|
|
15: Vacuum Primary-Sealing Machine to seal longer side (the side with gas receiver) under vacuum after electrolyte is filled |
|
|
Battery Analyzer to Charge/Discharge the cell for battery formation and drive the unnecessary gas caused by electrode chemical reaction into gas receiver. |
|
|
17: Cutting off the gas receiver and Vacuum Sealing Machine for final sealing on the cutting edge under vacuum conditions within glove box |
|
PROCESS 4: Battery Testing
|
19: Battery Analyzer to test the pouch cell's performance |
|
|
