Handles large-volume electrolyte filling with vacuum-assisted infiltration to ensure deep penetration in high-capacity electrodes.
Why this machine: Large cells and thick electrodes require controlled wetting. Vacuum-assisted filling ensures the electrolyte fully penetrates the structure for optimal cycle life.
Ideal User: EV and ESS pouch cell manufacturers.
When to choose: When thick electrodes and high-capacity cells demand deep electrolyte penetration and uniform wetting to support long cycle life and thermal stability.

This section defines the filling operation within large-format pouch cell manufacturing.
Electrolyte is introduced into high-capacity cells in preparation for degassing and enclosure processes.
Packaging focuses on high-capacity filling units and frame stability.
Our core technologies were patented at their inception. Now, as industry standards, we focus on perfecting their reliability and compatibility for you, rather than patent maintenance. This model delivers on that promise.
EV pouch cells typically use thick electrodes and high-capacity designs, making electrolyte wetting more challenging than in consumer cells. This system combines high-accuracy metering with vacuum-assisted filling to ensure uniform electrolyte penetration throughout the electrode structure.
The controlled filling process improves formation consistency, cycle life, and reduces early-stage capacity deviation.
