Solution in Detail
- The Mathis AG solution for battery electrode production focuses on precise coating, drying, and calendering of anode and cathode materials for lithium-ion and other advanced battery chemistries. The main outputs include uniformly coated electrodes, calendered foils, and ready-to-assemble battery components, all with strict adherence to thickness, quality, and safety standards.
- Coating: Electrodes are coated using high-precision methods such as slot die, reverse roll, or doctor knife coating, depending on the application. The system accommodates aqueous and solvent-based slurries, with the substrate fed via automated unwinding and web-guiding modules to maintain micron-level uniformity.
- Drying and Solvent Management: Coated electrodes undergo multi-zone drying with hot air, infrared, or floating dryers, delivering precise temperature and airflow control. Integrated LEL monitoring and solvent recovery/RTO systems ensure safe handling of volatile solvents while minimizing environmental impact.
- Calendering, and Quality Control: Advanced calendering modules provide consistent electrode density and thickness. In-line sensors and the Siemens or Univision controller enable closed-loop feedback, data logging, and recipe management for reproducible quality from lab to full-scale production.
- Scalability and Testing: Mathis AG systems are modular and fully scalable, ranging from laboratory R&D (LTE-S) to pilot (KTF-S) and full-scale production lines (BA). Pilot-scale testing and process optimization can be conducted at Mathis facilities, allowing customers to validate performance before commissioning.
- Customization and Integration: Mathis AG delivers tailored solutions, integrating coating, drying, calendering, lamination, web handling, and process control into complete turnkey production lines. Their modular approach allows easy upgrades or adjustments for emerging battery technologies, ensuring future-proof, efficient, and safe operations.

Operational Details
Automation Level
Available in manual, semi-automated, and fully automated configurations depending on system size.
Software & Controls System
Proprietary «UNIVISION» Process Controller based on Siemens S7-1500 PLC architecture. Provides centralized control for coating, drying, calendering, and web handling modules, with closed-loop feedback, data logging, and recipe management. Supports OPC UA, TCP/IP, and REST API connectivity for MES/ERP integration, remote diagnostics, and traceable process documentation.
Safety System
Integrated LEL (Lower Explosion Limit) monitoring, solvent recovery or RTO systems, and automatic purge cycles for solvent operations.
Emergency stop circuits, process interlocks, and negative-pressure dryer design ensure safe handling of volatile materials. Continuous safety supervision is embedded within the UNIVISION control system, enabling alarms, shutdowns, and compliance with CE and ISO safety standards.
