The cell is typically pre-sealed on three sides. Electrolyte is injected into the open side, and the cell is placed in a vacuum chamber. The vacuum pulls air out of the pouch, and when the vacuum is released, the external atmospheric pressure \"pushes\" the electrolyte into the electrode pores. The key features are: (1) \u003cstrong\u003eVacuum Standing\u003c\/strong\u003e: A chamber where the cell sits under vacuum to allow for degassing and diffusion. (2) Vacuum Sealing Specialized heat-sealing bars that operate inside the vacuum chamber to close the final side of the pouch.\u003c\/p\u003e\n\u003cp\u003eAs for the vacuum electrolyte filling in cylindrical cell, a nozzle creates a tight seal around the cell opening, pulls a vacuum directly from the cell interior, and then injects a precise volume of electrolyte\u003c\/p\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003ctable width=\"100%\" style=\"height: 1196.4px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 47.6px;\"\u003e\n\u003ctd style=\"width: 17.9856%; height: 47.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%; height: 47.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eESMHVEFSM (ESM-HVEFSM)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 10px;\"\u003e\n\u003ctd style=\"width: 17.9856%; height: 10px;\"\u003e\u003cem\u003ePower\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%; height: 10px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eAC110V or 220V±10%, single phase, 50\/60Hz, 1200 W\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 361.2px;\"\u003e\n\u003ctd style=\"width: 17.9856%; height: 361.2px;\"\u003e\n\u003cp\u003e\u003cem\u003eElectrolyte Filling Features\u003c\/em\u003e\u003c\/p\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%; height: 361.2px;\"\u003e\n\u003cul\u003e\n\u003cli\u003ePouch Cell Sizes: Max.
