MSK-113-PVL Compact Vacuum Electrolyte Injection System for Large Pouch Cells up to 370x360x12mm
The MSK-113-PVL is engineered to facilitate the controlled injection of liquid electrolyte into large-format pouch cells, addressing the challenges of achieving uniform electrolyte distribution and effective vacuum sealing. It is particularly suited for battery research and development environments where precise electrolyte dosing and airtight sealing are critical for cell performance and safety.
This compact desktop unit integrates vacuum degassing, electrolyte injection, and pouch cell sealing into a single system. It can be operated either inside an argon (Ar) glovebox via a KF40 feedthrough or externally, providing flexibility for various laboratory setups. The system supports pouch cells with maximum dimensions of 370 mm in length, 360 mm in width, and 12 mm in thickness.

구성 및 작동 안내
The MSK-113-PVL requires a double-stage rotary vacuum pump (not included) for vacuum generation. When used inside a glovebox, a KF40 feedthrough facilitates integration. The system needs a supply of high purity inert gas (argon preferred) at 0.5 to 0.8 MPa to operate pneumatic components and maintain a dry atmosphere during electrolyte injection.
Sealing dies should be cleaned after each use once cooled to prevent corrosion from electrolyte residues. Users should consider adding a high-precision digital balance inside the chamber to monitor electrolyte loss caused by vaporization during vacuum injection. Proper installation of a two-stage pressure regulator is necessary if using a gas cylinder instead of an air compressor to ensure safe operation.
