We develop and refine custom chemistries – from electrode powders and binders to functional primer layers – optimized for compatibility with both wet and dry coating processes. Our labs support slurry formulation, solvent-free processing, and material characterization, ensuring consistency, performance, and compliance.
Our process engineering experts design tailored manufacturing workflows – including DBE-specific configurations – with simulation-based validation and performance modeling. We define optimal coating, drying, calendering, and lamination setups to support high-efficiency, high-throughput production.
We offer inline diagnostics, AI-driven metrology integration, and predictive maintenance strategies to maximize uptime and yield. Our continuous support includes remote diagnostics, process tuning, and global field service to adapt lines to new chemistries or performance targets.
We provide complete electrode production systems for both wet-coated and dry-processed formats. Our multi-roll calenders and slot-die coating lines ensure precise control of thickness, porosity, and density — essential for energy-dense, stable battery performance.
Our separator film coating lines are engineered for tension-sensitive microporous substrates. Featuring non-contact drying, advanced web handling, and dual-side coating in a single pass, they ensure uniform ceramic or functional coatings at production speeds up to 200 m/min.
From lab-scale test rigs to full gigafactory installations, we manage all stages of deployment — including pre-assembly, factory and field acceptance testing (FAT/SAT), and operator training. Every system is designed for seamless integration, long-term operability, and global support.
