What is the MEODEO system from Matthews Engineering?

MEODEO is a full-scale, 1:1 demonstration and production line developed by Matthews Engineering for dry battery electrode manufacturing. It supports lithium-ion DBE, solid-state battery, and ultracapacitor manufacturing, and is commercially available for gigafactory environments.

Where is the Matthews Engineering Development Center located?

The Matthews Engineering Development Center is located in Vreden, Germany. The 1,000-square-metre facility opened in May 2025 and reached full operational readiness in June 2026 with the commissioning of the MEODEO production line.

What battery chemistries does the MEODEO line support?

The MEODEO line supports lithium-ion dry battery electrode production, including NMC and LFP cathode chemistries, as well as solid-state battery and ultracapacitor manufacturing.

How does dry battery electrode manufacturing differ from conventional wet electrode processes?

Dry battery electrode manufacturing eliminates the solvent-based coating steps used in conventional wet processes. This removes the need for drying ovens and solvent recovery systems, reducing energy consumption and factory footprint while enabling thicker electrode designs suited to high-energy-density cells.

What patents protect the Matthews Engineering dry electrode process?

Matthews Engineering's all-in-one dry electrode manufacturing process is protected by four US patents: US12136727, US12237494, US12334534, and US12418017.

What other capabilities does the Vreden Development Center offer?

Beyond the MEODEO production line, the Vreden Development Center includes battery separator film coating lines operating at up to 400 m/min, state-of-the-art dry rooms with humidity control below 1% RH, cleanroom-standard testing areas, laboratory-scale equipment including the GK300L calender, and 3D printing and prototyping facilities.

How does the MEODEO reference line support gigafactory process transfer?

MEODEO operates as a 1:1 scale production reference line, meaning process parameters validated on the Vreden machine are directly transferable to a customer's own gigafactory production equipment. This eliminates scale-up uncertainty between pilot and full production, reducing ramp time and capital risk for battery manufacturers.

What does the MEODEO system's multi-roll calendering architecture enable for solid-state battery production?

The multi-roll configuration allows independent control of roller numbers, hardness levels, and operating speeds across successive nip points. This enables the high compaction forces and precise densification profiles required for thick cathode and solid-state electrode architectures, where conventional two-roll calenders lack the process window flexibility needed for consistent electrode quality at production speeds.

How does the Vreden facility's humidity control specification relate to solid-state battery manufacturing requirements?

Solid-state electrolyte materials, particularly sulfide-based systems, are highly sensitive to atmospheric moisture and can degrade rapidly above trace humidity levels. The Vreden dry rooms maintain humidity below 1% relative humidity, providing the controlled environment necessary for reliable process development and parameter validation with next-generation solid-state cell chemistries.

Matthews Engineering brings battery electrode manufacturing scalability to gigafactory reality

Q: What is the electrode width and line speed of the MEODEO system?

The MEODEO multi-roll calendering system processes electrodes up to 850 mm in width and operates at speeds of up to 150 m/min.

Matthews Engineering has completed its Development Centre in Vreden, Germany, and commissioned MEODEO™, a full-scale dry battery electrode production line designed to close the gap between laboratory R&D and mass manufacturing. The launch, announced on 1 June 2026, marks a pivotal step for lithium-ion and solid-state battery supply chains seeking production-ready process validation at gigafactory scale.

MEODEO™ takes battery electrode manufacturing scalability from lab to production floor

The 1,000-square-metre Development Centre, which opened in May 2025, integrates laboratory, pilot, and mass-production equipment into a single modular architecture. At its centre sits MEODEO™, a multi-roll calendering system engineered specifically for dry battery electrode (DBE), solid-state battery, and ultracapacitor manufacturing.

The system processes electrodes up to 850 mm in width and operates at speeds of up to 150 m/min. Its compact footprint makes it viable across gigafactory floor plans without sacrificing throughput. Four active US patents cover the company’s all-in-one dry electrode manufacturing process, protecting the core technology as customer demand grows.

Brandon Babe, President of Matthews Engineering, frames the commercial intent plainly: “We have designed this next-generation production line based on market demands, and particularly the need to achieve the high speed, yields and uptime for dry cathodes, including NMC and LFP.”

Battery electrode manufacturing scalability anchored by full process-chain simulation

The Vreden centre goes beyond a single demonstration machine. Separator film coating lines within the facility reach speeds up to 400 m/min, while dry rooms maintain humidity below 1% RH for reliable testing of moisture-sensitive materials – a critical requirement for solid-state battery and advanced cell chemistry development.

Frank Bogenstahl, Sr. Director and Global Head of Sales for Matthews Engineering’s Energy business, highlights the centre’s end-to-end coverage: “Our test infrastructure covers the entire equipment spectrum – from laboratory-scale systems like our GK300L to full-size, industrial production lines, namely MEODEO. This enables complete process-chain simulation, precise parameter validation across all scale levels, and the one-to-one transfer of validated process windows into customer production environments.”

That transferability matters for battery manufacturers weighing the total cost of ownership of new electrode processes. Validated process windows replicable directly on a customer’s own line reduce ramp time and de-risk capital investment in gigafactory infrastructure.

A production-ready platform for the energy transition

Thomas Hackfort, Senior Vice President and Technical Managing Director at Matthews Engineering, positioned the fully operational centre as an open collaboration platform, calling on partners, customers, and research institutions to use Vreden for process validation and dedicated testing as they move from development to industrial-scale production.

The launch follows more than a decade of Matthews Engineering’s industrialization work in dry electrode calendering and laminating, anchored by a growing intellectual property portfolio. With MEODEO™ now commercially available for gigafactory environments, the Vreden centre serves as the reference site for the next generation of lithium-ion and solid-state battery production.
