Rollers in battery foil production

Innovative roller and winding solutions for battery foil production

The production of battery foils for anodes, cathodes, and separators is a high-precision process that significantly determines the performance of modern battery cells. Specialized rollers, intelligent winding solutions, and digital technologies are essential to meet the stringent requirements.
A key challenge lies in processing sensitive substrates with minimal web tension, as even the smallest deviations can lead to wrinkles, warping, or damage, thereby impairing cell performance. INOMETA is positioning itself as a leading technology partner that significantly increases efficiency, quality, and sustainability in battery film production with innovative roller and winding solutions and comprehensive expertise.

Precision and process reliability for the highest demands in battery foil production

The production of modern battery cells requires high-precision films with consistent material properties. Furthermore, the extremely low web tension common in battery production is a particularly critical aspect, as it necessitates exceptionally smooth and precise guidance that conventional rollers are often unable to provide.
INOMETA addresses these challenges with a specialized portfolio of smooth-running and precision rollers, as well as winding cores, precisely tailored to the requirements of battery foil production – from coating and drying to calendering and separation.
Customized smooth-running rollers made of aluminium, CFRP, or GRP are utilized for processing copper and aluminium foils as current collectors, as well as for particularly sensitive separator foils. They are characterized by minimal inertia, optimized ball bearing technology, and weight-reduced components. As a result, they enable exceptionally smooth and precise web guidance – even under the most demanding, extremely low web tension conditions

Technological roller solutions for maximum product quality

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, and boosts energy efficiency.

Optimal winding solutions for copper, aluminium and plastic foils

In addition to its comprehensive range of rollers, INOMETA offers high-performance winding systems specifically developed for demanding battery film production. The precise and damage-free winding of extremely thin and sensitive substrates – such as copper, aluminum, PE, and PP films – is a key challenge, especially at high speeds and over long production cycles.
WinCore® winding cores, made from aluminium and fiber composites, provide maximum stability and low weight simultaneously. A particular highlight is the optional winding support, which allows the film to be applied directly without the use of double-sided adhesive tape. This not only significantly reduces setup times but also ensures a clean winding surface and enables immediate reuse of the core.
Furthermore, WinCore® winding cores are available with a cut-resistant surface that protects against damage from cutter knives and extends the cores’ service life, while adhesive tapes can be removed without leaving any residue.

Automation & digitalization in roller maintenance and monitoring

Maximizing system availability and ensuring consistent quality are critical challenges in battery film production. Unexpected failures or undetected process fluctuations can lead to high costs and rejects. Manual monitoring is often time-consuming and prone to errors.
INOMETA combines many years of roller expertise with advanced digitalization to sustainably increase the efficiency and availability of production lines in battery foil manufacturing.
With intelligent sensor solutions and condition monitoring technologies such as INOlogic®, process-critical parameters like temperature, vibration, and load are monitored directly on the roller in real time. This provides the basis for predictive maintenance, reduces unexpected downtimes, and minimizes maintenance costs.
This digital service portfolio is complemented by the INOid® platform, which significantly simplifies the document management of roller components. It enables central, structured storage and management of all relevant information—from technical data sheets and test logs to service and maintenance histories. The complete traceability of all roller components creates transparency and supports more efficient quality assurance. The optional connection to higher-level production and maintenance systems allows data-based decisions to be accelerated and processes to be sustainably optimized – a decisive contribution to process reliability, transparency, and resource efficiency in battery film production.Batteriefolienfertigung.
