Our services at a glance:
Parameter Development, Digitalization & Data-Driven Process Optimization
For our industrial customers, the facility provides an excellent platform for testing new materials, formulations, or adjusted process parameters on a pilot scale without having to interrupt their own high-volume production lines.
Scaling laboratory developments to an industrial scale: We enable you to reliably scale up your laboratory-developed suspensions to a continuous roll-to-roll process.
Feasibility studies for novel cell chemistries: Thorough testing of new materials and concepts under real-world process conditions.
Seamless data integration: We fully integrate the coating machine into our digital infrastructure—from machine control and edge systems to the MES—enabling the seamless collection of all relevant process and quality data.
Sampling of innovative active materials: Testing and evaluating new materials for battery development.
Production of small batches for prototype cells: Precision manufacturing of test and development series for the next validation phase.
Process and Parameter Analysis: Investigating how coating parameters affect the battery's electrochemical performance and lifespan.
Development and validation of new measurement concepts: Opportunities for innovative approaches in battery production and process monitoring.
Integration of inline measurement technology & process monitoring: We measure quality-related parameters such as coating thickness and basis weight using integrated inline measurement systems, store this data in our databases, and thereby lay the foundation for data-driven process optimization.
Point-by-point traceability: We assign process parameters and quality data to the product with meter-by-meter precision and link them across subsequent process steps—down to the electrode segment level. This provides an optimal data foundation for identifying further opportunities for improvement.
Research Questions
The facility enables targeted research into cutting-edge and complex issues in modern battery technology. A key focus is on the following aspects
Investigation of alternative solvents or water-based binder systems and their specific effects on rheology, coating quality, and drying behavior.
Research into new drying technologies: How can thermal and mechanical stresses be reduced through customized, zoned drying profiles to prevent phenomena such as cracking or binder migration in electrodes with particularly high basis weights?
Addressing key rheological and process engineering questions related to optimal slot die coating, in order to minimize edge effects such as edge buildup and ensure a completely uniform coating thickness distribution for the next generation of high-energy cells.
Process development
Bridging the gap between the lab and mass production: We bridge the challenging gap between materials science development on a laboratory scale and the industrial mass production of battery cells.
Battery scaling at an industrial scale: We are establishing a production-oriented yet highly flexible process environment where innovative battery concepts and in-line measurement systems can be scaled, evaluated, and optimized under real-world industrial manufacturing conditions.
Process Efficiency & Quality Optimization: At the heart of our efforts is the consistent improvement of process efficiency (drying vs. throughput) as well as the enhancement of cell performance through the creation of defect-free electrode structures while minimizing material waste.
