The following is a simplified description of our lithium polymer battery manufacturing process:
1. Mixing
Make a slurry of cathode (positive side) and anode (negative side) electrodes according to the scheme and recipe of the polymer battery model.
2. Coating
Paste is applied to a metal foil (aluminum for cathode, copper for anode). This creates the desired positive and negative plates
3. Cutting
Cut the dried electrode plates to the exact length and width required for the battery cell.
4. Winding
The cathode, anode and diaphragm are wound together. Forms the internal structure of the cell.
5. Injection of electrolyte
Inject electrolyte into the encapsulated cell to allow lithium ions to travel between the positive and negative plates.
6. Sealing & Formation
Encapsulate the cell with an aluminum-plastic film casing to prevent the electrolyte from being exposed. Activate the internal chemical material by charging and discharging.
7. Aging and Testing
Final test of capacity, voltage and overall performance through high and normal temperature aging tests.
