The primary challenge during the electrolyte wetting step is that modern dense, highly compacted electrodes (especially polyanionic cathodes like NFPP or ultra-high nickel NCM layers) feature extremely tight pore networks. Injecting electrolyte under standard atmospheric conditions traps air pockets within the cell stack, resulting in dry areas, high local current hotspots, and premature capacity fade.\u003c\/p\u003e\n\u003cp\u003eThe vacuum electrolyte injection \u0026amp; standing machine normally includes the following procedures: (1) \u003cstrong\u003ePre-Evacuation (Vacuuming)\u003c\/strong\u003e: The assembled pouch or cylindrical cell is placed into the machine's sealed working chamber. The system draws a deep vacuum (typically -90 to -95 kPa), extracting all trace air and ambient moisture from the internal electrode folds and separator pores. (2) \u003cstrong\u003ePrecision Micro-Injection\u003c\/strong\u003e: While remaining under vacuum, a high-purity ceramic rotary metering pump delivers a precisely metered volume of electrolyte into the cell. (3)\u003cstrong\u003e Vacuum Standing \u0026amp; Diffusion (The Pressure Swing)\u003c\/strong\u003e: The machine enters its programmed standing phase. It toggles between deep vacuum levels and controlled atmosphere venting (often using an inert gas like Argon). This pressure swing mechanism utilizes capillary action to forcefully drive the liquid electrolyte deep into the micro-pores of the electrodes, achieving maximum wetting. \u003c\/p\u003e\n\u003ctable width=\"613\" style=\"height: 670.062px; width: 109.308%;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 58.4625px;\"\u003e\n\u003ctd style=\"width: 22.3022%; height: 58.4625px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 77.518%; height: 58.4625px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eERPCCVEISM (ER-PCC-VEISM)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 47.6px;\"\u003e\n\u003ctd style=\"width: 22.3022%; height: 47.6px;\"\u003e\u003cem\u003ePower\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 77.518%; height: 47.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eAC110V or 220V±10%, single phase, 50\/60Hz, 500 W\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 243.6px;\"\u003e\n\u003ctd style=\"width: 22.3022%; height: 243.6px;\"\u003e\u003cem\u003eVacuum Electrolyte Injection Features\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 77.518%; height: 243.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eTwo main functions: vacuum electrolyte injection and standing\u003c\/li\u003e\n\u003cli\u003eVacuum chamber frame is made of aluminum and all other critical parts, especially for electrolyte contact area is SS316 L)\u003c\/li\u003e\n\u003cli\u003eDuration setting: Max. 9999 min\u003c\/li\u003e\n\u003cli\u003ePouch Cells: L20-240 mm * W20-240 mm, T0-15 mm\u003c\/li\u003e\n\u003cli\u003eCylindrical Cells, 18650, 21700, 26650, and 32650\u003c\/li\u003e\n\u003cli\u003eSample fixture with Selven slots that can be switched by rotating the wheel.
