• Seal the upside after putting the naked cell into soft aluminum foil .


9. Sealing 2


• Seal the left side.

10. Insulation Test 2

• Test insulation of the terminal of the battery and the aluminum foil.

11. Insulation Test 3


• Test battery cell's insulation again after sealing.

12. Vacuum Drying


• Dry battery by vacuum, eliminate humid air gas completely, to make sure battery's quality.

13. Electrolyte filling


• Fill with electrolyte in a dry glove box, relative humidity must be under 1%.


14. Sealing 3


• Seal the filling opening in the glove box.


15. Detection
• Test battery's internal resistance and the amount of electrolyte, see if it meets design requirements.

16. Activiting

• Charge and discharge the battery for the first time or more times, connect it to computer, monitor and record its performance indicators.

17. Air exhausting

• Air will exit inside battery after charging, draw it away until vacuum.

18. Sealing 4


• Seal the right side, to insure good sealing performance.


19. Folding


• Cut the redundant soft aluminum foil and fold it automatically with an automatic folding machine.


20. Capacity testing

• Sort batteries according to their capacity with high-precision sorting equipments, which is watched and recorded their performances by computers at all times.

21. Aging testing

• Store batteries in batches in warehouse after inspecting their internal resistance, voltage, capacity and size in the conditions of 10~45℃ and relative humidity of 65±20%. 30 days is needed. Batteries will be re-inspected regularly every 8 days.

22. Assembly


• Assemble according to customers requests after aging. (The assembly ways can be different to meet the customer's requests) . The operator must inspect every batch battery's voltage, internal resistance and all aspect of performance before assembly.

23. Final inspection


• Inspect performance indexes of finished batteries according to GB/ T18287-2000, strictly in accordance with GB/ T2828.1 to make outgoing quality control, every singlebattery must pass sampling inspection before leaving factory.

24. Packaging

• Packaging consists of inner plastic tray and outer double corrugated carton, make them a whole pallet, strap them, wrap with stretch film to insure transportation safety, the packaging comply the regulation of packing storage graphic symbol GB191-1990.
