Compact Vacuum Electrolyte Injection System for Large Pouch Cell (Max. L370*W360*T12mm) - MSK-113-PVL

Advanced Features

• Vacuum liquid electrolyte injection for large pouch cell with the programable setting via the touchscreen controller.
• Pouch cell vacuum sealing, electrolyte injection, vacuum standing three-in-one design
• It could be used either in or outside of the glove box
• Electrolyte injection speed adjustable
• The electrolyte filler with a speed control console and injection pump for the high-precision dispensing is integrated into the system
• Electrolyte injection could be done under different vacuum levels in order to achieve a better electrode immersion
• Compact & desktop; One unit with PLC control

• Either AC110 V or AC208-240 V, 50/60 Hz, single phase
• Power: 1.4 KW

Working Gas

• 0.5~0.8 Mpa high purity compressive inert gas (Ar is preferred) is required for driving the pneumatic system in the glove box
• Continues dry inert gas purging for the working chamber is required to maintain a dry atmosphere for electrolyte injection and diffusion 
• Air compressors and fitting are required if used in the dry room, but not included. 
• Attention: If a gas cylinder is used instead of an air compressor(pic2), a two-stage pressure regulator(pic1) must be installed on the gas cylinder to limit the pressure within the required working range for safe operation. Click here to learn the installation of a gas regulator

• A peristaltic pump is used to precisely transfer electrolyte to large pouch cell; Injection Accuracy: 1%
• During the electrolyte injection and vacuum standing under the vacuum, liquid electrolytes would be vaporized. Please consider refilling the electrolyte if necessary
• Electrolyte filling volume and injection rate adjustable via touch screen PLC control

• Pouch cells: Max. L 370 mm * W 360 mm * T 12 mm

• Vacuum Degassing:
• Vacuum range: -95 ~ 0 kPa adjustable
• Dwell Time: 0~99 seconds adjustable
• Inert gas filling:
• Max. pressure: 110 Kpa max. adjustable
• Dwell Time: 0~99 seconds adjustable
• Sealing Temperature and time:
• Two digital temperature controllers on the front panel provide independent control for the left and right heating dies.
• Temperature range: 25 ~ 220 ℃ adjustable (accuracy ± 3 ℃)
• Recommended sealing temperature: 180~190 ℃
• Sealing time: 0 ~ 99 seconds adjustable (5 ~ 6 seconds is recommended)
• Electrolyte injection: 
• 0.3 ml - 100 ml programmable under normal atmosphere
• Injecting under vacuum or inert gas selectable

• Sealing width: 2-10 mm (6 mm is the standard one)
• Sealing accuracy: ~0.03 mm

• Maximum sealing pressure: 70 kg*f (~0.6 MPa)

• PTFE tubing: O.D. = Φ3m, I.D. = Φ2m for peristaltic pump
• O.D 8mm gas tubing for compressed gas inlet and outlet
• O.D 10mm gas tubing for vacuum pumping and vacuum release
  

• 300 mL

Vacuum Pump (not included)

• Double-stage rotary vacuum pumps are needed for vacuum diffusion and degassing and vacuum sealing. Please click the picture below to purchase separately.

• NRTL Certification is available upon request at an extra cost
•  the patent 201822101349.0 for the Pouch Cell Sealing Machine integrated with Electrolyte Injection MSK-113 since December 2019

• Please clean the sealing dies after each use. Clean the sealing die after it has cooled down to avoid corrosion by the electrolyte.
• The featured air-tight chamber enables the operation under the Ar atmosphere where Lithium-Sulfur, Lithium Air, Lithium Solid-State, will be assembled. Please click the images below to understand these technologies and how it fits in a glove box.
• Please add the high-precision digital balance to the chamber in order to monitor and evaluate the liquid electrolyte lost during the vacuum electrolyte injection. Because there might be some liquid electrolyte evaporation caused by the pressure difference between the liquid electrolyte tank and vacuum chamber.
