- Use a Short-Circuit Detector to test the cell’s integrity.
- Dry the cell using a vacuum oven.
Step 3: Formation & Sealing of Battery Case
- Use Cup Forming Machine to punch cup and gas receiver on Aluminum lamination sheet and place cell into cup.
- After doubling up, seal the appropriate sides using a Top & Side Heat Sealing machine.
- Use Electrolyte Filling System to fill electrolyte into vacuum/globe box.
- Seal longer side (where gas receiver is located) using a Vacuum Sealing Machine.
- Use Battery Analyzer to charge & discharge the cell. This enables battery formation and sends excess gas to gas receiver.
- Cut off gas receiver and use Vacuum Sealing Machine to finalize sealing on cutting edge under vacuum/glove box.
Step 4: Battery Testing
- Test the newly-created battery’s performance using a Battery Analyzer.
- Use an Impedance Tester to measure the battery’s internal resistance.
