Precision semi-automatic electrode winder for cylindrical cell and separator assembly in battery R&D laboratories
The Cell Lab Semi-Auto Electrode Winding Machine is a laboratory-scale electrode winder designed for assembling cylindrical battery electrodes and separators with exceptional accuracy and repeatability. Equipped with adjustable speed control (0–170 rpm) and bidirectional winding capability, it allows precise control of winding tension and direction for different electrode formats.
Compact and durable, this benchtop unit supports standard 18650 winding shafts and can be customised for 26650, 32650, or pouch-type cells. The ergonomic design and intuitive operation make it ideal for academic laboratories, pilot-scale R&D, and electrode prototyping across lithium-ion and next-generation cylindrical cell research.
Adjustable Winding Speed
Variable rotation speed from 0–170 rpm allows precise control for different electrode and separator combinations.
Reversible Winding Direction
Switchable between clockwise and counterclockwise rotation for diverse cylindrical cell configurations.
Standard & Custom Shaft Compatibility
Supplied with a round winding shaft for 18650 cells; custom options available for 26650, 32650, or pouch-type assemblies.
Compact Benchtop Design
Space-efficient structure suitable for laboratory benches and glove box environments.
Reliable and User-Friendly Operation
Robust mechanical build and intuitive controls ensure reproducibility and long-term operational stability.
