Laboratory Calender GK 300 L for Battery Research & DevelopmentEngineered for precision in battery electrode R&D
Designed to replicate industrial calendering conditions in a compact lab environment, this machine empowers battery R&D teams to fine-tune process parameters, analyze material behavior, and optimize cell performance — all before scale-up.
From graphite anodes to cathodes and solid-state films, this system handles the full range of battery electrode materials. Its dual-position (vertical or horizontal) configuration ensures flexible integration into lab environments, making it ideal for dry electrode studies, binder system evaluations, and separator trials.
Simulate roll-to-roll calendering with precision. The system supports line speeds up to 5 m/min and delivers up to 15 tons of compaction force with ±1 µm gap accuracy. It’s the perfect environment for replicating pressure, thickness, and mechanical characteristics relevant to production-scale battery lines.
The calender can be configured with components such as rewinders, unwinders, heated rollers, and cutting units. An optional electrohydraulic upgrade with a mobile control panel gives you advanced control over pressure profiles and gap settings — ideal for evaluating densification behavior or developing new layering techniques.

From advanced pressure control to web handling and heating configurations – discover how our proven features drive your innovations.
Position vertically or horizontally, depending on your lab layout. Pre-configured mounting and quick-connect systems make setup fast and precise.
With a working width of 300 mm and adjustable speed up to 5 m/min, the calender is ideal for small-batch trials and full-parameter evaluations.
Fine-tune compaction using a precision ratchet and wedge system — even under load. Independent left/right adjustment ensures consistent pressure distribution across the electrode width.
Gap force up to 15 tons, ±2 µm accuracy, and real-time feedback from high-resolution sensors make it easy to simulate production-grade compression and calendering.
Includes an infeed table for sheets and web formats, powder hopper for dry materials, and guide rollers for flexible routing of electrode or separator materials.
Upgrade your setup with unwinders, rewinders, heated rolls, cutting units, and additional guide rollers — all configured to match the specific requirements of electrode development.
Advanced regulation of pressure and gap settings (up to 250 bar) via mobile touch panel — ideal for testing variable densification, stack layering, and roll pressures.
