{"product_id":"erccaeivsm","title":"ECS-R Ambient Electrolyte Injection \u0026 Vacuum Standing Machine with Dual Chamers for Cylindrical Cells, ERCCAEIVSM","description":"\u003cp\u003eAn Ambient Electrolyte Injection \u0026amp; Vacuum Standing Machine is a critical piece of hardware in cylindrical cell assembly lines (such as 18650, 21700, or 4680 formats). Its primary purpose is to precisely dose the highly volatile, sensitive electrolyte into the cell casing under ambient pressure, and then use cyclic vacuum holding (standing) to force the liquid into the tightly wound jellyroll.\u003c\/p\u003e\n\u003cp\u003eThe process is generally divided into two distinct chambers or sequential modules: the Injection Station and the Vacuum Standing Station.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLiquid Injection Stage\u003c\/strong\u003e: (1) \u003cem\u003ePrecision Dosing\u003c\/em\u003e: High-precision ceramic pumps (often utilizing linear motors or stepping motors) measure the exact electrolyte volume, typically within an accuracy of ±0.5% to ±1%. (2) \u003cem\u003eAmbient Control\u003c\/em\u003e: While injection occurs at atmospheric\/ambient pressure within the machine, the environment inside the chamber is strictly maintained with an ultra-dry atmosphere (typically a dew point below -40°C to -60°C) to prevent the electrolyte (LiPF6 or NaPF6) from reacting with moisture to form highly corrosive hydrofluoric acid (HF). (3) \u003cem\u003eAnti-Drip Nozzles\u003c\/em\u003e: Specialized vacuum-suction nozzles prevent any residual drops from contaminating the cell rim, which would interfere with the subsequent cap welding\/sealing process.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eVacuum Standing Stage (Wetting)\u003c\/strong\u003e: Because cylindrical cells feature a tightly wound jellyroll (cathode, anode, and separator compressed together), the electrolyte cannot easily permeate the core via gravity alone. (1) \u003cem\u003eAir Evacuation\u003c\/em\u003e: The machine seals the cell cup and draws a vacuum. This evacuates the micro-voids and air pockets trapped between the electrode layers and the separator. (2) \u003cem\u003ePressure Differential Drive\u003c\/em\u003e: By abruptly breaking the vacuum or cycling between vacuum and atmospheric pressure, a strong pressure differential forces the electrolyte deep into the pores of the electrodes and the separator framework. (3) \u003cem\u003eMulti-Stage Stepped Vacuum\u003c\/em\u003e: Advanced machines utilize a programmable, multi-stage profile (e.g., pulling down to -95 kPa, holding, bumping to -50 kPa, and returning to 0 kPa) to accelerate complete wet-out without causing the electrolyte to boil or froth.\u003c\/p\u003e\n\u003ctable width=\"613\" style=\"height: 1004.46px;
