Calendering System for Continuous Coated Battery Electrodes

Precision calendering for continuous coated battery electrode excellence

battery electrodes

Performance meets precision

Our system combines direct-driven roller synchronization, tight thermal and mechanical control, and real-time data insights to optimize electrode thickness, density, and surface finish across every meter of web.

 

Designed to handle delicate coated substrates under high loads, the system ensures uniform mechanical compaction, improves downstream process stability, and supports high-throughput roll-to-roll manufacturing.

 

Whether you’re calendering cathodes or anodes, our flexible configurations adapt to different electrode chemistries, line speeds, and production environments – bringing digital intelligence and mechanical mastery together for superior electrode formation.

Roller Synchronization

Each calender roller is independently direct-driven, ensuring precise torque balance, smooth acceleration, and minimized mechanical backlash – delivering ultra-stable operation and reduced maintenance over time.

Compact Footprint

Built with a rigid, space-efficient frame, the calender maintains high structural integrity under load. This guarantees even pressure distribution across the web for consistent compaction – while minimizing the system’s floor space impact.

Electrode Uniformity

Advanced control of roller temperature and gap spacing (±1 μm accuracy) enables highly repeatable electrode densification. This results in uniform coating thickness, optimized porosity, and improved electrochemical performance.

Custom Configuration

Available in a range of web widths, roller surface treatments, and tension management systems, with thermal oil or electrical heating. Easily adapted for specific electrode types, coating thicknesses, and production workflows – inline or offline.

Digital Intelligence

IIoT-enabled sensors and integrated control systems offer real-time monitoring, predictive diagnostics, and historical data visualization. Gain actionable insights to minimize downtime, optimize throughput, and ensure quality consistency.

Enhance performance with tailored add-ons

Our calender systems are modular by design, allowing you to expand functionality based on your production goals, substrate properties, and automation level.

 

Whether you’re optimizing for speed, traceability, or material cleanliness, these optional features integrate seamlessly to elevate your line’s performance and reliability.

Control Engineering: Electro-Hydraulic

Delivers high-precision force regulation through an electro-hydraulic control loop—ensuring stable nip pressure across variable web loads for consistent compaction and minimal deviation.

Thickness Measurement (Non-Contact)

Inline, laser-based thickness measurement provides real-time coating and calendering feedback without touching the material—improving quality assurance and enabling closed-loop process control.

Web Cleaning Device (Non-Contact)

Removes fine dust and particulate matter from electrode surfaces using ionized air or brushless systems—preventing contamination and defects before compression.

Preheating (IR-Field, S-Roll Design)

Infrared or S-Roll thermal modules elevate coating temperature before calendering, improving material flow, binder activation, and final electrode density uniformity.

Cutting Units

Integrated slitting or cross-cutting systems allow precise web dimensioning inline—ideal for converting wide master rolls into downstream-process-ready widths.

Splice System

Enables automatic or semi-automatic roll changes with minimal line interruption—maintaining continuous production and reducing material waste during transitions.

Remote Maintenance

Secure, cloud-enabled diagnostics and support access allow our engineers to troubleshoot, update, or optimize your system remotely—reducing downtime and service response time.

Inspection System

High-speed visual or sensor-based inspection detects surface defects, coating irregularities, or material inconsistencies—ensuring early quality intervention and batch traceability.

Marking System

Applies codes, batch numbers, or quality marks directly onto the web—enabling precise traceability and simplifying downstream logistics and compliance processes.
