What Is a Pouch Cell Winding Machine?
A pouch cell winding machine winds anode, cathode, and separator into a jelly roll for soft pack lithium‑ion batteries. It ensures precise alignment and consistent tension, directly affecting cell performance and safety. Our machine supports both cylindrical and flat winding for pouch cells, with quick changeover between different cell sizes.
High Speed Pouch Winder – Performance & Key Features
This battery winding machine achieves a winding speed of up to 12m/min, significantly increasing throughput while maintaining accuracy. Key features include:
Closed‑loop tension control – Constant tension on separator and electrode strips.
Automatic tape termination – Secures the finished jelly roll without manual intervention.
High uptime – 98% OEE, 99.5% yield.
The high‑speed design reduces cycle time per cell, making it suitable for high‑volume production lines.
