Precision at every stage of the process – roller solutions for battery production

Our product range includes winding cores, stator rollers, web guide rollers, electric heating rollers, web tension measuring rollers, sensor rollers, and rollers with specific functional coatings – optimally tailored to the requirements of battery production:

  • Substrate production:
    Utilizing aluminium and CFRP guide rollers as well as winding cores for precise, low-tension handling of sensitive substrates.
  • Electrode production:
    Supporting mixing, coating, drying (ideal for dry room conditions), calendering, slitting, and vacuum drying with heating, calender, and web guide rollers.
  • Cell production:
    Used in separating, stacking, contacting, packaging, and electrolyte filling processes – with drive, tension, stator, and sensor rollers for maximum process stability.
  • Cell finalization:
    Supporting forming, degassing, aging, and end-of-line testing with precise roller systems for material protection and quality assurance.

Substrate production & electrode manufacturing – roller technology for precise web guiding & material processing

In battery production, achieving a high-quality end product begins with the precise guidance of the substrate webs. Aluminium and CFRP guide rollers and WinCore® winding cores by INOMETA ensure low-tension and precise web guidance in substrate production, even under demanding conditions like those in drying rooms. Deflection and guide rollers stabilize material flow and prevent web deviations, which is essential for process stability.
Downstream electrode production utilizes highly specialized roller solutions. Calender rollers compact the coated electrodes with utmost precision to achieve uniform layer thickness and maximize the energy density of the cells. Electric heating rollers ensure uniform and efficient drying, guaranteeing reproducible results through targeted heat application. These precisely matched roller types form the foundation for stable and economical production processes.

Quality assurance with measuring and sensor rollers

End-to-end quality assurance is essential in battery production, particularly with high production speeds and strict tolerances. INOMETA utilizes measurement and sensor rollers to record critical parameters such as web tension and web guidance. These rollers function as high-precision control points within the production line, providing reliable data for immediate corrections. The result is minimized waste, stable product quality, and greater process reliability – even with complex product variants.

Cell production & -finalization – rollers for precision and protection of sensitive materials

In the subsequent stages of battery production, especially during cell assembly, maximum control and gentle material handling are crucial. Drive and draw rollers ensure an even material feed, control web tension, and prevent misalignment – essential in sensitive processes like stacking, contacting, or electrolyte filling. These are complemented by highly developed stator rollers operating with minimal breakaway torque. They are ideal for processing delicate material layers and help prevent micro-damage.
Our rollers also ensure a stable web path and trouble-free, automated processes in cell finalization – from forming and aging to end-of-line tests. The result is high reliability with reduced downtimes and consistently excellent cell quality.

WinCore® winding cores – stable carriers for web-shaped materials

Winding cores play a central role in battery production, especially for winding, temporary storage, or transportation of web-shaped materials. In substrate production, they serve as precise carriers for aluminium, copper, or other metallic foils used as current collectors in battery cells, for example. During electrode production – for example, during coating, drying, or slitting – high-quality winding cores ensure an exact, low-tension web run. They are also used as reliable winding cores in cell production, such as during stacking or after cutting electrode webs to size.
Especially in highly automated processes, dimensionally accurate and concentric winding cores are essential for preventing downtime and rejects. INOMETA offers dimensionally accurate, true-running, and thermally stable winding cores made of aluminium, CFRP, or GRP. Unlike cardboard winding cores, they are dust-free, resistant to drying and deformation – a significant advantage in sensitive production environments like drying rooms. This leads to reduced production downtime and waste in the long term.
Another advantage: our optional WinCore® winding cores with winding support ensure optimal adhesion when applying film webs. Manufacturers and processors of copper and aluminium foils particularly appreciate this additional benefit, as it shortens set-up times, increases process reliability, and eliminates the need for manual fixing.

Synergy between roller technologies & digital solutions in battery production

INOMETA’s innovative roller solutions reach their full potential when combined with the INOid® and INOlogic® digital platforms. While INOid® enables the digital identification and traceability of each individual roller – including the retrieval of operating data, service history, or maintenance instructions via QR code or RFID – INOlogic® intelligently integrates this data into higher-level IT and control systems. INOid® thus ensures efficient management of product-related digital assets, supporting after-sales services, and providing seamless documentation of quality certificates and component identification. INOlogic®, on the other hand, captures and processes sensor data directly at the edge, providing valuable real-time operating status information. This enables rapid analysis of process data, facilitates process optimization, and improves product performance through continuous adaptation.

The benefits include

  • automated maintenance intervals,
  • transparent quality data in real time,
  • a consistent database for process optimization,
  • as well as the basis for predictive maintenance.

This smart combination of INOid® and INOlogic® not only guarantees improved process reliability but also enhances efficiency and quality in battery production. Thanks to the seamless integration of these digital platforms with the roller technologies, production is fully ready for Industry 4.0: efficient, scalable, and future-proof.
