Another key challenge in battery film production is continuously ensuring the highest product quality in complex thermal processes and the need to reliably detect and control extremely low tensile forces. Uneven temperature distributions can lead to material fluctuations, while imprecise web tension control carries the risk of material damage or uneven layer thicknesses.INOMETA’s roller portfolio offers the ideal technological solutions for this, including high-precision web guide rollers, wear-resistant coating and calender rollers, and particularly sensitive web tension measuring rollers. INOMETA is one of the few manufacturers capable not only of reproducing these extremely low web tension values but also of measuring and actively controlling them with the utmost precision – a key requirement for the reliable processing of highly sensitive battery films and for preventing rejects.A further highlight is our electrically heated INOheat® rollers. They resolve the challenge of uneven temperature influences by ensuring homogeneous temperature distribution over the entire length of the roller – essential for thermally sensitive process steps such as electrode coating and drying. Their media-free, compact design also reduces maintenance costs, enhances system safety.
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.
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.
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.
Calender rollers and other rollers used in electrode and film processing must be both highly resistant and precise to optimally handle the delicate materials used in battery production. Our specialized coatings for steel, aluminium, and CFRP meet these demanding requirements. They combine exceptional wear resistance with excellent traction.Our custom-designed coatings, tailored to specific customer needs and applications, are ideal for safely transporting highly sensitive web surfaces. They can be formulated to be electrically conductive, making them ideal for drying rooms. Additionally, our PROTEK® coatings are known for their high wear resistance and minimal surface roughness, ensuring optimal substrate guidance through excellent traction and sliding behavior. These properties contribute to minimizing maintenance intervals and significantly extending the service life of the rollers.
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.
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 (INOheat®) 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.
Another highlight in INOMETA’s product portfolio are our WinCore® winding cores, including the Ecoline and Proline series and our WinCore® winding cores with winding support and cut-resistant surfaces. Made from aluminium and fiber composite materials, these cores offer maximum stability and low weight. They are ideal for winding processes in battery production where substrates such as separator foils and electrode foils need to be wound precisely and crease-free. Thanks to their long service life and reusability, WinCore® winding cores can help reduce the need for single-use winding cores and lower total operating costs over their service life.
