Innovative roller solutions for modern battery manufacturing

Maximum performance in battery production – efficiency & precision in the energy sector

Battery manufacturing is a key sector in the modern energy industry, driven by the increasing demand for energy storage solutions in electric vehicles, renewable energy, and portable electronics – a fast-growing and dynamic field of technology with global significance.
While the industry is still in its early stages, there’s a strong focus on developing scalable production solutions to minimize scrap rates. E-mobility, in particular, is demanding higher-capacity, longer-lasting, and more affordable batteries. To thrive in this dynamic market, we offer the highest quality standards and advanced technologies for enhanced efficiency.
With our expertise in web-guiding and rotationally symmetrical components like rollers and lightweight parts, including custom functional surfaces, we help ensure safe, efficient, and cost-effective production lines for the battery industry.

Customized & innovative roller solutions for all production processes in battery and fuel cell manufacturing

Our state-of-the-art manufacturing facility is specially designed to meet the demanding requirements of the battery industry – from precision-engineered rotationally symmetrical components to high-volume manufacturing for large-scale production lines, we offer solutions tailored to the specific needs of battery production:

• Web guidance with unique web guide rollers – designed for use in the dry room
• Coating solutions for calender rollers, guide rollers and draw rollers
• Web tension measurement rollers with the highest level of precision even with minimal web tension
• Electric heating rollers
• High-precision & sustainable aluminium and fiber composite winding cores (WinCore^®)

We provide solutions for integrating our rollers into various battery production processes:

• Substrate production: Our aluminium and CFRP guide rollers and winding cores ensure precise handling and processing of substrates.
• Electrode production: Our roller solutions support mixing, coating, drying (our guide rollers are ideal for dry room environments), calendering, slitting, and vacuum drying.
• Cell production: Our rollers enable efficient processing during separation, stack production, contacting, packaging, and electrolyte filling.
• Cell finalization: Our products support pre-treatment, forming, degassing, aging, and end-of-line testing.

Our product range includes winding cores, stator rollers, web guide rollers, heating rollers, web tension measuring rollers, sensor rollers, and rollers and winding cores with specialized functional surfaces (coatings). We also provide a comprehensive roller service, from on-site analysis and inspections to personalized advice and a tailored repair and recoating program for CFRP, GRP, aluminium, and steel rollers. This ensures the highest quality and efficiency in battery production.

Efficient web guiding and precision for maximum productivity

Web guiding is a key factor in the production of batteries. INOMETA supply innovative precision smooth-running rollers that are also suitable for use in dry and clean rooms. These rollers enable particularly gentle handling of sensitive materials such as separator foils and electrode coatings. They are characterized by minimal friction and smooth running, which increases production speed and reduces material damage at the same time. The use of these rollers in large production lines with working widths of up to 2 meters ensures that consistently high quality is achieved even with high production capacities.

Customized coating solutions for the highest requirements

Calendar rollers and other rollers used in electrode and film processing must be exceptionally resistant and precise to handle the delicate materials used in battery production. Our custom-engineered functional coatings for steel, aluminium, and CFRP meet these demanding requirements. These coatings combine excellent wear resistance with exceptional traction.

Our specially developed, customer-specific coatings are ideal for safely transporting highly sensitive web surfaces. They are electrically conductive, making them well-suited for use in drying rooms. Additionally, our PROTEK^® coatings offer superior wear resistance and minimal surface roughness, ensuring optimal substrate guidance through excellent traction and sliding properties. These characteristics contribute to extended roller service life and reduced maintenance requirements.

Precise web tension measurement for optimum material handling

To ensure consistent and high-quality production, precise web tension measurement and control are essential. INOMETA offers high-accuracy web tension measuring rollers that provide reliable data even at the lowest tension levels. This is particularly important for handling thin and sensitive substrates like copper or aluminium foils, preventing deformation or damage. Precise web tension control leads to greater process stability and reduced waste, significantly improving efficiency in battery production.

Electrically heated rollers for even heat distribution

In numerous battery manufacturing processes, such as the drying of electrode materials or the lamination of foils, a uniform heat supply is essential. INOMETA’s electric heating rollers provide precise temperature control and ensure even heating across the entire roller surface. This minimizes temperature variations and guarantees consistent product quality. In sensitive areas like electrode production, stable heat conduction is essential for optimal material preparation and processing.

WinCore^®: High-precision and sustainable winding cores for maximum efficiency

Another standout in INOMETA’s product portfolio is our WinCore^® winding cores. Made of aluminium and fiber composite materials, these winding cores offer exceptional stability and lightweight design. They are perfect for winding processes in battery production, ensuring precise and wrinkle-free winding of materials like separator foils and electrodes. Due to their durability and sustainability, WinCore^® winding cores in various designs contribute to reduced total cost of ownership and minimized resource consumption.
