Matthews Engineering has officially opened its Development Center in Vreden, Germany, marking the full operational readiness of its advanced facility for battery and energy storage system manufacturing. Central to the center’s capabilities is MEODEO™, a full-scale mass production demonstration line that spans from laboratory validation to gigafactory deployment. The introduction of MEODEO™ reflects more than ten years of expertise in dry electrode calendering and laminating processes, supported by a robust portfolio of technical know-how and patents.
Occupying 1,000 square meters since May 2025, the Vreden Development Center bridges the gap between small-scale trials and large-volume production. It is equipped to accelerate industrial process optimization, support next-generation energy technologies, and deliver sustainable manufacturing solutions. During the Matthews Engineering Energy Summit in September 2025, industry stakeholders witnessed the first full-scale preview of the rotary processing and calendering system now operating on site.
Installed on the ground-floor hall, MEODEO™ serves as a reference line for lithium-ion dry battery electrodes, solid-state batteries, and ultracapacitors. By producing transferable data, the system enables customers to replicate processes on their own production lines and reach industrial scale more quickly. Configurable for varying roller counts, hardness levels, operating speeds, and winding concepts, MEODEO™ is designed to meet diverse gigafactory requirements. Its patented all-in-one dry electrode manufacturing process supports electrode widths up to 850 millimeters and operating speeds up to 150 meters per minute, while maintaining a compact footprint.
Beyond MEODEO™, the center integrates the full spectrum of equipment—from laboratory-scale units like the GK300L to pilot- and mass-production lines—within a modular system architecture. State-of-the-art dry rooms (below 1% RH) and cleanroom conditions support moisture-sensitive testing, while high-speed separator film coating lines operate at up to 400 meters per minute.
Matthews Engineering invites technology partners, customers, and research institutions to leverage the Vreden facility for collaborative development, process validation, and dedicated testing. With the center fully operational, it aims to fast-track the transition of innovative energy technologies from R&D to production readiness.
